Power Cable and Control Wire Terminals
Loose connections in power circuits can cause overheating that can lead to
equipment malfunction or failure. Loose connections in control circuits can
cause control malfunctions. Loose bonding or grounding connections can
increase hazards of electrical shock and contribute to electromagnetic
interference (EMI). Check the tightness of all terminals and bus bar
connections and tighten securely any loose connections. Replace any parts
or wiring damaged by overheating, and any broken wires or bonding straps.
Refer to the User Manual for torque values required for power cable and bus
hardware connections.
Coils
If a coil exhibits evidence of overheating (cracked, melted or burned
insulation), it must be replaced. In that event, check for and correct
overvoltage or undervoltage conditions, which can cause coil failure. Be
sure to clean any residue of melted coil insulation from other parts of the
device or replace such parts.
Batteries
Replace batteries periodically as specified in product manual or if a battery
shows signs of electrolyte leakage. Use tools to handle batteries that have
leaked electrolyte; most electrolytes are corrosive and can cause burns.
Dispose of the old battery in accordance with instructions supplied with the
new battery or as specified in the product manual.
Pilot Lights
Replace any burned out lamps or damaged lenses. Do not use solvents or
cleaning agents on the lenses.
