Do not connect the ground to the neutral (N) leg at the terminal strip (if so equipped).
If a DELTA supply system is used, the high leg should be connected to L3, since control voltage is
derived from L1 and L2.
Note:
Ensure that all power connections are tight. Loose connections will
cause burned wires and contactors on electrically heated machines.
Check the electrical connections at the incoming power terminal block,
contactors, and heating elements at installation, after the first week of
operation, and quarterly thereafter. Failure of switchgear due to negli-
gence in this area is not covered under any warranty!
