REPLACEMENT OF THE POWER MODULE WARNING!

Warning!

DO NOT ATTEMPT ANY WORK ON A POWERED ACS800! There is a dangerous voltage inside the cabinet. After the mains voltage is disconnected by means of the main switch, a high voltage remains in the capacitor bank of ACS800, which is discharged through discharge resistors. WAIT AT LEAST FIVE MINUTES BEFORE ATTEMPTING ANY WORK ON OR WITH THE UNIT! Always ensure by voltage measurement that the DC voltage has dropped to zero and the mains voltage is disconnected (zero) before performing any service or main circuit connections. Measure the DC voltage between terminals UDC+ and UDC- and the mains voltage between terminals U1, V1 and W1 (L1, L2 and L3). The meter must withstand 1000 VDC and 750 VAC. For more details, see Safety Instructions in the ACS800 Hardware manual.

CAUTION!

ONLY A QUALIFIED ELECTRICIAN SHOULD CARRY OUT THE ELECTRICAL INSTALLATION!

Electrostatic Discharge (ESD) can damage electronic circuits. Do not handle any components without following ESD precautions. For more details, see ABB Oy ESD Directive.

ABB Oy Replacing the POWER 64549910 BU Drives, Helsinki 00154838_C.DOC Module DEPT PREPARED DATE APPROVED Revision PAGE EJQ Ilkka Ikonen 08.03.2005 K. Ingman C 2/13 Power Module Handling Precautions

Caution must be observed in both transport and handling of semiconductors. IGBT and other modules can be destroyed by static electricity. Therefore, the following precautions should be observed during handling. - When handling a power module, hold the package and avoid touching

the terminals, especially the gate terminal. - Always use an earthed wrist band when handling a power module.

Accessing the POWER Module

- Clear a suitable space outside of immediate work area for removed screws, bolts, components and subassemblies to avoid mislaying or damaging them.

- Study Safety Instructions in the ACS800 Hardware manual. - Disconnect the mains supply. - Wait at least five minutes. - Remove the front cover of the ACS 800 Unit. - Measure the DC voltage and the mains voltage. The voltages must be zero

before you continue working on the unit. - Install the wrist band and the earthing mat according to ABB Oy ESD

Directive. - Put the wrist band on your wrist. - Remove the boards and busbars to access to the power module. - Remove the wiring. - Remove the faulty power module. - Clean the heat sink surface with an appropriate solvent (e.g. Grafol) and a

soft cloth from excess thermal compound and particles.

Thermal Compound

The recommended thermal compound type is WPS II. The power module spare parts kit includes a tube of thermal compound.

When installing a power module on a heat sink, the following instructions should be applied to maximise the effect of the heat sink and to minimise the stress concentrated on the power module.

4-screw-type power modules

- Clean the base of the module with an appropriate solvent (e.g. Grafol) and a soft cloth from particles.

- Apply a thin layer of thermal compound with a rubber spatula or with the

roller on the base of the module. The thermal compound layer should be as thin as possible but metal should not be visible through the compound (figure 1).

Figure 1. Thermal compound applied to power module

- Put the power module on the heat sink and press by hands to extend the

thermal compound. Press at least 5 seconds. - Tighten the screws to a pre-torque according to tables 1, 3 and 5 in sequence

1-4-3-2 according to Figure 2 .

Figure 2. Upper view of the power module

- Tighten the screws to the final torque according to tables 1, 3 and 5 in

sequence 2-3-4-1 according to Figure 2. - After the tightening a small rim (1 – 4 mm) of thermal compound must be

seen around the mounted module. This shows that amount of thermal compound is sufficient.

- Wipe off the excess of thermal compound. - Use the torques according to tables 2, 4 and 6 to connect busbars and cables

to power modules.

2-screw-type power modules

In case of two screw type power modules follow the steps of 4 screw type modules applied to 2 screw type modules. Assembling and connection torques can be found in tables 1-10.

8-screw-type power modules

In case of eight screw type power modules follow the steps of 4 screw type modules applied to 8 screw type modules except tightening instruction wich is presented below. Assembling and connection torques can be found in tables 1-10. Tighten the screws to a pre-torque according to table 1 and in sequence 2-6-3-7-4-8-1-5 according to Figure 3 .

Assembling and connecting torques of all power modules used in ACS800 frequency converters can be found in tables 1-10. Tables 11-15 consist second source lists of power modules. The right assembling and connecting torques can be found with module or spare part code. If the spare part kit contains other power module type than mentioned in tables 1-10, please check the correspondence from tables 11-15. Second source modules have same pre and final torques with the first source power modules except Fufi and Mitsubishi IGBT modules (see note below the table 1).

For R7 and R8 frame sizes the number of the spare part articles is reduced by combing current and voltage classes, because of this never use as a spare part the second source component of the spare component mentioned in the table. For example although TD425N18KOF is second source for SKKH500/18 it doesn’t cover the current ratings which SKKH500/18 is capable when used instead of SKKH500/16 as spare part. When changing the input bridge modules it is recommended to replace all three modules at once.

Ingman C 13/13 Short circuiting unnecessary gate-emitter terminals in R7 and R8 brake choppers In R7 and R8 frame size converters the used/replacement Brake IGBT module might in some cases have another pair of gate-emitter connectors (depending the module type and supplier, in type code either FF or GB) which must be shorted, otherwise the module turns on by itself . Use the delivered short circuit wire(s) to short the connectors 4 and 5 (gate and emitter of the upper leg IGBT) of each module.
