Supply conditions
Range Description
Fuses l Utilisation category: only gG/gL or gRL
Cables Laying systems B2 and C: Use of PVC−insulated copper cables, conductor
temperature < 70 °C, ambient temperature < 40 °C, no bundling of the cables or
cores, three loaded cores. The data are recommendations. Other
dimensionings/laying systems are possible (e.g. in accordance with VDE 0298−4).
RCCB l Controllers can cause a DC current in the PE conductor. If a residual current
device (RCD) or a fault current monitoring unit (RCM) is used for protection in
the case of direct or indirect contact, only one RCD/RCM of the following type
can be used on the current supply side:
– Type B (universal−current sensitive) for connection to a three−phase system
– Type A (pulse−current sensitive) or type B (universal−current sensitive) for
connection to a 1−phase system
Alternatively another protective measure can be used, like for instance
isolation from the environment by means of double or reinforced insulation,
or isolation from the supply system by using a transformer.
l Earth−leakage circuit breakers must only be installed between mains supply
and controller.
Observe all national and regional regulations!
