Lightning protection
▪
Electrical installations must be protected against overvoltage (compulsory since
14 December 2018) (see DIN VDE 0100-443 (IEC60364-4-44:2007/A1:2015,
modified) and DIN VDE 0100-534 (IEC 60364-5-53:2001/A2:2015, modified).
Whenever modifications are made to existing installations, retrofitting a surge
protective device (SPD) in accordance with VDE is mandatory.
▪
A maximum cable length of 10 metres should not be exceeded between the
surge protective device (usually type 1, internal lightning protection) installed at
the service entrance and the equipment to be protected. For longer cables,
additional surge protective devices (type 2) must be provided in the sub-
distribution board upstream of the equipment to be protected or directly in the
equipment itself.
▪
The associated lightning protection concept must be provided by the operator or
by a suitable provider commissioned by the operator. Surge protective devices
can be offered for the control units on request.
Wiring diagram
The wiring diagrams are located in the control cabinet, which is where they must be
stored.
The product literature of the switchgear and controlgear assembly supplied with the
system includes a list of the electrical components installed. When ordering spare
parts for electrical components, always indicate the number of the wiring diagram.
Terminal assignment
For the terminal assignment refer to the wiring diagram.
5.6.1 Sizing the power cable
Determine the cross-section of the power cable based on the total rated power
required.
5.6.2 On-site protective measures
For protective measures on site observe DIN 14462 for the electrical connection.
5.6.3 Connecting the fire-fighting system
NOTE
If the connection for emergency back-up power supply is connected to the second
terminal, the power supply must be switched between the two power supply
options at the site. The terminals for the power supply options are wired in the
control cabinet. The control cabinet must only be supplied by one of the power
supply options at a time.
ü
Prior to connecting the system to the power supply network, the operator has
made sure that the applicable VDE and country-specific regulations are complied
with.
ü
The power cable has been connected by an approved company.
