26 Condair CDC, CDC-NA, CDC-ST and CDC-SL
2.8.3 Connecting the CDC or CDC-NA to the Condair RS/RS OC
1. Connect the CDC (signal Y1) to the corresponding terminals on the driver board of the Condair RS/
RS OC (ROW) according to the following diagram.
Note: The voltage supply of the CDC is established via the terminals "V+" and "GND" of terminal
block "X8" or via an external 24 V AC/DC voltage supply.
Note: In case of humidity control with limitation of the supply air humidity, a second CDC duct humid-
ity sensor (signal Y2) is to be connected according to the wiring diagram below.

Connect the CDC-NA (signal Y1) to the appropriate terminals of the terminal block "XE2" of the
Condair RS/RS OC (NA) according to the following diagram.
Note: The voltage supply of the CDC-NA is established via the terminals "Control Signals (V+)" and
"Control Signals (GND)" of terminal block "XE2" or via an external 24 V AC/DC voltage supply.
Note: In
case of humidity control with limitation of the supply air humidity, a second CDC-NA duct
