3.5.2 Wiring the External Batteries
You can use external batteries as the main source of power for the
ROC800 with the 12 volts dc Power Input module (PM-12). The
maximum voltage that can be applied to the BAT+ / BAT– terminals is
16 volts dc before damage may occur. The recommended maximum
voltage is 14.5 volts dc (refer to
Table 3-2
concerning LEDs).
It is important that you use good wiring practices when sizing, routing,
and connecting power wiring. All wiring must conform to state, local,
and NEC codes. Use 12 to 22 American Wire Gauge (AWG) wire for
all power wiring.
Batteries should be rechargeable, sealed, gel-cell, lead-acid batteries.
Connect batteries in parallel to achieve the required capacity (refer to
Figure 3-6
). The amount of battery capacity required for a particular
installation depends upon the power requirements of the equipment and
days of reserve (autonomy) desired. Calculate battery requirements
based on power consumption of the ROC800 and all devices powered
by the batteries.
