ELECTRIC EQUIPMENT
The electric equipment works in single-wire system of a direct
current with rated voltage 24V. The negative pole of a current source is
connected to the ground.
GENERATORS
On the power unit, depending on model and the complete sets
can be installed the generators of several models (see section “Com-
plete set”).
