Service Instructions

Transistor and Thyristor (SCR) Replacement for

1336 PLUS, PLUS II, FORCE, IMPACT and

REGEN Drives

Description

These instructions cover the proper method of replacing transistor and SCR

modules in the 1336 family of drives. Failure to properly prepare the

mounting surface or to torque the components to rated specifications will

result in decreased service life of the replacement components.

Safety Precautions

ATTENTION: Some printed circuit boards and drive

components may contain hazardous voltage levels. Remove and

lock out power before you disconnect or reconnect wires, and

before you remove or replace fuses and circuit boards. Verify bus

voltage by measuring the voltage between +DC and - DC on

Terminal Block TB1. Do Not attempt to service the drive until

the bus voltage has discharged to zero volts.

ATTENTION: Potentially fatal voltages may result from

improper usage of oscilloscope and other test equipment. The

oscilloscope chassis may be at a potentially fatal voltage if not

properly grounded. If an oscilloscope is used to measure high

voltage waveforms, use only a dual channel oscilloscope in the

differential mode with X100 probes. It is recommended that the

oscilloscope be used in the A minus B Quasi-differential mode

with the oscilloscope chassis correctly grounded to an earth

ground.

ATTENTION: This assembly contains parts and

sub-assemblies that are sensitive to electrostatic discharge. Static

control precautions are required when servicing this assembly.

Component damage may result if you ignore electrostatic

discharge control procedures. If you are not familiar with static

control procedures, reference Allen-Bradley Publication

8000-4.5.2 Guarding Against Electrostatic Damage, or any other

applicable ESD protection handbook.
