(although a minimum gauge of 16AWG has been acceptable). This bonding
connection is necessary to prevent internal damage to the power module in the
event of any accidental reversed polarity connections or accidental connections
between the battery positive wiring and the case of the power module.
8. A Remote User Interface (RUI) module must be connected to the power module
using two CAT-5 cables. The COMM1 jacks should be connected together and
the COMM2 jacks should be connected together. If the cables are not connected
or if they are interchanged, the power module will not operate. The RUI may be
either a Tripp Lite RUI or a customer designed RUI that meets Tripp Lite
specifications.
9. The power module includes a low voltage cutoff (LVC) function that will remove
any load on the battery when the battery is depleted. The LVC level is about
10.5V to assure optimum battery cycle life. If any other DC loads are present in
the system, they need to include their own LVC function in order to prevent
damage to the battery due to over discharge.
10. The power module will not turn on unless connected to a battery that has a
voltage greater than 9.6V. If the battery voltage is less than 9.6V, it is assumed
to be defective and the charger is inhibited in order to prevent possible
outgassing of the battery.
11. The power module reports % Battery Capacity through its USB port. This data is
most accurate when a 55AH sealed lead acid absorbed glass mat (AGM) battery
is used. Batteries of other capacities may be used, but the accuracy of the
% Battery Capacity report will be reduced.
12. After connecting a battery to the power module, the power module should be
allowed to charge the battery to full capacity in order to initialize the % Battery
Capacity report and the % Battery Capacity LED’s (on the RUI). This will take at
least 4 hours, even with fresh battery. The % Battery Capacity
report and LED’s
will not be accurate until after the initial charge has been completed. After
initialization, the power module will properly indicate the % Battery Capacity as
the battery is repeatedly discharged and recharged. However, each time the
battery is replaced, the initialization will need to be repeated.
