ATTENTION: SW1 only disconnects L1, not both sides of the AC
powerline.
See "RTP Cable wire positions, colors, and internal schematic" on page 1 for
more information.
4. Connect field wiring.
CAUTION: S-L1 terminals in the wiring figure below are live when switch
SW1 is on (1).
AC Outputs are individually fused in the module, but adding a fuse here
protects the wiring.
