2.3 ESD PRECAUTIONSNo ESD precautions have to be taken by the operator in the daily use of the equipment. Theequipment is designed and manufactured in such a way to not be sensible to electrostaticdischarges.

2.3.1 ESD Precautions in Maintenance/Installation

The equipment includes many electrostatic-sensitive parts that must be handled at a static-safeguarded working area. Furthermore, they must be arranged in static-safeguardedpackages, either in the case of storing, or in the case of shipment.These recommendations should be followed with the maximum care, especially in the case ofmodules or board extraction and handling, for installation or maintenance activity, etc.A static safeguard area may be intended as:

• Grounded static dissipating wrist-strap that drains static charge from the operator wearing it.• A work surface covered with or composed of a grounded, static-dissipating material that

drains electrical charges from devices placed on the surface.

In the AK100/S rack version, the rack surface should provide a standard-size ESD-safeguardsnap suitable for snap-stacking wrist-strap connection. It should be used as a convenient ESDcaution, whenever handling modules and boards. These recommendations are to be extendedalso to activity not strictly performed in close equipment surrounding. If removed, replaced, orlocated inside workshop, any board should be handled by means of convenient ESD cautions.

WARNING Please note that OTE disclaims any responsibility for problems due topoor ESD protection during installation/maintenance activity.

• The front connection circuit has the purpose to allow connection of the various audioaccessories to the equipment, by means of three sockets placed on the front panel, andsends all the signals to the Base circuit that contains the circuits for microphone andheadsets amplification. This circuit also features LC filtering to prevent RF feedback onaudio lines.The connectors suitable for connection of audio ancillaries are:

- HANDSET; for connection of handmicrophone with PTT.- MICROPHONE; for connection of electret or dynamic microphone with PTT.- HEADSET; for connection of a headset composed by an electret microphone and two

earphone caps.• The External Loudspeaker connector allows the connection of an external 4Ω/3W

loudspeaker. The presence of the external loudspeaker disabled the AK100/S internalLoudspeaker.

• The Pushbuttons, LEDs and potentiometers circuit has the purpose to arrange in the samePCB all the pushbuttons, LEDs and potentiometers for "Loudspeaker" and"Handset/Headset" volume adjustment. The circuit connection to Base Circuit is done by aflat cable.

• The Alarm controller circuit allows the alarms management in case of AK100/S connectedto a DTR100 or to a couple of DT and DR radios (see Setting-up section for further details)

• The Base circuit hosts almost all of the circuits of the AK100/S equipment:- Filtering circuits for input/output signals to prevent EMI.- Microphone line audio amplifier circuits.- Audio amplifier circuits for headset, microtelephone, internal loudspeaker and for the

tape recorder output.- Voltage regulator that generates +8Vdc starting from external +12Vdc (either from

power supply, or from emergency battery).- A logic circuit that generates enabling signals, from PTT, squelch and incoming

signals from Pushbutton LEDs and Potentiometer circuit.The microphonic signals present on audio connectors (after their enabling by the logiccircuits) reaches the mixer and the result signal are sent to the radio equipment after anamplification stage.The RX audio signal coming from the radio equipment is before amplified and than it is sentto potentiometers placed on the front of AK100/S for volume adjustment of handset/headset.The RX signal is sent to audio connectors after enabling by the squelch.TX and RX audio signals are sent to a mixer that provides merging themselves for recorderpurpose. When the PTT or squelch signals are active the "PTT" or "SQ" LEDs placed on the front ofAK 100 equipment are lit.The signals incoming from "HEADSET OFF"and "SPEAKER OFF" allow respectively forheadset/earphones disabling and loudspeaker muting.The ALM frontal indicator is active in the following conditions:

- an alarm is occurred on the radio;- DTR100 or one between DT100 and DR100 is/are disconnected;- one radio equipment is in “not ready” state;- one radio is switched off.

The Power supply voltages are routed to the AK100/S power switch, and their lines are alsoequipped by fuse for over-current protection. The 12Vdc supply is finally sent to voltageregulator stage, where a stabilized +8Vdc is generated for circuit supply. When this voltageis present the "PWR" led placed on the front of AK 100 is active.

