Altronix AL1002ULADA Installation Manual page 7

NEC Power-Limited Wiring Requirements for AL1002ULADA Models:
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 con-
duit 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.
Note: Refer to wire handling drawing below for the proper way
to install the CM or FPL jacketed wire, (Fig, 2a).
