To avoid mistakes, only specialists are permitted to set up, connect and put the devices into operation. The specialist must have expertise on
the ignition protection type intrinsic safety (Ex ia/ib) as well as all relevant regulations and provisions for operating materials in explosive
areas. The limit switch boxes are developed in compliance with the following harmonised standards:
EN IEC 60079-0:2018 (IEC 60079-0, Ed. 7.0)
EN 60079-11:2012 (IEC 60079-11, Ed. 6.0)
It is imperative to observe the following safety instructions prior to initial operation:
Failure to observe the safety instructions in these operating instructions and using or handling the device
improperly, releases us from any liabilty. Furthermore, the warranty for the devices and accessory components
will expire.
Check on the labelling, whether the existing device is suitable for your case of application.
Observe national regulations and provisions as well as the corresponding installation specifications.
Take suitable measures, to prevent unintentional activation or improper interferences with the device.
Remove any existing sealing plugs just before inserting the wires to avoid dirt in the housing.
Make sure the strain is sufficiently relieved on the connecting cables or lay them securely.
Check the approved conductor cross-sections as well as the approved tightening torques in the documentation for cable connections
Effectively protect the devices and cables against damages.
Avoid static charge on plastic devices and cables. Therefore, only clean the device with an anti-static or damp cloth.
Housing components made of metal must be included in the potential equalisation by means of appropriate assembly.
This device may only be operated in a fully assembled condition.
Never disconnect the connector cables while they have power.
Only connect the limit switch box to approved intrinsically safe circuits with EC type-examination certificate and do not exceed the
maximums of the respective sensor for Ui, Ii, Pi, Ci and Li.
Each box has a separate, intrinsically safe circuit inside the box. For 2 sensors we recommend one of the following 2-channel switch
amplifiers as the associated electrical equipment:
IFM, N0533A / P+F, KFD2-SR2-Ex2.W / Turck, IM1-22EX-R
5. Assembly on actuators
Using the enclosed mounting material, the modules can be quickly and easily assembled to the provided actuator according to VDI
(Association of German Engineers)/VDE (German Electrical Engineering Association) 3845. It can only be directly mounted to actuators with
a 80x30 mm hole pattern and a drive shaft height of 20 or 30 mm. The maximum drive shaft diameter is 32 mm. For all other actuators you
will need our adjustable height and width mounting bracket IMBHV.
1. Adjust your actuator to the final position, in which the groove of the drive shaft is parallel to the drive housing.
2. Attach the two included mounting screws to the actuator. They can be installed on either side.
3. Now place the box on the actuator and secure from the side with the two included point set screw. For a shaft height of 30 mm, remove
the shaft extension (SI-WV10) from the shaft.
4. Unscrew the four cover screws and open the housing. Make sure you do not unscrew the screws too far; they should remain in the
cover.
5. Insert the system cable into the housing through the cable gland and connect the individual wires to the terminal block. When doing so,
please refer to the terminal diagram on the respective data sheet or on the cover of the housing and connect the housing to the
equipotential bonding.
6. Close the housing using the cover. When attaching the cover, please make sure that the seal is correctly positioned and tighten the
cover screws.

6. Assembly on manual valves
The boxes can also be mounted to manually operated valves using our "MSH" assembly kit. It is important that your manual valve has a
head flange according to ISO 5211 and a threaded hole in the shaft. Please use the “MSH” instruction manual for detailed assembly
instructions.
