INSTALLATION
CA 441, CA 442 and CA 443 are extension modules to PC 441 and do not work stand alone.
Mount the controller
Mount the unit on a 35 mm DIN rail. The physical dimensions of the device is: 86 x 70 x 58 mm
(3.39 x 2.76 x 2.28 inch) (H x W x D). If it doesn't easily snap onto the rail, you can pull the small tab
at the bottom side of the unit, using a small screwdriver.
Make all connections
The terminals should be connected to power and sensors. See table for each device:
CA 441
Figure 1 Outer terminals for the CA 44X series.
Ensure that all power is off, and that all output devices to be connected to the controller also are
turned off before you connect anything!
The power must be DC between 9 and 34 volts. Figure 3 shows how to connect power and how to
connect a battery pack for uninterrupted operation.
For cables longer than 30 m extra surge protection should be mounted where needed.
