Installation, mounting, dismantling
Mount the emergency pull-wire switches for one-side actuation
ZS 71 ... according to the instructions and pretense the wire accord-
ingly (see »Mounting without compensation spring«, »Mounting with
compensation spring«, »Configuration of switch cam«).
To detect correct mounting:
1. Remove enclosure cover.
2. Tense the wire so that the switch cam is in middle position
(position B).

WARNING
If the connection cable blocks the mechanics, this
can lead to a malfunction of the device. Risk of
injury! Use the mounting clips in the device to lay
the cable. The routed cables must neither block nor
touch the actuating lever nor the reset lever.
Before mounting the pull-wire, remove the red PVC sheath from the
the pull-wire in the clamping range of the pull-wire (see »Mounting
notes wire thimbles«)! After fitting the wire, pull strongly on it several
times, as the pull-wire and the wire thimble will deform. Subsequently,
retense the wire using the DUPLEX wire clamp, eye-bolt or tensioner.
Mount the wire supports every 3 m. Install the wire supports in one
line in order to avoid stronger friction and to secure a proper function
of the tension springs.

Application and operation

=
WARNING
Live parts. Electric shock hazard! The enclosure
cover must not be damaged. The enclosure cover
must be closed tightly. Observe tightening torque.
=
WARNING
Incorrectly installed wire installations can lead to a
malfunction of the device. Risk of injury! Observe
the specified distances for wire support. Observe
maximum actuating forces for the levers. Observe
country-specific standards and directives.
=
WARNING
Missing protective conductor connection leads
to short circuit. Electric shock hazard! Connect
protective conductor. Protective conductors may
only be connected by qualified and authorized
personnel.
=
CAUTION
High temperatures. Risk of burns! For short-cir-
cuit protection use appropriate fuse size (see
technical data). Observe permitted ambient
temperatures.
N.B.
The electrical connection may only be carried out by authorised per-
sonnel. Any mounting position is possible. Reconstruction and alter-
ations at the device - which might affect the safety function - are not
allowed. The described products were developed in order to assume
safety functions as part of an entire plant or machine. A complete
safety system normally covers sensors, monitoring modules, indicator
switches and concepts for safe disconnection. For the integration of
the device in the entire system: strictly observe and respect the control
category determined in the risk assessment. Therefore, a validation
according to EN ISO 13849-2 or EN 62061 is necessary. Furthermore,
the Performance Level according to EN ISO 13849-1 and SIL CL Level
according to 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 sensors. It is the responsibility
of the manufacturer of a plant or machine to guarantee the correct
general function. Subject to technical modifications.

Maintenance and troubleshooting

=
WARNING
Live parts. Electric shock hazard! Do not repair
defective or damaged devices. Replace them.
Alternative: Repair of defective device by trained
personnel in agreement with steute and with
steute spare parts.
=
WARNING
Live parts. Unsuitable greases or lubricants can
lead to functional failure and loss of the protec-
tion class. Electric shock hazard! Do not use any
greases nor lubricants.
With careful mounting as described above, only minor maintenance is
necessary. We recommend a routine maintenance as follows:
1. Check pull-wire function.
2. Remove dirt.
3. Check sealing of the cable or conduit connections.

WARNING
Live parts. Electric shock hazard! When cleaning:
observe applicable degree of protection.
