Prerequisite
The detector line must be switched off!
Install the radio gateway so that it is at any time easily accessible for battery exchange and for the
operation elements MC-Link connector, button and reed contact.
Pay attention to a correct positioning, so that the LEDs are visible.
If the cable diameters of the in-/outputs exceed 1.5 mm
FFor cables with diameters of 1.5 ... 2.5 mm
For larger diameters, a corresponding terminal must be provided by the customer. The terminal can
be placed in the housing.

Procedure:
1. Take the 2 labels with the serial number off the housing bottom. Attach one label
onto or into the radio gateway, so that the radio gateway can still be identified
when it has been fixed. The other label is intended for the building plan.
2. Break out the cable entries depending on the type of feed line mounting:
Flush-mounted feed lines: Break out the openings in the surface area of the
–
housing bottom.
Surface-mounted feed lines: Break out the openings on the front side of the
–
housing bottom.
3. Guide the cable through the housing bottom and mount the housing bottom with
2 screws (max. Ø 4.3 mm) onto an even surface.
4. Prepare the wires of the detector line so that they can later be connected to the
spring clip 'LINE'.
5. Connect the positive and negative poles of the detector line each with a
microterminal or with a connection terminal (to be ordered separately). To be
tested, the detector line must not be interrupted.
6. If the detector line cables are shielded, connect the shielding of the two detector
line cables (incoming and outgoing) to the spring clips 'SHIELD'. To insert the
wire, release the spring clip with a screwdriver. Connect only one wire to each
spring clip! The shielding must not touch any extrinsic earthing potentials or
metal parts in the device.

, auxiliary terminals must be used.
