Only an authorised electrician may perform the electrical installation and mainte-
nance of motorized switch-disconnectors. Do not attempt any installation or main-
tenance actions when a motorized switch-disconnector is connected to the electri-
cal mains. Before starting work, make sure that the switch-disconnector is
de-energised.

When relay outputs are used with inductive loads (such as relays, contactors and
motors), they must be protected from voltage spikes using varistors, RC-protectors
(AC current) or DC current diodes (DC current).
The control voltage (output C = 24Vdc) on the control terminal is non-isolated, see
box 2 in Figure 4.1.
Do not couple power for the control terminal. See the correct terminal for the power
supply in Figure 4.1.
