Connect AC Input Voltage (P4)
The AC voltage interface supplies both motor (bus) power and logic power.
Using the supplied mating connector, make the following connections:
1.
Connect L1, L2 and L3 (for bus power).
If the main voltage is from a single-phase source, connect line and
neutral to L1 and L2.
If the main voltage is from a three-phase source, connect the phases to
L1, L2 and L3.
2.
Connect the AC input voltage ground wire to the PE terminal, located on the
CDHD front panel. Use an M4 ring or spade terminal.
