28 Condair CDC, CDC-NA, CDC-ST and CDC-SL
2.8.4 Connecting the CDC or CDC-NA to the Condair EL/EL OC
1. Connect the CDC (signal Y1) to the corresponding terminals on the driver board of the Condair EL/
EL 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.
