amplifier modules without first turning off the power to
the power chassis and all related external power supplies.
Failure to observe this warning could cause injury or
damage to your equipment.

Removing Amplifier Modules

CAUTION:
electrostatic discharge (ESD) while you are handling or
storing them. Adept recommends using an antistatic
ground strap on your wrist when handling modules.
1. Turn off the PA-4 power chassis and the SmartController.
2. Note the location of any cables connected to the module, then disconnect them.
3. Loosen the captive screws at the top and bottom of the module.
4. Using both the top handle and bottom handle, pull the module straight out of the
chassis. Remove the module from the chassis and store it in a safe place.

Installing Amplifier Modules

1. Turn off the PA-4 power chassis and the SmartController.
2. If the slot has a blank panel installed, loosen the captive screws at the top and
bottom of the panel and remove it.
3. Verify that the intended slot for the module is open to accept the module.
4. Align the module with the card guide slots at the top and bottom of the card cage.
Slide the module in slowly. Apply straight-forward pressure to the top and
bottom handles until it is firmly seated in the rear power connector and the face of
the module is flush with the other modules.
5. Do not use excessive pressure or force to engage the connector. If the board does
not properly connect with the rear power connector, remove the module and
inspect the connector and guide slots for possible damage or obstructions.
6. Tighten the captive screws at the top and bottom of the module.
NOTE: There is an interlock circuit that prevents enabling power if the
amp module screws are not tightened securely. This also applies to any
blank panel cover(s).
WARNING:
the power chassis. Do not attempt to operate the PA-4
without blank panel cover(s) installed in any unused
slots.
