Surge Module Removal & Replacement Instructions

Surge modules within the SPD may become damaged and require replacement. To remove and replace a surge module, refer to Figure 9 and proceed as follows:

1.Disconnect power to the SPD.

2.Open the door on the unit by loosening the two screws that secure the door latches in place. Slide the top latch upward and rotate it so that it no longer secures the door. Slide the bottom latch downward and rotate it so that it no longer secures the door.

3.Remove the two allen-head screws that secure the surge module to the chassis.

4.Pull the surge module out of the chassis.

5.Note the location and part number of each module removed as this information is not supplied elsewhere in the cabinet.

NOTE: Surge Modules should only be replaced with a new module having the same part number as the removed module.

6.Unpack and inspect the replacement surge module for damage. If the replacement module is damaged, contact APC Technical Support.

7.Align the replacement surge module with the mounting holes in the chassis. Install the two allen-head screws removed in step 3 and torque to 65 inch-pounds.

8.Power up the SPD and verify that the green LED is lit and that all alarms have cleared.
