J Warnings!
ƒ Use Class 1 wire only.
ƒ Intended for use with 75 °C wire.
ƒ Intended for use with copper conductors only.
ƒ Suitable for use in a surrounding air temperature of 45 °C, and
– additionally 55 °C when de−rating rules are followed.
ƒ Hot surface. Risk of burn.
ƒ Should this device be mounted on a motor, the combination needs to be
suitable for the type rating.
ƒ The supply terminals are to be tightened to:
– For model suffix’s 371, 551, 751, 112, 152 tighten to 4.4 − 5.3 lb−in.
– For model suffix’s 222, and 302, tighten to 7 lb−in.
ƒ These devices are suitable for use on a circuit capable of delivering not more
than 200000 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 200000 rms symmetrical amperes, 480 V maximum.
ƒ These devices are suitable for motor group installation on a circuit capable
of delivering not more than 200000 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 200000 rms symmetrical amperes, 480 V maximum.
ƒ Use fuses and circuit breakers only.
ƒ 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.
ƒ 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.
ƒ These devices provide overload protection rated for 125 % of the rated FLA.
CAUTION!
ƒ Risk of electric shock. Please allow 180 s for the internal capacitors to
discharge.
