5 Repair and Disassembly Plug-in Modules
108
WARNING When you disassemble/assemble a plug-in module a patient leakage current test must be performed
before it is used again for monitoring.
To disassemble a plug-in module:
Remove the front housing.
– Place the module on a flat surface and insert a card (similar to a credit or cheque type card) into
one side of the module to disengage the 2 tabs securing the front housing to the module housing.
– Pull the edge of the front housing away from the module housing.
– Carefully turn the module over so the free edge does not reengage and repeat the first two steps
on the other side of the module. The front housing should now be free of the module housing.
To reassemble a plug-in module:
Snap-fit the front housing onto the front of the module case so the openings in the front housing
match the LEDs and keys.
