Connection

Read the Safety chapter and, in particular, the section on Installation and
Commissioning (see chapter 1.7) before connecting the device. Do not remove
the identification plate.
Warning!
Risk of short circuit
Injuries and damage to the device are possible when working with live parts.
Before working on the device, always disconnect the supply voltage.
■
Connect the device to the supply voltage only after completion of the work.
■
Take care not to reverse the polarity when connecting the sensor cable. The loop
resistance of the extension cable should not exceed
20 Ω for the sensor KVF-104-PF, SLU-103-**.
■
10 Ω for the sensor NVF-104/34-PF.
■
For extending the sensor cable, use cable connector LAL-SK2.
Note!
Avoid installing sensor cables parallel to other cables that may transmit interfering
signals, which impair the sensor signal and thus the alarm function. Use
unshielded 2-wire cable for each sensor.
To ensure perfect operation of the warning device, do not exceed:
the max. cable length of 190 m with a cross-section of 0.75 mm
■
the max. cable length of 250 m with a cross-section of 1 mm
■
The product is a Class II device (with reinforced insulation). Connect the power
supply as follows:
Terminal 7: phase (F/L2)
■
Terminal 6: zero (N/L1)
■
Terminal 5: ground (loop terminal)
■
Note!
Additional relays can be connected via terminals 1 to 3 and 10 to 12. They can be
used, for example, for an external alarm or the connection to a central monitoring
system.
