Units in sizes 1 and 2 are connected with factory installed
electrical plug, otherwise permanently connected to
single phase 230V, 50Hz, 10A.
For size 3 permanent connection applies, 2 x 230 V + N,
50 Hz, 2 x 10 A.
2.2 Safety
Lockable isolator switch is located on the control enclo-
sure.
2.3 Display
The display is connected to the unit via contact on the
