Mounting and electrical connections
After opening the transparent unit door, also open the front panel by rotating the black lock to
UNLOCK.
Disconnect the two wires that lead from the unit board (JP47 and JP51 connectors) to the
bottom of the box for power connections (see fig. 2.1.1). Close the front panel turning the lock to
LOCK.
Remove the 4 screws at the 4 corners of the box and remove the front part of the unit box.
Holes can now be drilled in the back of the box for wire passage.
We recommend you use an IP65 wire clamp at wire entrance to maintain the same protection
level as the unit.
Secure the back of the unit to the wall using the holes (D) or by the enclosed brakets.
