Wire Power Cables
For models in Explosive Atmospheres or Hazardous
(Classified) Locations only.
To connect an Explosive Atmospheres or Hazardous
(Classified) Locations model to a power source,
complete one of the following:
• Hard wire the equipment to a power source.
• Supply a plug, socket, and interlocking device that
meets the requirements of EN 60079-0 or UL 674.
NOTE: See Required Power and Plugs, page 17, for
power requirements. Install a branch circuit protective
device in each ungrounded phase.
A 15 ft (4.6 m) cable (either 3-conductor or 4-conductor)
is provided with models for Explosive Atmospheres or
Hazardous (Classified) Locations. Connect the cable
directly to a panel with branch circuit protection and an
electrical disconnect per local codes and regulations. If
additional length of cable is required, connect additional
cable through a junction box. Use the following table to
select the minimum cable wire gauge based on length:
NOTE: Ensure that the electrical disconnect (AA) is shut
off and locked out before wiring. See F
IG. 8.
