Warnings!

These devices are suitable for field wiring.

Intended for use with 75 °C wire.

Intended for use with copper conductors only.

Suitable for use in a surrounding air temperature of 45 °C, and
– additionally 60 °C when de−rating rules are followed.

Hot surface. Risk of burn.

Should this device be mounted on a motor, the combination needs to be
suitable for the type rating.

The supply terminals are to be tightened to:
– For model suffix’s 0.75 – 2.2 kW tighten to 4.4
− 5.3 lb−in.
– For model suffix’s 3.0 – 4 kW, tighten to 7 lb−in.

These devices are suitable for use on a circuit capable of delivering not more
than 200 000 rms Symmetrical Amperes, 480 V maximum
– When protected by CC, R, T, or J class fuses or
– When protected by a circuit breaker having an interrupting rating not less
than 200 000 rms symmetrical amperes, 480 V maximum.

Use fuses and circuit breakers only.

Integral solid state short circuit protection does not provide branch circuit
protection. Branch circuit protection must be provided in accordance with
the National Electrical Code and any additional local codes.

The opening of branch circuit protective devices may be an indication that a
fault current has been interrupted. To reduce the risk of fire or electric shock,
current carrying parts and other components, the controller should be
examined and replaced if damaged.

These devices provide overload protection rated for 125 % of the rated FLA.
CAUTION!

Risk of electric shock. Please allow 180 s for the internal capacitors to
discharge.
