3. Mounting
3.1 General mounting instructions
1. Fit the emergency stop actuator in non-actuated condition by means
of the ELM mounting flange, align and tighten (max. 0.6 Nm)
2. Snap the EFR.1 or EFR spring elements in the middle position of the
ELM mounting flange (position 3).
3. The EMERGENCY STOP actuator is latched (i.e. mechanically fixed)
to the EFR 1 or EFR spring element by actuation. Unlatching by pulling
on the EMERGENCY STOP actuator retentions the spring element
and the EMERGENCY STOP is brought back to the ready position.
4. Snap the desired EF... contact elements onto the free positions to
the right and to the left (position 1 and 2) next to the EFR.1 or EFR
spring element.
5. Mounting of the securing plate with the EFR (not required with the EFR.1):

Installation of EFR discontinued for NDRZ... emergency
stop devices. Instead of the ELM mounting flange, the EFM
mounting flange is installed here. The relevant mounting
flange is included in the items supplied with the device head.
If using NDRZ... emergency stop devices with the PS116
position switch, the supplied EFM mounting flange must be
replaced with the EFMH mounting flange.
For position switch combinations, secure the position switch
to the EFMH mounting flange using the supplied screws and
tighten to a torque of 0.8 Nm. The washers are not required
for the PS116 position switch and have been left out.
The pre-mounted assembly group from EFMH and the
position switches are now mounted on the emergency stop
control panel in an unactuated state, aligned and screwed
tightly (max. 0.6 Nm).

4. Electrical connection
4.1 Important notes
The electrical connection may only be carried out by
authorised personnel in a de-energised condition.
At least one contact with positive break must be integrated
in the safety circuit.
After wiring, the contact elements must be cleaned
(i.e. remove excess cables etc.).
The fixing screws of the contact element must be tightened
with 0.8 Nm tightening torque.
4.2 Contact variants
The following contact variants can be combined together:
Screw or plug-in terminals:
- 1 x EF303 (1 NC / 1 NO) + 1x EF220 (2 NC) or
- 2 x EF303 (1 NC / 1 NO each contact element) or
- 2 x EF220 (2 NC each contact element)

5. Set-up and maintenance
5.1 Functional testing
The safety function of the safety components must be tested.
The following conditions must be checked and met:
• Correct fixing of the fitted component
• Check the integrity of the cable entry and connections
• Check the emergency stop command device for damage
5.2 Maintenance
A regular visual inspection and functional test, including the following
steps, is recommended:
• Check the correct fixing of the emergency stop command device and
the contact element
• Remove particles of dust and soiling.
• Check cable entry and connections.
Damaged or defective components must be replaced.
6. Disassembly and disposal
6.1 Disassembly
The safety switchgear must be disassembled in a de-energised
condition only.
• Disassembly of the EF... contact element(s).
• Actuate/snap in EDR emergency stop actuator
• Spread the spring (A) between the NDRR actuator plunger
and the EFR spring element by means of a screwdriver (B) or similar
(refer to drawing). The actuator jumps back into basic position.
• Snap off the EFR spring element, disassembly the actuating
head if necessary.
See the operating instructions of the position switch for the
contact variants and switch travel for position switch PS116.

6.2 Disposal
The safety switchgear must be disposed of in an appropriate manner in
accordance with the national prescriptions and legislations.
