7. Connection of the input and output power
7.1 Connection of the input power
Please take care, that the cabling at the power network should be realized like following:
7.2 Connection of the output power
To compensate for voltage drops over the cable length, it is possible to adjust the output voltage with the
integrated potentiometer.
Please note:
To avoid damages at the connected device, please adjust the output voltage to the lowest
level.
To adjust the potentiometer, use a slot screwdriver and turn it to the left until it stops (12 VDC).
Now connect the cable with the power connection terminal and measure the incoming voltage with a
multimeter. If the incoming voltage is too low, you can increase the voltage with the potentiometer.
7.3 Connection of battery backup
The battery backup terminal can be used with gel batteries. The BATT LED is glowing when the system is
supplied by the battery.
To ensure a battery backup with batteries and also to load the battery backup, a higher output current is
needed.
Please note:
To ensure a battery backup, two 12 V batteries must be connected to the terminal
(2 x BT2012).
Warning:
The cabling to the power network should only be done by qualified personnel. The device
works with an input voltage of 230 VAC!
