4.6 General Wiring Recommendations
Route and connect ground, power, and alarm cables to the panel connectors according to local
practice and the specified procedures. The connections to the fuse panel are shown in Figure 18.
After routing the cables, tie them to the cable management bar (optional accessory). Replace the
protective cover on the fuse panel after all the wiring connections are made and all tests are
completed.

Connectors and Screw-Down Barrier Terminal Strip Output Connectors Shown)
Caution: Connect both buses of the fuse panel to only –24 Vdc or –48 Vdc.
Caution: Connect only the input voltage wire [the wire labeled BATTERY or BATT, or labeled
with the negative (–) voltage polarity and/or the voltage value] to the connector on the fuse
panel labeled BATT (battery). Connect only the input return wire [the wire labeled RTN,
RETURN, or BATTERY GROUND, or labeled with the positive (+) voltage polarity] to the
connector on the fuse panel labeled RTN (return). If the wires are reversed, voltage could be
present on the fuse panel chassis and current could flow through the unprotected return wiring
in the fuse panel. This condition can cause damage to equipment in the frame in which the fuse
panel is installed and to equipment in adjacent frames!
