Further adjustment should not be required unless a malfunction occurs and/or certain
critical parts or assemblies are replaced.
If the procedures in this section and the circuit descriptions contained in Section 1
do not provide sufficient information to locate and correct a malfunction, request
assistance from the Elgar Customer Service Department. Equipment should not be
returned to the Elgar factory without express authorization from Elgar or its appointed
representative. Elgar cannot assume the responsibility for equipment returned without
authorization.
WARNING
Hazardous voltages are present when operating this equipment.
Please read the Safety Notice at the beginning of this manual before
performing any installation, operation, or maintenance procedures.

2.2 FACTORY REPAIR

TW systems requiring repair during their warranty period should be returned to Elgar
for service. Unauthorized repairs performed by anyone other than Elgar during the
warranty period may void the warranty. Any questions regarding repair should be
directed to the Elgar Customer Service Department.
This service manual was intended for use in the troubleshooting and repair of TW
systems down to the module level. Do not attempt to repair damaged modules as
further damage or personal injury may result.
Some systems may not be field repairable and will need to be returned to the factory
for repair. If it is necessary to return a module or entire system to the factory for repair,
first contact the Elgar Customer Service Department to obtain a Return Material
Authorization (RMA) number. See the warranty page at the front of this manual for
details. DO NOT RETURN THE UNIT FOR REPAIR WITHOUT AUTHORIZATION.
