Onl
y safety light curtains with a resolution of 30mm are suitable for mounting in the
explosion-proof enclosure.
1. Unscrew the fixing screws on the cover and remove the cover from the explosion-
pr
oof enclosure.
2. Attach the swivel mount brackets to the upper and lower end caps on the safety
light curtain.
3. Mount the mounting bracket onto the riser using the fixing screws supplied. Align
the mounting bracket with the two locating pins. Tighten the fixing screws with a
torque of 5 to 5.5Nm.
4. Secure the mounting bracket about halfway along the safety light curtain using
the two sliding nuts so that the riser is behind the safety light curtain. Insert and
hand-tighten the screws on the sliding nuts.
5. Position the safety light curtain in the explosion-proof enclosure so that the con‐
necting cable is at the same end of the explosion-proof enclosure as the 3/4" NPT
opening.
6. Using the fixing screws supplied, attach the swivel mount brackets and riser to the
mounting holes provided in the explosion-proof enclosure.
7. Tighten the fixing screws on the swivel mount brackets with a torque of 2.5 to 3
Nm. Too high a torque could damage the swivel mount brackets while too low a
torque does not provide sufficient protection against vibration.
