Transfer Switch

6.0 Maintenance

DANGER: Do not touch the transfer switch until ALL power is disconnected. Shocks, burns, or death may result from high voltage.

CAUTION: Only personnel who are familiar with the power distribution system and this manual should be allowed to inspect or perform maintenance on the transfer switch.

Preventive maintenance

The following checks should be preformed as part of routine maintenance:

•A transfer test of the transfer switch should be preformed every week.

•The transfer switch should be kept clean of dust and moisture. DO NOT USE A BLOWER TO CLEAN the switch or the inside of the enclosure. Always use a clean cloth or vacuum to prevent debris from lodging in the switching mechanism.

•Check all wiring connections.

•Visually inspect the contacts for surface deposits and pitting. This inspection should be preformed annually.

Transfer Test

After installation, and each week thereafter, check the operation of the transfer switch by performing a manual and an automatic transfer.

Manual Test

WARNING: Disconnect the emergency and normal power sources before transferring with the handle. Manual operation is only for testing the mechanical operating mechanism or switching when there is a control problem.

Manual operation of the transfer switch is performed by sliding the square notch at the end of the handle onto the end of the square bar on the left side of the switch. Push the handle up to transfer to the normal source (A). To transfer the switch to the emergency source (B) insert a screw driver in the TRIP hole to put the switch in the neutral position. Then push the handle up and insert a screw driver into the SELECT hole to transfer the switch to the emergency source.

CAUTION: Do not leave the handle on the square bar. The handle prevents closure of the cabinet door and may cause damage to or prevent emergency operation of the transfer switch.
