5.3.2 MOUNTING (DIN RAIL)
Mount the controller in a rain-tight protected location. Fasten a 7” length of EN 50022 DIN 3 rail (35 mm height X 7.5 mm
depth) to the surface where the controller will be mounted. Place the top of the controller down onto the top of the DIN
Rail. Lower bottom of controller into place until DIN latch catches.
5.3.3 WIRING
With the Case Controller unpowered, carefully route the power and communication wiring from the Valve Module to
the Case Controller. Use 22/2 shielded twisted pair (Belden 8723 or equivalent). Attach one end of the shield to earth
ground. Wire designations are located on the top of the Valve Module. Maximum torque on the screw terminals is 3.5 in.-lb.
Carefully tug the leads to ensure they are secure. Ensure that all wiring is properly fastened and away from sharp edges or
moving objects. Do not route the Valve Module wiring in the same conduit as 120VAC or greater. See the following figures.
Note: The Valve Module and Display Module (DM) will be on the same network back to the Case Controller. It
is acceptable to dual stake in the terminals.
