INSTALLATION MANUAL

STEP 1
STEP 2
Install the back box onto the supporting beams in the
wall or ceiling. The back box can be installed in both
horizontal or vertical direction. Use the provided slots
for mounting the back box to the supporting beams.
Depending on the structural material the appropriate
fasteners shall be used.
Assemble the cable gland through one of the provided
knock-out holes in the back box, and provide the cable
through it. Loop the cable through the bracket on
top of the back-box, to avoid stress on the cable and
contacts. Make sure the cable gland is well tightened
to avoid any air-leakage through it.
