General markings:
l
Use 60/75 °C or 75 °C copper wire only.
Maximum ambient temperature 55 °C, with reduced output current.
l
Markings provided for the supply units:
Suitable for use on a circuit capable of delivering not more than 5000 rms
l
symmetrical amperes, 480 V max, when protected by K5 or H Fuses (400/480 V
devices).
Alternate - Circuit breakers (either inverse-time or instantaneous trip types) may
l
be used in lieu of above fuses when it is shown that the let-through energy (i
and peak let-through current (I
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
l
rating of the drive, multiplied by 300 % .
Markings provided for the inverter units:
The inverter units shall be used with supply units which are provided with
l
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
l
the motor.
The devices are not provided with overspeed protection.
