The RL1, RL2 and RL3 relay digital outputs of the CIR11 board
the operation status of the UR11 and the alarm and fault conditions of the temperature. The NO position
indicates that the UR11 is under regular operation and the NC position indicates a fault/alarm situation. Refer

DIP
SWITCH S1
The XC3R, XC3S, XC3T connectors located in the CIR11 board receive the NTCs signals that monitor the
heatsink temperatures.
The CIR11 board sets the rated operation voltage of the UR11 through the DIP switch S1. The 400 V model
(UR111140T4SZ) can be set to four different voltage levels: 380 V, 400 V / 415 V, 440 V / 460 V and 480 V
