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!
