Electrical Installation
5.2.12 UL-compliant installation (in preparation)
Power terminals
Observe the following notes for UL-compliant installation:
• Use only copper cables with a rated thermal value of 75 °C.
• DRC uses cage clamp terminals
Short circuit
current rating
Suitable for use in current circuits with a maximum short circuit current of 200 000 A
eff
:
• DRC, the max. voltage is limited to 500 V.
Branch circuit
protection
Integral solid state short circuit protection does not provide branch circuit protection.
Branch circuit protection must be provided in accordance with the National Electrical
Code and any additional local codes.
The table below list the permitted maximum fusing.
Motor overload
protection
DRC is provided with motor overload protection with a trip current adjusted to 150% of
the rated motor current.
Ambient
temperature
DRC is suitable for an ambient temperature of 40 °C, max. 60 °C with derated output
current. To determine the output current rating at temperatures above 40 °C, the output
current should be derated by 3.0% per K between 40 °C and 60 °C.
