KEYSTONE OM13 - EPI-2 3-WIRES MODULE
INSTALLATION AND MAINTENANCE INSTRUCTIONS
Alternatively, to avoid induced voltage phenomena over floating command line, the following wiring diagram may be used.
Monitor
Switch
(Note 1)
NOTES
1. Supply from 110 to 240 V AC / 1-ph
L2 neutral
When L1 - L2 - L3 cables are long (more than
10 metres) induced voltage phenomena may occur
on floating command line.
To avoid this unwanted effect, realize a cabling
system where unused line (either L1 OPEN or
L3 CLOSE) is pulled to NEUTRAL line. To do this a
switch may be used.
