7.3 Power Module Shutdown

When a power module needs to be removed from service, an Alpha APP60-S Service

Power Supply is recommended as an alternate non-standby power source to prevent

interruption to the cable plant. Note: When powering down a module, always switch the

battery breaker OFF before removing AC, otherwise the module will transfer into inverter

operation.

Procedure

1. Plug the APP60-S "Jones" connector into the SPI (Service Power Inserter).

2. Plug the APP60-S power cord into the enclosure's convenience outlet. Switch the

APP60-S ON. Note: Verify that the 30 / 60 VAC selector is in the desired position.

3. Toggle the switch on the SPI from "ON" to "ALT".

4. Switch the battery breaker on the side panel of the XM Series module OFF.

5. Unplug the XM Series module's power cord from the enclosure's convenience outlet.

6. Wait approximately 1 minute for the module's capacitors to fully discharge.

7. Remove the cables from the module's side panel connectors.

8. Carefully slide the power module out of the enclosure. CAUTION: The ferroresonant

transformer generates heat and may cause burns if handled with bare hands.

9. Reverse this procedure, when re-installing a module. Always test the power module

before toggling the SPI's switch from "ALT" to "ON".
