SECTION 5 MAINTENANCE
5.1 General
5.2 Cleaning
Periodically, remove the cover from the power source and blow accumulated dust and dirt from the air passages and inte-
rior components by using clean, dry low pressure air. The frequency of cleaning required depends upon the environment
in which the power source is used.
It is imperative that all air passages be kept as clean as possible in order to allow adequate air flow to provide proper cool-
ing.
After cleaning with low pressure air, check for and tighten any loose hardware, including all electrical connections. Check
for frayed and/or cracked insulation on all power cables and replace if necessary.
CAUTION
WARNING
If this power source does not operate properly, stop work immedi-
ately and investigate the cause of the malfunction. Maintenance
work must be performed by an experienced person, and electrical
work by a trained electrician. Do not permit untrained persons to
inspect, clean, or repair this power source. Use only recommended
replacement parts.
WARNING
BE SURE THAT THE BRANCH CIRCUIT OR MAIN DISCONNECT SWITCH
IS OFF, OR ELECTRICAL INPUT FUSES ARE REMOVED, BEFORE AT
TEMPTING ANY INSPECTION OR WORK INSIDE THE POWER SOURCE.
PLACING THE POWER SWITCH IN THE OFF POSITION DOES NOT RE
MOVE ALL POWER FROM INSIDE THE POWER SOURCE.
FAILURE TO REPLACE WORN OR DAMAGED CABLES MAY RESULT IN
A BARE CABLE TOUCHING A GROUNDED OBJECT. THE RESULTING
ELECTRICAL ARC MAY INJURE UNPROTECTED EYES AND WILL PRES
ENT A SERIOUS FIRE HAZARD. BODY CONTACT WITH A BARE CABLE,
CONNECTOR, OR CONDUCTOR MAY RESULT IN SEVERE ELECTRICAL
SHOCK, CAUSING SERIOUS BURNS OR DEATH.
