Presetting for approach radius SIN-9004 M
1. Align and fasten SIN-9004 M to the hinged guard as shown on
page 7 (note parallel screw-on surfaces)
2. Loosen screw (TX8) until the actuator tongue can be swivelled
without spring force.
3. Insert the actuator tongue into the mounted SIN until it comes
into contact with the head housing, the spring in the housing of
the SIN-9004 M must not be loaded.
4. Pull the actuator tongue out of the SIN head by swivelling the
guard 25 mm. (The head must still be equipped with an anti-ro-
tation device.)
5. Now tighten the screw with 1.5 Nm.
6. Open and close the guard completely, the round shaft of the
actuator tongue must only move in the spring bearing. The
shaft must not support itself on the housing and thus cause an
overload of the actuator tongue.
7. Check whether the actuator tongue moves into the SIN head
without collisions. Then check the opposite screw of for the
torque of 1.5 Nm.

In order to maintain the safety level, the actuators can only
•
be ordered with the belonging safety switch in one unit.
The availability of replacement actuators and keys ensures a
•
simple handling of safety guards. Therefore, replacement ac-
tuators and keys have to be securely monitored. The same
applies to keys for resetting the emergency release or escape
release function.
The safety switch must not be used as end stops.

The SIN safety position switch with escape release option
must be installed within the hazardous area. The escape re-
lease option can only be used in order to quit the hazardous
area in case of a system failure.
•
The escape release must be on the escape side. The escape
release must not be accessible from the outside.

Electrical connection
Electrical connection should only be carried out by authorised
technical personnel.
Wiring
1. Lift off the cover after loosening the 4 screws (TX10).
2. Remove press-out blank by screwing in cable gland, remove
plastic part.
3. Tighten the certified cable gland M20 x 1.5 in plastic with 6 Nm
for connecting thread and cap nut.
4. The electrical contacts of the switching elements have M3.5
screw connections. See chapter 5.1 "Circuit symbol and inter-
locking", p. 13 for contact assignments.
The connection requires a stranded flexible wire with ferrule
with a cross section of 0.34 – 1.5 mm². Stripping length 6 - 7
mm, tightening torque of the contact screws 0.8 Nm.
5. Put on the cover.
Important! The auxiliary release must point to closed. There
must not be any connection wires between the cover and the
enclosure. The tightening torque must be 80-90 Ncm.
