1.3 Precautions Concerning Compliance with UL and cUL Standards

(Standard to comply with : UL508C,CSA C22.2 No.14-05)
a) Maximum surrounding air temperature rating of 50ºC.
b) Solid State motor overload protection reacts with max. 150 % of FLA.
c) Suitable for use on a circuit capable of delivering not more than 100,000 rms Symmetrical Amperes,
240 Volts Maximum. For models 200V class.
Suitable for use on a circuit capable of delivering not more than 100,000 rms Symmetrical Amperes,
480 Volts Maximum.For models 400V class.
d) Drive has no provision for motor over temperature protection.
e) When protected by J, CC, G or T Class Fuses. or When protected by a circuit breaker having an
interrupting rating not less than 100,000 rms symmetrical amperes, 240 Volts maximum. For models
200V class.
When Protected by J, CC, G or T Class Fuses. For models 400V class.
f) 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.
g) Install device in pollution degree 2 environment
h) Branch circuit short circuit protection can use fuse or circuit breaker only. For models 200V class..
Branch circuit short circuit protection can use fuse only. For models 400V class..
i) Use 60/75ºC CU wire only.
j) Tightening torque and wire range as shown in the table below.
