SAFETY SEGMENT
SECTION II: ELECTRICAL HAZARDS
A. Servicing with “Power Off”
For maximum safety, unplug the power cord from the wall
outlet before opening the vender door. This will remove
power from the equipment and avoid electrical hazards.
Service personnel should remain aware of possible hazards
from hot components although electrical power is off.
B. Servicing with “Power On”
Some service situations may require access with power on.
Only fully qualified service technicians should perform
power-on servicing. Particular caution is required in
servicing assemblies that combine electrical power and
mechanical movement. Sudden movement (to escape
mechanical action) can result in contact with live circuits
and vice versa. It is therefore important to maintain
maximum clearances from both moving parts and live
circuits when servicing.
WARNINGS:
1. ONLY FULLY TRAINED PERSONNEL SHOULD
ACCOMPLISH “POWER-ON” SERVICING.
SUCH SERVICE BY UNQUALIFIED
INDIVIDUALS CAN BE DANGEROUS.
2. LIGHTING CIRCUITS CAN BE HAZARDOUS.
ALWAYS DISCONNECT VENDER FROM THE
WALL OUTLET BEFORE REPLACING A BULB
OR SERVICING THE VENDER IN THAT AREA.
3. NEVER USE A HOSE, PRESSURE WASHER
OR ANY CLEANING METHOD THAT COULD
WET ELECTRICAL COMPONENTS. SEE
CLEANING SECTION OF MANUAL FOR
SUGGESTED CLEANING METHODS. IF
WATER CONTAMINATION OF ELECTRICAL
COMPONENTS IS SUSPECTED, USE QUALIFIED
ELECTRICAL TESTING EQUIPMENT AND TEST
METHODS TO ASSURE THAT VENDER IS NOT A
HAZARD BEFORE APPLYING POWER FOR ANY
REASON.
