Additional requirements to be fulfilled by the
servo positioning controllers for UL approval
This chapter provides further information concerning the UL approval of the C 3-05 and C 3-10 devices.
9.1
Mains fuse
In case of a required UL certification, the following data for the mains fuse must be complied with:
Listed circuit breaker in accordance with UL 489, rated 480Y/277 VAC, 16 A, SCR 10 kA
9.2
Wiring requirements and environmental conditions
Use 60/75 or 75°C copper (CU) wires only.
Tightening torque for the connectors: 0.22...0.25 Nm.
To be used solely in an environment of pollution degree 2.
9.3
Motor temperature sensor
The servo positioning controller is not equipped with an integrated motor overtemperature sensor system in
accordance with UL.
If a UL certification is required, the servo positioning controllers may only be used in connection with motors that are equipped
with an integrated motor temperature sensor in order to ensure protection against motor overtemperatures. The sensor must
be connected to the servo positioning controller and the temperature monitoring system must be activated accordingly via the
software.
