WARNING
Live parts.
Electric shock hazard! Explosion
hazard! Risk of burns!
Ignoring this message may
lead to
serious injuries
or
death
. Connecting and
disconnecting only by qualified and authorised
personnel in zero-potential state and in a non-
explosive environment. Use a ground connection.
Avoid electrostatic charge. Use only Ex approved
and certified cable glands which are suitable
for the used cable, type of explosion protection,
ignition protection, degree of protection and the
ambient temperature range.

WARNING
Electrostatic charge. Explosion hazard!
Ignor-
ing this message may lead to
serious injuries
or
death
. To avoid electrostatic charge: use internal
or external ground connection.
Belt alignment switches should be installed at both sides of the con-
veyor belt close to the deflection and drive pulleys. In the case of very
long conveyor systems, further belt alignment switches must be in-
stalled. Mount with usual operation temperature.

Electric shock hazard! Explosion haz-
ard!
Ignoring this message may lead to serious
injuries or death. The enclosure cover must not
be damaged. The enclosure cover must be closed
tightly. Observe the tightening torque.

WARNING
Missing protective conductor connection leads to
short circuit.
Electric shock hazard!
Ignoring this
message may lead to serious injuries or death.
Connect protective conductor. Protective conduc-
tors may be connected by qualified and author-
ized personnel only.

WARNING
In case of overloaded contacts too high operation
temperatures.
Explosion hazard! Risk of burns!
Ig-
noring this message may lead to serious injuries
or death. For short-circuit protection use fuse
size 2 A, 4 A or 6 A (gG/gN).
Observe permitted
ambient temperatures.
NOTICE
Incorrectly aligned belt alignment lever.
Material
damage!
Only in case of failure may the belt-
alignment roller roll with the belt. The distance
between the belt alignment roller and the belt
edge must be 10-20 mm. The belt edge must
actuate the belt alignment roller in the belt align-
ment roller's lower part.
N.B.
Only authorized personnel are allowed to carry out mounting, electri-
cal connection and start-up. If the connection is in an explosive area,
the connection cable has to be connected in an enclosure which com-
plies with the requirements of an approved ignition protection degree
according to EN 60079-0, par. 1. Mounting must be carried out at usual
operation temperature. Any mounting position is possible.
EN 60079-14 has to be applied for the installation of electrical equip-
ment in explosive areas. The ATEX test certificate and the special con-
ditions therein have to be observed.
Reconstruction and alterations to the switch which might affect the
safety function are not allowed. The described products have been de-
veloped in order to assume safety functions as a part of an entire plant
or machine. A complete safety system normally covers sensors, moni-
toring modules, indicator switches and concepts for safe disconnec-
tion. For the integration of the safety switch into the entire system, the
control category determined in the risk assessment must be strictly
observed and respected. Therefore, a validation according to DIN EN
ISO 13849-2 or DIN EN 62061 is necessary.
Furthermore, the Perfor-
mance Level according to DIN EN ISO 13849-1 and SIL CL Level ac-
cording to DIN EN 62061 can be lower than the single level because of
the combination of several safety components and other safety-relat-
ed devices, e.g. by serial connection of switches.
It is the responsibility of the manufacturer of a plant or machine to
guarantee the correct general function. We reserve the right to make
design changes in line with technological progress. New claims for
guarantee, warranty or liability cannot be derived from this document
beyond the general terms and conditions of delivery.
