DANGER
Risk of ignition or explosion
b
Use fixing screws with a yield point of at least 640 MPa to attach the cover to the
explosion-proof enclosure.
NOTE
Only 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-
proof enclosure.
2. Attach the swivel mount brackets to the upper and lower end caps on the safety
light curtain.
3. 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.
4. Using the fixing screws supplied, attach the swivel mount brackets to the mount‐
ing holes provided in the explosion-proof enclosure.
5. 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.
