3.0 INSTALLATION
The status lamps are mounted via 4 off Ø7mm mounting holes on the base of each unit or alternatively the units
may be mounted via 6 off Ø11.5mm mounting holes on an optional backplate, details of the fixing centres can be
found in section 4.
Units may be mounted to vertical, horizontal or angled surfaces.
The direct mount fixing holes have been designed to accept an M6 screw or bolt. The backplate fixing holes have
been designed to accept an M10 screw or bolt.
Access to Terminals
Unscrew the 4 off M5 screws (4.0mm A/F hexagon key) holding the cover assembly to the base. Keep the screws
in a safe, accessible location if non-captive. Remove cover assembly to gain access to the interior.
Once termination is complete, carefully push the cover assembly back onto the base, avoiding damage to the
mating surfaces. Replace the 4 off M5 fixing screws (maximum torque 4Nm) into the holes in the cover assembly
and tighten evenly, ensuring the O-ring is correctly seated in its groove during re-assembly
