Note 1: X11 connectors must
be gold. See Appendix C,
Spare Parts for order
number.
Note 2: Either the L1 or N
(L2) terminal can be
connected to a voltage
source up to 240 VAC. The
N terminal can be considered
L2 and is not required to be
grounded. No polarization is
required for L1 and N (L2)
terminals.
