POWER SOURCES
The balancer may be powered in three different ways.
1. Power Converter/Charger.
The normal power method is to use the power converter
supplied with the equipment. This converter furnishes
8.5 VAC ,with sufficient power to operate the equipment
and charge the battery.
2. Battery.
The balancer is equipped with an 8 volt, 8.5 Ampere-
Hour lead-acid, maintenance free, gel-cell battery (2
each Technacell 4 volt, 8.5 Amp-hour, Model EP485
or equivalent) to allow operation when normal power
is not available. The normal power converter should
be used to keep the battery charged whenever the
balancer is not in operation. There is no need to unplug
the converter since the battery can not be overcharged.
It requires a minimum of 12 hours to fully charge the
battery.
In cases where the battery is allowed to become fully
discharged, the balancer will still operate normally from
the power converter or an external 12 volt battery.
If the balancer is not used for approximately 10 minutes,
the computer puts the equipment into a standby mode.
This reduces the power consumption to less than one
watt, except for the power required to charge the
battery. If the balancer is being operated from the
battery, the standby mode will continue to discharge
the battery but at a very reduced rate.
Battery life can be expected to be approximately 5
years. Life can be extended by maintaining a full charge
and avoiding excessive vibration and temperature
variations. If the battery is replaced, care must be taken
to reconnect with the correct polarity. If the polarity is
reversed the 3 Amp fuse (type 3AG/AGC or equivalent)
located in the battery compartment will blow. Should it
be necessary to replace the fuse,
DO NOT
use a slow-
blow type or any other rated battery.
Note: Black lead connects to the (-) terminal; Red
lead with fuse connects to the (+) terminal.
3. 12v Battery Operation.
The balancer may be powered by any 12 volt battery.
Connection is made to the same input connector as
the normal power converter. In this case either polarity
may be used, as the computer can operate from either
a +12 volt or -12 volt DC source.
