Safety Precautions

PROPER GROUNDING Never power up the indoor equipment not yet connected to a proper grounding system. There is risk of equipment failure and/or electrical shock. Ensure that both the indoor and outdoor grounding systems measure a path resistance less than 10 Ω.

ESD PROTECTION Always use proper antistatic protection (i.e. grounding bracelet, antistatic bags, etc.) when handling the IDR-C cards. Parts bearing the ESD sign (see left) have ESD sensitive exposed components.

23

Grounding the IDU

Prerequisites • This procedure requires a prepared grounding cable according to the

description on page 19. • Make sure that the installation premises is equipped with a reliable,

low-impedance ground connection system.

Tools Philips screwdriver for M5 screws

Accessories • Grounding cable (see par. “Preparing the IDU Grounding Cable”, on

page 19) • M5 x 10 screw (provided, it is screwed on the right side panel of the

unit)

Step Action 1 Use the M5 x 10 screw and the two washers provided to

connect the yellow grounding lug to the IDU.

2 Connect the other insulated grounding lug to the rack

grounding bar.


24

Connecting the E1 Tributaries

Prerequisites This procedure requires that you have prepared the cables for the E1

tributaries.

NOTE

The manufacturer can provide on request a special conversion panel with BNC receptacles for the 75 Ω E1 tributaries. The conversion panel is connected to the IDU through special D25/BNC conversion cables (see page 17) provided by the manufacturer.

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16

Procedure Connect the E1 tributaries to the DS 1-4, DS 5-8, DS 9-12, DS 13-16

connectors on the front panel of the IDU MUX.

In case you have the conversion panel

If you have the aforementioned conversion panel with the BNC receptacles for the 75 Ω E1 tributaries and in order to connect the E1 tributaries to the IDU, follow the steps below:

Step Action

1 Plug the D25 connectors of the conversion cables to the DS 1-4, DS 5-8, DS 9-12, DS 13-16 connectors on the front of IDU.

2 Remove the washer and the nut from each BNC receptacle of the conversion cables.

4 Connect the E1 tributaries to the appropriate BNC receptacles of the conversion panel.


25

Connecting the Power Supply

Prerequisites • The IDR-C operates only on negative power supply, from -40 V dc to

–60 V dc. • The positive pole of the power supply source at the IDR-C station

should be grounded. • The suggested value for the fuse of the power supply source at the

IDR-C station is 10 A. • This procedure requires that you have prepared the power supply

cable as described on page 18.

Accessories Power supply cable (see par. “Preparing the Power Supply Cable”, on

page 18).

Procedure To connect the power supply to the IDR-C, follow the steps below

taking into consideration the following Caution:

Risk of arc production at the contacts of the IDU PSU connectors! Do not connect the power supply to the IDR-C before you make sure the positive pole of the power supply source at the IDR-C station is grounded.

Step Action

3 Connect the power supply cable(s) to the station power supply source.

4 Plug the power supply cable(s) to the power supply connector(s) on the front panel of the PSU(s).

NOTE

In 1+1 topology, cable both PSUs of the IDR-C.


26

Connecting the RG-142 Tail Cable

Why to make the connection

You should connect the IF cable coming from the Outdoor Unit to the RG-142 tail cable to protect the ODU connector on the front panel of the IDU against mechanical damage which might occur in case of direct connection of the heavy IF cable.

Accessories RG-142 Tail Cable (provided)

Procedure Connect the male connector of the tail to the ODU connector on the

front panel of the IDU.
