Faulty or improperly maintained equipment can cause
property damage, physical injury, or possibly death by fire or electrical
shock. Here is a list of some important items to check when troubleshooting or
maintaining equipment.
Stop operating IMMEDIATELY if equipment is
malfunctioning. Notify your supervisor of the malfunction. Do not perform any
further operations until the problem is corrected.
Do not perform any maintenance unless you are
qualified to perform such work. Only qualified personnel should install,
maintain, and repair the equipment.
Avoid live circuits. Disconnect the equipment from
the main electrical power source before working on the inside of the equipment.
Just turning of the equipment power switch does not shut of the power going to
the equipment. If external 115-volt power is used to energize a power supply contactor,
disconnect it as well. Use disconnect/lockout/tag procedures where possible.
Make test readings carefully. If necessary to take
test meter readings on live electrical equipment, be sure to wear insulating
gloves, use properly insulated test probes, and applies input voltage
momentarily to obtain the readings.
Maintain cables, grounding wire, connections, power
cord, and power supply in safe working order. Do not operate equipment in
faulty condition. Replace damaged cables.
Do not abuse the equipment. Protect the equipment
from heat, excessive wet conditions, oil or grease, corrosive atmospheres, and
inclement weather.
Replace parts only with manufacturer’s recommended
replacement parts. Do not substitute, modify, or use unauthorized parts. Use
fuses of proper rating as specified in the manufacturer’s manual. Read and
understand the operating instructions provided by the manufacturer of the
equipment before attempting repairs.
Keep all protective devices and covers in position.
They are designed to protect personnel and equipment.
