WARNING: Servicing energized industrial control equipment can be hazardous.
Severe injury or death can result from electrical shock, burn, or unintended
actuation of control equipment. Hazardous voltages may exist in the cabinet
even with the circuit breaker in the off position. Recommended practice is to
disconnect or lock out control equipment from power sources, and confirm
discharge of stored energy in capacitors. If it is necessary to work in the vicinity
of energized equipment, the safety related work practices of NFTA 70E,
Electrical Safety requirements for Employee Work places, must be followed.
CAUTION: The CMOS devices used on the control circuit boards can be
destroyed or damaged by static charges. If personnel will be working near static
sensitive devices, they must be appropriately grounded.
