Removing and Installing Amplifier Modules
The Adept PA-4 power chassis is shipped from the factory with the amplifier modules
installed in the chassis. Any unused slots are filled with blank covers. Normally you will
not need to remove the amplifier modules. If you do need to remove and re-install a
module for some reason, follow the instructions below. The four slots in the chassis are not
interchangeable, some slots have special control signals. The amplifier modules are
factory-installed in the correct slots. Contact Adept Customer Service if you need to
relocate any modules.
WARNING: Do not attempt to install or remove any 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
1. Turn off the power chassis and the Adept MV controller.
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.
CAUTION: You must take precautions to prevent amplifier modules
from being exposed to electro-static discharge (ESD) while you are
!
handling or storing them. Adept recommends using an anti-static ground
strap on your wrist when handling modules.
Installing Amplifier Modules
1. Turn off the power chassis and the Adept MV controller.
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 ready 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.
It should not be necessary to use excess 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.
5. Tighten the captive screws at the top and bottom of the module.
WARNING: 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). There are dangerous voltages present inside the
power chassis, do not attempt to operate without blank panel cover(s)
installed in any unused slots.
