ELECTRICAL CONNECTIONS
When connecting the controller, both VDE, National Electric
Code NEC (or equivalent) and any local regulations con-
cerning grounding and zero voltage must be observed.
Electrical work should be carried out by a qualified electrician.
Under no circumstances should spare controller terminals be
used as wiring support points. Doing so could damage the
modules.
The electrical connections must be made at the terminal
blocks. Maximum torque for fastening the wiring terminal
screws is 0.5 Nm (4.5 lb-in). The corresponding connection
diagrams are on the individual modules.
WARNING
Switch power OFF before making connections to or
removing connections from terminals to avoid
electrical shock or equipment damage.
