SAFETY INFORMATION 2

DANGER
Risk of ignition
Failure to observe this information could result in a risk of ignition.
bThe type label on each individual explosion-proof enclosure contains information
on the device's hazardous area class and group. Every device that penetrates the
explosion-proof enclosure must be suitable for the environment in which the ex‐
plosion-proof enclosure is installed with regard to its hazardous area class and
group.
bFor North American installations:
 Any conduit openings that are not in use must be sealed. Sealing fittings must
turn at least five (5) full revolutions and be at least 3.175 mm thick (1/8 of an
inch).
bConduit sealing fittings must be applied in each installed conduit run (located a
maximum of 457 mm (18 inches) away from the explosion-proof enclosure) in or‐
der to comply with the provisions of the most recent version of the National Elec‐
trical Code, Article 501.15 and/or 502.15, and all other applicable regulations.
bFor installations where the use of a cable gland is required, the cable gland must be
certified for 'd' and 'tb' locations.
The cover can be removed for maintenance in all approved classes, groups, and zones
except tb/IIIC, tb/IIIB, and tc/IIIC locations.
2.2 General safety notes
DANGER
Risk of ineffectiveness of the protective device
Persons or parts of the body to be protected are not recognized in case of non-observ‐
ance.
bPay particular attention to all warnings in the operating instructions.
WARNING
Risk of ineffectiveness of the protective device
Please observe the following information to ensure that you are using the explosion-proof
enclosure safely and correctly.
bNational and international regulations and guidelines must be observed when
mounting, using, and commissioning electrical devices as well as when carrying
out regular technical inspections in explosive environments. Article 500 of the Na‐
tional Electrical Code and ATEX Directive 2014/34/EU shall apply in particular. Manu‐
facturers and operators of machines using safety light curtains are responsible for
ensuring that all applicable safety regulations and guidelines are complied with.
bThese operating instructions must be made available to the operator of the ma‐
chine on which the explosion-proof enclosure is used. Qualified safety personnel
must instruct the operator in how to use the device. The operator must also be
directed to read and follow the operating instructions.

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
bAlways switch off the power supply before removing the cover or disconnecting a
connecting cable from the device.
bEnsure that all electrical connections to the device or the connection are protec‐
ted.
bThe IP enclosure rating of the connections, and therefore also of the device, is on‐
ly guaranteed if the connections are protected. Otherwise, foreign objects may get
into the terminal compartment, which may cause an explosion when the device is
next switched on.
bIt is imperative that suitable technical measures are used to guarantee the IP en‐
closure rating of the connecting cables.
DANGER
Risk of ignition or explosion
bDisconnect the power supply before opening the explosion-proof enclosure to
avoid igniting hazardous atmospheres.
bIf you have to remove the cover during the electrical installation process, make
sure that the joints and o-ring are clean and undamaged before refitting the cover.
bDo not reconnect the power supply until you have completed the electrical instal‐
lation process and secured the covers as specified.

5 Aligning the sender and receiver
After mounting and electrical installation, the sender and receiver must be aligned with
each other.
DANGER
Dangerous state of the machine
bMake sure that the outputs of the safety light curtain have no effect on the ma‐
chine during the alignment process.
NOTE
Use the optional alignment bracket if the alignment cannot be adjusted when mounting
the safety light curtain directly.
Aligning using the alignment bracket
The alignment bracket can be used to adjust the safety light curtain as follows:
–Rotate (± 45°)
figure 14: Rotating with the alignment bracket
Aligning the sender and receiver with one another
How to align the sender and receiver using the alignment bracket:
bPay attention to the mounting heights of the sender and receiver. Both devices
must be mounted at the same height.
bProvide a rectangular protective field. The sender and receiver must be mounted
parallel to one another.
bSwitch on the power supply to the safety light curtain.
bRotate the sender to align the sender to the receiver.
bRotate the receiver to align the receiver to the sender.

bFollow the alignment instructions in the underlying operating instructions.
bOnce the sender and receiver are aligned correctly, secure the components in the
alignment brackets with a torque of 28 to 28.5 Nm.
bSwitch the power supply off and then on again.
