4.2 Wiring
4.2.1 Wire Routing
Wiring must be installed in accordance with NFPA70, NFPA72, and all local code requirements.
Power Limited wiring requires that power limited and non-power limited wiring remain physically
separated. Any power limited circuit entering the enclosure must remain at least one quarter
inch (¼”) away from any non-power limited circuit wiring. Any power limited circuit wiring
must enter and exit the enclosure through different knockouts than non-power limited circuit
wiring.
Wiring within the enclosure should be routed around the perimeter of the cabinet. It should not
be routed across the circuit boards.
4.2.2 AC Input
Connection should be made via wire nut. AC mains wiring should be no smaller than 14 AWG.
See Section 3.3 for details.
4.2.3 ABC Connector
See section 3.4
4.2.4 Output Wiring
Locate the output terminals to be used (DC1, DC2, or DC3). These terminals are non-
removable and accept wire sizes between #12 and #22 AWG. Polarity is indicated on the PCB.
4.2.5 Battery Wiring
Locate the battery terminals. These terminals are non-removable and accept wire sizes
between #12 and #22 AWG. Polarity is indicated on the PCB.
For 12VDC connect one battery to the terminals
For 24VDC connect two batteries in series to the terminals
Note: Connecting batteries in parallel does not allow the BNx000 to supervise the entire battery
set for presence.
CAUTION: A lead-acid battery has the capability of producing extremely high
current. Personal or property damage can occur if the batteries are shorted or
improperly connected.
