Cooper Bussmann Power Module™ Switch
Maintenance
To help assure proper operation of the Cooper Bussmann Power Module Switch, all
components should be tested and inspected on an annual basis by a qualified
person. Cooper Bussmann suggests the following*:
Testing
• Performing these steps helps verify the Power Module Switch is properly operating. If
you are unable to successfully completed these steps, contact Cooper Bussmann.
• Make sure the system is energized and turned ON.
• Activate the fire alarm system contacts for shunt trip. (A fire alarm technician may be
required for this step.) If the Power Module Switch has a key test switch, use it to shunt
trip the unit without activating the fire alarm system.
• Shunt trip will energize the fire alarm isolation relay and close contact points 4 and 7.
• Closuring relay points 4 and 7 will energize the shunt trip coil, opening the switch
contacts, and actuating the switch and handle into the TRIP position.
• Verify that power is disconnected and the handle is in the TRIP position.
• Move the handle position to RESET, then allow handle to assume the OFF position.
• Move the handle from the OFF position to the ON position.
• Verify that power is restored.
Inspection
• Keep switch exterior and interior clean. Always follow prevailing safety rules when
servicing this product throughout the year.
• Periodically check lug torque values and keep them in specification. The chart on page 6
contains the torque values for the various switch amp ratings.
• Preventative maintenance should include a thermal-scan to uncover any portion
generating excessive heat that indicates an underlying problem.
• Any unexpected temperature increase, not related to load variations or ambient
temperature could signal a lug torque issue.
• Maximum temperature at any lug should never exceed 75°C under any operating
condition or load.
* Before performing any inspection or testing, notify affected building occupants that the elevator is
being taken out of service.
Electrical equipment may contain hazardous voltages. These
can cause electrical shock, burn or death.
Only qualified personnel should perform procedures involving
electrical equipment. Always properly ground equipment and
lockout electric power (de-energize) before accessing electrical
equipment and enclosures. All deadfronts and other shielding
must be in place before energizing this disconnect switch.
Take note of and follow all safety instructions in this Instruction
Leaflet.
