Considerations

Wiring

HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH

• Apply appropriate personal protective equipment (PPE) and follow safe

electrical work practices. See NFPA 70E, CSA Z462 or NOM-029-STPS.

•

This equipment must only be installed and serviced by qualified

electrical personnel.

•

Turn off all power supplying this equipment before working on or inside

equipment.

•

Always use a properly rated voltage sensing device to confirm power is

off.

• Replace all devices, doors and covers before turning on power to this

equipment.

•

This equipment must be effectively grounded per all applicable codes.

Use an equipment-grounding conductor to connect this equipment to the

power system ground.

Failure to follow these instructions will result in death or serious injury.

The recommended conduit entry is at the bottom or either side of the device

enclosure. Use a conduit seal that is appropriate for the enclosure rating.
