Note: Refer to Table 3-2 concerning LEDs.

3.5.2Wiring the External Batteries

You can use external batteries as the main source of power for the ROC827 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 American Wire Gauge (AWG) or smaller 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 ROC827 and all devices powered by the batteries.
