Connection
➭
Remove terminal rail cover.
➭
Connect
• sensor lines,
• MFA output,
• pump or change-over valve,
• voltage supply
according to the hydraulic variation installed
(Ch. 4).
➭
Secure all connected cables with the traction reliefs
supplied.
➭
Apply voltage, if fault message appears check sensor
connection, if necessary adjust hydraulic variation.
➭
Refit terminal rail cover once the relevant cable cut-outs
have been opened, use screws (traction relief)
supplied.
Improper installation or repair attempts can
cause life-threatening conditions through
electric shock. The installation must only be
carried out by an electrician with the relevant
qualifications.
The unit and accessories must not be opened.
Repairs must only be carried out by the
manufacturer.
