Wiring connection

WARNING
A main switch or other means for disconnection, having a
contact separation in all poles, MUST be incorporated in
the fixed wiring in accordance with the applicable
legislation.
You can use a single switch to supply power to units on the same
system. However, branch switches and branch circuit breakers
MUST be selected carefully.
Fit the power supply wiring of each unit with a switch and fuse as
shown in the drawing below.
