5 A) To replace the cover, while holding the cover at an angle, gently move the top rear edge of the cover over the top of the control unit and match up the grooves where the top edge of the cover meets the backplane. Gently push the edge into place.
B)Lower the bottom of the cover until it is secured in place.
Replacing System Modules
1 A) To power down the control unit, pull out the main circuit breaker.
On a PARTNER Plus 220V system, move the on/off switch to the “off” position (“O”).
B)To remove the cover, place one hand on the handle on the bottom front of the cover and place your other hand on the top of the cover.
C)Gently pull the cover up from the bottom and tilt it towards the top until it detaches from the backplane.
2 A) Check the slack in the wires. If there is not enough slack to remove the module without pulling
the line and extension cords free, label and disconnect the wires before continuing with Step 2B.
B)Place one hand on top of the module. With your other hand, grip the plastic bracket on the bottom front of the module, and use your middle finger to hold down the locking tab just below the bracket. Pull out the old module.
C)To insert the replacement, hold down the locking tab and align the dovetail guides on the sides of the modules. Push slowly but firmly until
the module locks into place with two snaps, and is attached to the rear of the backplane and held in place by the locking tab. Do not force the module. If it does not insert easily, remove the module, clear any obstruction, and reinsert.
