Chapter 4 Maintenance
Routine Maintenance
The following should be carried out on an annual basis or whenever a contactor is
serviced:
Cleaning
1. Ensure that metal chips or filings are cleaned from around the
electromagnet assembly (coil core pole face and mating armature plate) as
they may affect proper operation of the contactor. Vacuum clean if
necessary.
2. If dirty, clean the white ceramic area of vacuum bottles with a clean lint-
free cloth.
ATTENTION: Before performing any maintenance on the contactor, refer to the
User Manual of the starter configuration in which the contactor is installed for
all service instructions and procedures. Failure to do so may result in injury to
personnel or damage to the controller or contactor.
ATTENTION: To avoid shock hazards, lock out incoming power and disconnect
the control plug from the contactor before working on the unit. Verify with a hot
stick or meter that all circuits are voltage free. Failure to do so may result in
severe burns, injury or death.
IMPORTANT Do not use compressed air to clean or remove dirt from surfaces or the
enclosure as it will only redistribute the dirt.
