Warnings!
General markings:
ƒ Use 60/75 °C or 75 °C copper wire only.
ƒ Maximum ambient temperature 55 °C, with reduced output
current.
Markings provided for the supply units:
ƒ 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).
ƒ 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
energy (i
2 t) and peak let−through current (I
p
) of the inverse−time
current−limiting circuit breaker will be less than that of the
non−semiconductor type K5 fuses with which the drive has been
tested.
ƒ Alternate − An inverse−time circuit breaker may be used, sized
upon the input rating of the drive, multiplied by 300 %.
Markings provided for the inverter units:
ƒ 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.
ƒ The devices are provided with integral overload and integral
thermal protection for the motor.
ƒ The devices are not provided with overspeed protection.
