Additional requirements for the servo drives
concerning the UL approval
This chapter gives further information concerning the UL approval of the C 1-02, C 1-05 and C 1-08.
9.1
Circuit protection
In case of a required UL-certification the following data for the main fuse are to be considered:
Listed Circuit Breaker according to UL 489, rated 277 Vac, 16 A, SCR 10 kA
9.2
Wiring and environment regards
Use 60/75 or 75°C copper (CU) wire only.
The terminal tightening torque is 0.22...0.25 Nm.
To be used in a Pollution Degree 2 environment only.
9.3
Motor temperature sensor
Motor overtemperature sensing is not provided by the drive according to UL.
When a UL-certification is required, then in order to prevent motor overtemperatures the servo drives may only be operated in
connection with motors that are provided with an integrated motor temperature sensor. The sensor has to be connected to the
servo drive and the temperature monitoring has to be activated accordingly on the software side.
