DESCRIPTION OF THE BATTERY CONDITION INDICATORS
The battery condition indicators give a relative indication of the state of charge of the battery pack. A fully charged battery pack will measure above 37.6 volts
with no load applied (2.09 volts per cell). The AquaRide
™ SE / BRX 700 is equipped with a low voltage cutout feature that will turn the scrub system off when
the batteries are discharged to their minimum level. There are two different cutout levels to accommodate different battery types. See the service manual for
details. The voltage levels for the various indications are as follows (the voltages shown represent the voltage under load):
INDICATOR VOLTAGE LEVELS FOR STANDARD CUTOUT LEVEL (AS SHIPPED)
Green indicator = full charge down to 34.00 volts
Green & Yellow indicator 33.99 volts down to 33.00 volts
Yellow indicator = 32.99 volts down to 32.00 volts
Yellow & Red indicator = 31.99 volts down to 31.50 volts
Red indicator = 31.49 volts down to 31.00 volts
Flashing Red indicator = less than 31.00 volts – scrub system will shut down.
INDICATOR VOLTAGE LEVELS FOR ALTERNATE CUTOUT LEVEL
Green indicator = full charge down to 34.50 volts
Green & Yellow indicator 34.49 volts down to 34.00 volts
Yellow indicator = 33.99 volts down to 33.50 volts
Yellow & Red indicator = 33.49 volts down to 33.00 volts
Red indicator = 32.99 volts down to 32.5 volts
Flashing Red indicator = less than 32.5 volts – scrub system will shut down.
NOTE: Refer to service manual for selection of alternate cutout level.
NOTE: Once the low voltage cutout level has been reached (fl ashing red indicator) the batteries must be FULLY recharged (37.6 volts) to reset the battery
condition indicator. The scrub system will not function until the indicator has been reset.
INSTALL THE BATTERIES
WARNING !
Use extreme caution when working with batteries. Sulfuric acid in batteries can cause severe injury if allowed to contact the skin
or eyes. Explosive hydrogen gas is vented from inside the batteries through openings in the battery caps. This gas can be ignited
by any electrical arc, spark or fl ame.

CAUTION !
Electrical components in this machine can be severely damaged if the batteries are not installed and connected properly.
Batteries should be installed by Nilfi sk-Advance or by a qualifi ed electrician.
1 Turn the Key Switch (J) off (O) and remove the key. Then swing open the Battery Compartment Cover (16).
2 Using (2) people and an appropriate lifting strap, carefully lift the batteries into the compartment tray exactly as shown. Use decal 56015168 battery
cable layout.
3 See Figure 1. Install battery cables as shown and tighten the nuts on the battery terminals.
4 Install the battery boots and secure tightly to the battery cables with the supplied tie straps.
5 Connect the battery pack connector to the machine connector (22) and close the battery compartment cover.
