3.3 Electrical connection
Connect the internal device to the mains according to the instructions described in this chapter.
CAUTION
Connecting the device to the electrical network has to be performed in accordance with the
standards for connecting devices to the electrical network. The device has to be connected
to the electrical network via the power supply cut-off which is installed into the electrical
installation under the regulations in force. The power supply cut-off has to separate all
contacts under the regulations of the overvoltage category III - minimal spacing between
contacts is 3 mm.
DANGER
The final electrical connection, before commissioning can only be performed by the person
authorised by the manufacturer to ensure the correct and efficient operation of the device.
IT IS STRICTLY PROHIBITED FOR UNAUTHORISED PERSONS TO TAMPER WITH
THE ELECTRICAL CONNECTION OF THE DEVICE.
DANGER
The device must be connected to the mains, which has a built-in RCD
residual-current device,
switch type A.
CAUTION
The device must be connected to the mains with a cable with an appropriate
diameter
. The
electrician defines the diameter of the cable according to the
installation method, distance
of the device from the main electrical cabinet and the
power
of the device.
CAUTION
The supply and communication cables have to be laid into the device and electrical cabinet
through separate envisioned ducts and overflows which are installed before the cable clamp.
This way we ensure the cable is relieved and the electrical cabinet is protected from water
penetration.
CAUTION
The communication cable must not be laid together with energy cables (in accordance with
good engineering practise and regulations).
