ATTENTION!

High voltage!

Make sure the regulator is disconnected from 

the mains before working on the power 

supply (cable connections, device 

installation, etc.)!

All connection works must only be carried 

out by qualified electricians.

Before activating the controller, measure the 

motor resetting efficiency and inspect wire 

insulation.
