4.2 Wiring
4.2.1 Wire Routing
All wiring must be installed in accordance with NFPA70 [NEC760] and all local code
requirements.
Power Limited wiring requires that power limited and nonpower limited wiring remain physically
separated. All power limited circuits must remain at least one quarter inch (¼") away from any
nonpower limited circuit wiring.
CAUTION - A lead-acid or gel cell battery can supply large amounts of current. Although
the RMBE has limiters on each battery, care should still be taken when wiring the RMBE to
prevent personal or property damage. Always remove the terminal st rips when wiring an
RMBE and ensure proper wiring before reconnection of the terminal strips.
