3.3.1
Mount the safety light curtain in the explosion-proof enclosure (only if the safety light curtain is
used in North America)
NOTE
If the device in pre-mounted condition has been purchased, please skip this section.
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 devices with a resolution of 30 mm are suitable for mounting in the explosion-
proof enclosure. Follow the instructions in the underlying operating instructions for the
C4000 Fusion safety light curtain to configure the receiver light curtain to 30 mm opti‐
cal resolution prior to installing 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.
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.
