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