Nec Power-Limited Wiring Requirements - Altronix Maximal Fit Series Installation Manual

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 differ-
ent 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 UL Listed
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 (Fig. 3b).

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

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.
A UL listed external battery enclosure must be
used if using the 40AH or 65AH batteries.