Power Supply section. This section provides circuit supply. The 12VDC inputs voltages areconnected, through an OR block, to one mechanical switch on the front panel (the 12VDCBATTERY voltage is a back up source). The Input stage provides filtering and protectionsagainst interferences as well as over-currents and over-voltages. The DC input voltage passesthrough a DC/DC converter stage to generate the required +8VDC supply voltage. This stageincludes also filtering for output.Signaling section. This section provides interface between the external devices (DTR100 orDT/DR100 typically) and the AK100 console. It is the analogue interface of equipment towardtelephone line, handling audio, PTT, Squelch signals. PTT/Squelch signals areencoding/decoding by universal E&M (Ear and Mouth) interfaces.The E (Ear) input signal is associated to Squelch signal and M (Mouth) output signal isassociated to PTT signal.

7.2.1 Environmental

The equipment is designed for indoor installation only. Equipment room must allow theequipment to operate within the rated environmental range limits.In addition, it is important to note that the operating environment must be safe wrt the followingagents:

• Water floods. In environment potentially subject to flooding, the equipment should not beplaced on the cabinet bottom, if not protected against water access.

• Dust. It is important to take all the necessary cares to avoid dust presence inside thesurrounding environment. Sites located close to excessive airborne dust clouds (e.g. due tocement, coal, etc) require additional cares in order to avoid contamination of the coolingsystem and increased maintenance.

• Rodents. Especially whenever false (floating) floor is present, rodents may attempt tocabling safety.

• Acids or other corrosive agents. Especially whenever UPS system provided withrechargeable acid-type batteries are present inside the equipment room, acid or corrosivevolatile substances may attempt to equipment integrity.

• Saline environments. Saline environments may result dangerous for equipment integrity,with special reference to cabling and connections. Installation on coastal sites should not beface directly prevailing sea winds or sprays, e.g. caused by windows opening.

7.2.2 Mechanical

The equipment is designed to match 19" rack-standard cabinets or in a table Console, andrequire a useful depth of more than 400 mm. In addition, space for power, signal and datacabling arrangement should be taken in account on the rear side of the equipment.If AK100/S is located in a rack, it must be accessible from rear side (e.g. provided with reardoor), to allow access to controls for maintenance.

7.2.3 Power and Grounding

Concerning power and grounding safety aspects, the installation must be realized in compliancewith national applied regulation and standard. The equipment installation category is II inaccordance with IEC664, this recommendation is also applied to the backup DC power supplyinput.According to the minimum DC operating voltage, cabling must be sized to handle max. 2 Acurrent. Therefore a pair of AWG 16 (or 1 mm2) cables should be used; it is recommended touse AWG 14 (or 2 mm2) when length exceeds 15 meters, to not introduce significant voltagedrop. Cables must be terminated at the equipment end with specific AWG 14 or AWG 16crimped-plug terminals.It is important to note that the equipment is provided with a mechanical grounding point thatmust be connected with the equipment room grounding bar via a dedicated cable withresistance lower than 0.1 ohm, according to EN 60950.

7.2.4 Supply Lines Protections

Concerning external AC supply line, it is important to note that a magneto-thermal anddifferential circuit breaker must be installed for protection, allowing for both phases breaking(live and neutral).

779-0187/01Issue 05 – March 2004

779-0187/01Issue 05 – March 2004 61

Breaker must have 0.6A/250V nominal current and voltage figures, and breaking interventionmust be in the range 1.5 to 3 A. Differential intervention threshold must be 20 mA.If the equipment is powered through a power switchboard, the breaker may be convenientlyarranged within the switchboard, also providing selective ON/OFF switching.In any case the protection device/system must be in full respect of requirements stated bynational applied regulation and standard.

WARNING The PSU module does not fully disconnect the equipment from both ACand DC sources, even when its switches are in OFF position. PSUmodule should be removed from the equipment only once that theexternal breaker has been switched OFF, or external DC supply has beendisconnected.

Backup DC supply line does not require mandatory external protection, in any case the use ofan external 2 A fast-acting fuse on the positive pole may be useful for further protection on theDC distribution system, e.g. against accidental shorting.If the equipment is DC-powered by external battery pack, the use of an external 2 A fast-actingfuse on the positive pole, together with a circuit switching breaker, is mandatory, in order toallow safe battery replacing and maintenance without disconnecting cabling. The battery shouldpossibly be placed in a different environment than the equipment; this environment must beaerated, and battery poles must be protected wrt accidental contacts.

WARNING In no case, any of the equipment protecting fuses must be replaced withfuses of different type, nominal figures and/or different operatingcharacteristics.

7.3 MECHANICAL INSTALLATIONThe equipment is designed to be installed in a Console or into a 19" standard cabinet. Followingsections detail the guidelines for the mechanical installation, together with additional informationabout equipment handling.
