Sicherheitshinweise für die Installation nach UL
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 energy (i
current (I
) of the inverse−time current−limiting circuit breaker will be less
p
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.
