MOUNTING AND ELECTRICAL CONNECTIONS - BOX VERSION
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 to the bottom of the box
for power connections (Figure 2). 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 cable gland at wire entrance to maintain the
same protection level as the unit.
Secure the back of the unit to the wall using the holes or by the enclosed
brakets.
Connect the tri-polar mains wire to the power supply terminal board (minimum
1.5 mm2 per pole) and secure it with the specific cable gland.
Power the unit and, next, connect the red and black tipped faston wires to the
two 12 V 7 Ah max lead buffer battery power supply, housing them in the upper
part of the cabinet (bottom).
