Battery Compatibility
The installed power supply (170W or 300W) determines the charging current pro-
vided by the PAD-
5’s charger and the compatible battery sizes as shown in the fol-
lowing table.

The PAD-5 uses the power supply selected in the panel configuration tool (e.g.,
Zeus) to set the charging current. This selection also limits the available battery siz-
es in the configuration tool to those shown in the table. Additionally, the PAD-5 con-
firms that the power supply selected and the installed power supply agree. If they
do not agree, a trouble will be posted on the control panel.
Never select the 300W power supply and then connect 18Ah or smaller batter-
ies to the PAD-5. When recharging is required, the 6A charging current can
cause overheating and premature failure of the battery set.
Terminal X100 must always have a power supply connected.
Do not connect AC or batteries until all jumpers and boards are configured and
connected in the system. Once everything is installed and connected, first AC, then
the batteries must be connected.
To power down the system, first disconnect the batteries and then the AC.
