ambient temperature range of 32°F
to 104°F (0°C to 40°C).
For installation and maintenance,
3 ft (914 mm) clearance is required
in the front and rear of the unit. For
proper ventilation during normal
operation, leave 8 in. (203 mm)
clearance on the rear. No side

POWER WIRING AND
CONDUIT

When connecting wiring, follow the
local wiring regulations, and take the
environment situation into account.

NOTE : The conduit size and wiring
method must be in accordance with
all local, regional and national codes
and regulations, including NEC
ANSI/NFPA 70.

The maximum current for operating
modes, the recommended wire
sizes, and the recommended power
cables and plugs are listed in Tables
1 to 3, above, and are based upon

an

86°F (30°C) ambient temperature.

Lock-out and tag before
you begin

Ensure that the feeder breakers are
open and locked, and tagged to
prevent inadvertent operation by
unauthorized personnel.
