Pay attention to the instructions for the connection of the power supply
The connections are described in appendix "A Connection Diagrams".
Danger! Absolutely pay attention:
Mounting, installation, commissioning and repairs of electrical devices must only be
carried out by a licensed electrician. While the national installation regulations must
be adhered.
For the mains power input a 3 wire mains power cable (2P + PE) with a cross
section of at least 0.75 mm
2
has to be used.
For each power supply connection (
Mains ) / ( DC In ) / ( Bat + )
two fuses of 10A
(13A) slow has to be provided (in both lines).
The used fuses for the DC- and battery supply have to be approved for DC.
Each power supply connection (
Mains ) / ( DC In ) / ( Bat + )
needs to be realized
with an all-pole disconnection device, which is installed near to the device
mentioned in this manual, which is clearly labeled and good accessible.
Before working on a device or on the electrical installations the corresponding
circuits have to be switched off and secured against uncontrolled power on.
In case more than one supply voltage is used, including battery power supply, all of
them have to be disconnected before starting any maintenance work.
