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!
