STANDARD PREVENTIVE MAINTENANCE PROCEDURES
These preventive maintenance procedures cover standard pro-
cedures for the console preventive maintenance requirements.
Read through them before beginning the procedure.
Checking Connections
Check all signal wiring, power and ground connections within
the cabinet to verify their integrity. When checking connec-
tions, always turn a screw, nut or other fastening device in the
direction to tighten only. If the connection is loose, it will be
tightened. If the connection is tight, the tightening action will
verify that it is secure. There must not be any motion to loosen
the connection.
NOTE: Power to the cabinet must be off while performing this pre-
ventive maintenance task.
1. Check and verify that all phase, neutral and grounding
conductor connections on the power entry panel are secure.
2. Check and verify that all other power connections within
the cabinet, including connections to the power supplies are
secure.
3. Check and verify that all field wiring connections to the
communication modules are secure.
Cleaning the Monitor
To clean the monitor window, remove dirt, finger prints or
grease with a commercial glass cleaner and a soft lint-free
cloth.
WARNING
Never clean electrical parts or components with the power on.
Doing so exposes you to a fatal electrical shock hazard.
Wear eye protection whenever working with cleaning solvents.
When removing solvents from printed circuit boards using
compressed air, injury to the eyes could result from splashing
solvent as it is blown off the printed circuit board.
AVERTISSEMENT
Il ne faut jamais nettoyer des piècesou des composants élec-
triques lorsqu'ils sont sous tension. Ceci présente un risque
d'électrocution fatale.
Portez toujours des lunettes de protection lorsque vous uti-
lisez des solvants de nettoyage. L'aircomprimé servant à
enlever le solvant des cartes de circuits imprimés provoque
des éclaboussures qui risquent d'atteindre les yeux.
