First mount the C4000 Select safety light curtain in the explosion-proof enclosure
using the two swivel mount brackets supplied. The swivel mount bracket makes it
possible to rotate the sender and receiver around the axis of the device and to
align them accurately.
2. Install the cable glands if necessary.
3. Secure the handles supplied onto the enclosure cover.
4. Mount the safety light curtain in the explosion-proof enclosure onto the machine.
The explosion-proof enclosure can either be attached directly or using the align‐
ment bracket (available as an accessory, see "Ordering information, accessories",
page 31).
NOTE
bRead this section completely before mounting the safety light curtain.
bRead the section "Aligning the sender and receiver", page 22.
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
Skip this chapter if you have purchased the safety light curtain in pre-mounted condi‐
tion.
DANGER
Risk of ignition or explosion
bUse 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.

6. Align the safety light curtain in the explosion-proof enclosure so that it meets the
following criteria:
°Each rib in the window on the cover must cover no more than one optical
lens.
°Depending on the protective field height, the first rib on the side of the con‐
nection must cover the following optical lenses:
Protective field height Optical lenses covered
600 mm Tenth optical lens
900 mm Second optical lens
1,200 mm Second optical lens
7. Turn the safety light curtain in the swivel mount brackets so that the front screen
of the safety light curtain faces the opening in the explosion-proof enclosure. The
infra-red rays must be able to pass through the window in the cover without ob‐
struction.
8. Tighten the screws used to secure the safety light curtain in the swivel mount
brackets with a torque of 2.5 to 3 Nm.
9. Guide the connecting cable through the 3/4" NPT opening. Make sure that the
thread for the 3/4" NPT opening is not damaged.
10. If a cable gland is required, follow the instructions to mount the gland, see "Mount‐
ing the optional cable gland", page 12.
11. Fit the cover to the explosion-proof enclosure using the supplied fixing screws and
washers. Tighten the fixing screws with a torque of 11.5 to 14.5 Nm.
NOTE
The washers must be used to obtain enclosure rating IP 66.
3.3.2 Mounting the optional cable gland
Depending on national regulations and requirements, a cable gland may have to be in‐
stalled. The cable gland is available as an accessory.
1. Guide the cable through the cable gland.
2. Screw the cable gland into the 3/4" NPT opening on the explosion-proof enclosure.
3. Pull the collar on the cable gland so that the cable is securely attached.
DANGER
Risk of ignition or explosion
bCheck the 3/4" NPT opening for damage to the thread.
bDo not use the device if the thread of the 3/4" NPT opening is damaged.
3.3.3 Mounting the handles onto the cover of the explosion-proof enclosure
1. Use the supplied M6 screws to secure the two handles onto the cover of the explo‐
sion-proof enclosure.
2. Tighten the screws with a torque of 4.5 to 5 Nm.

4 Electrical installation
4.1 Safety
In addition to the information in the underlying operating instructions, please observe
the following points when installing the electrics for the safety light curtain.
DANGER
Ignition Hazard
Failure to observe this information could result in a risk of ignition
bAlways switch the power supply off before disconnecting a connecting cable from
the device.
bEnsure that all electrical connections to the device or the connections are protec‐
ted.
bThe IP enclosure rating for the connections and therefore for the device is only
guaranteed if the connections are protected. Otherwise foreign objects can get in‐
to the terminal compartment. This can cause an explosion the next time the de‐
vice is switched on.
bIt is absolutely essential that you take technical measures to guarantee the IP en‐
closure rating for the connecting cables.
DANGER
Risk of ignition
Failure to observe this information could result in a risk of ignition.
bIf the safety light curtain is used in an environment classified as tb IIIC, tc IIIB or
tc IIIC the cover must not be removed, not even temporarily (e.g. for maintenance
purposes).
DANGER
Risk of ignition or explosion
bIf you have to remove the cover when working on the safety light curtain, make
sure that the joints and o-ring are clean and undamaged before refitting the cover.
DANGER
Risk of ignition or explosion
bDisconnect the power supply before opening the explosion-proof enclosure to
avoid igniting hazardous atmospheres.
bDo not reconnect the power supply until you have completed the electrical installa‐
tion.
