NEC Power-Limited Wiring Requirements:
Power-limited and non power-limited circuit wiring must remain separated in the cabinet. All power-limited circuit
wiring must remain at least 0.25” away from any non power-limited circuit wiring. Furthermore, all power-limited
circuit wiring and non power-limited circuit wiring must enter and exit the cabinet through different conduits. One
such example of this is shown below. Your specific application may require different conduit
knockouts to be used. Any conduit knockouts may be used. For power-limited
applications use of conduit is optional. All field wiring connections must be made
employing suitable gauge CM or FPL jacketed wire (or equivalent substitute).
Optional battery enclosure must be mounted adjacent to the power supply via Class 1
wiring methods. For Canadian installations use shielded wiring for all connections.
Note: Refer to wire handling drawing below for the proper way to install the
CM or FPL jacketed wire

Applications
Note:
12V batteries
are required for
ULC-S319
installations.
CAUTION: When power supply board is set for 12VDC use
only one (1) 12VDC stand-by battery.
Connect red battery lead to the terminal marked [+ BAT] and to
the [positive (+)] terminal of the battery.
Connect black battery lead to terminal marked [BAT –] and to
the [negative (–)] terminal of the battery.
Keep power-limited wiring separate from non power-limited.
Use minimum 0.25" spacing.
12AH Rechargeable batteries are the largest batteries that
can fit in this enclosure.
An external battery enclosure must be
used if using the 40AH or 65AH batteries.
