Use 60/75 °C or 75 °C copper wire only.
Maximum ambient temperature 55 °C, with reduced output
current.
Suitable for use on a circuit capable of delivering not more than
5000 rms symmetrical amperes, 480 V max, when protected by
K5 or H Fuses (400/480 V devices).
Alternate − Circuit breakers (either inverse−time, instantaneous
trip types or combination motor controller type E) may be used in
lieu of above fuses when it is shown that the let−through
2
energy (i t) and peak let−through current (I
current−limiting circuit breaker will be less than that of the
non−semiconductor type K5 fuses with which the drive has been
tested.
Alternate − An inverse−time circuit breaker may be used, sized
upon the input rating of the drive, multiplied by 300 %.
The inverter units shall be used with supply units which are
provided with overvoltage devices or systems in accordance with
UL840 2nd ed., Table 5.1.
The devices are provided with integral overload and integral
thermal protection for the motor.
The devices are not provided with overspeed protection.
