This equipment is capable of providing internal motor overload protection according to
UL508C. Take the following actions In order to comply with UL508C:
● Use UL/CSA-certified J-type fuses, overload circuit-breakers or intrinsically safe motor
protection devices.
● For each frame size A to C use class 1 75° C copper wire only.
● Install the converter with any external recommended suppressor with the following
features:
– Surge-protective devices; device shall be a Listed Surge-protective device (Category
– Rated nominal voltage 480/277 V
– Clamping voltage V
– Suitable for Type 1 or Type 2 SPD application.
– Clamping shall be provided between phases and also between phase and ground.
● Do not change the parameter p0610 (factory setting of p0610 = 12 means: the drive
reacts on a motor overtemperature with an immediate alarm and after a certain time with
a fault).
