Cautions for UL and cUL
(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.
d)
Drive has no provision for motor over temperature protection. Motor over temperature protection is required at end application.
e)
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.
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)
Drive has no provision for motor over temperature protection. Motor over temperature protection required at end application.
h)
Use 60/75ºC CU wire only.
i)
Tightening torque and wire range as shown in the table below.
