WARNING
In a permanently routed installation, there must be an in-series
disconnecting and isolating device to separate the WAREMA climatronic
from the supply voltage (switch according to EN 60335-1, Section 25.2,
e.g. circuit breaker).
DANGER
The components must be disconnected from the mains voltage before the
enclosure is opened.
When establishing the supply line connection, apply EN 60335-1 (line cross-
section, line type, additional locks to prevent loosening, strain relief, wire
ferrules for wire conductors, circuit breakers).
The operator or installer is responsible for compliance with the public utility
provider regulations and the VDE regulations according to VDE 0022.
The wiring specified in the cable diagrams is for minimum cross sections
in copper, taking no account of the length and the resulting voltage drops.
The relevant VDE regulations must be followed when routing lines outdoors.
Furthermore, the lines must be suitable for outdoor use. The distance to high-
voltage power lines must be at least 20 cm; parallel routing to lines carrying
mains voltage must be avoided. The insulation voltage between shielding
and wires must be > 2.5 kV. The lines should be routed in one piece.
NOTE Common low-voltage cables (e.g. JY(St)Y) are normally used for switch, sen-
sor and network lines. This is usually sufficient regarding EMC interferences,
e.g. in residential rooms at line lengths up to 50 m. By contrast, optimal pro-
tection against EMC interference is provided by high-quality lines with braid-
ed shields (no foil shields) and tightly twisted cable pairs. The longer the line,
the greater the susceptibility toward interference. For this reason, only install
high-quality cables.
WARNING
The electrical installation must be performed by a certified electrician in
accordance with the electrical installation regulations published by the
Association of German Electrical Engineers (VDE 0100) or the standards
and regulations of the country in which the device is being installed.
