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.
