7.5.2 Cable Management
Using cable restraints (e.g., pogo sticks) or other types of cable man-
agement will help prevent damage to the cables and connectors; these
are outside of the warranty. Excess cable should always be restrained
out of the path of lift equipment. Cables and connectors should never
be allowed to lay on the floor.
For dual cable chargers using pogo type restraint, it is best to have
one cable restraint for each set of cables. Bundling both cables onto a
single pogo will overload the spring and cause failure.
7.5.3 Charger Communication Setup
CAN enabled chargers require the communication speeds (also known
as "baud rate") to be the same on both charger and battery. When
setting up the charger, ensure the baud rate setting is equal to the
battery setting. Refer to the specific charger manufacturer's instruc-
tions to determine and change this setting if necessary. The battery
baud rate is set from the factory to communicate properly with the
UIM or CAN integrated truck. For reference, if the battery uses a UIM
the baud rate will be 125 kbps, so the charger must be also set to 125
kbps. On many CAN integrated trucks the baud rate is set to 250 kbps
so the charger will need to be set to a baud rate of 250 kbps. For the
required baud rate of the battery, contact the local Deka representative
or Navitas Product Support.
7.5.4 Anderson Euro Key
If you are using a charger equipped with one or more Anderson Euro
type connectors, it is strongly recommended a voltage key be installed
into all charger connectors, see photo below. The voltage setting is
not important, and a key is not needed in the battery side connector.
The installation of the voltage key will help prevent operators from
incorrectly forcing the euro connectors upside and causing a reverse
polarity connection.
Reverse polarity connections can cause arcing and potentially,
expensive damage to the battery and/or the charger.
Note: Reverse polarity connection damage is not warrantable.

8: OPERATION
The sections below discuss how to power the Deka Ready Power bat-
tery on/off, detect if there was a fault and how to connect and charge
the battery with a Deka Ready Power approved charger. Deka Ready
Power Lithium batteries are not to be used in marine or uncovered
outdoor locations.
8.1 Powering the Ready Power Battery On/Off
Deka Ready Power Lithium batteries have internal contactors that
allow or prevent the flow of electricity to the terminal posts and the
forklift truck. These contactors allow the battery to be "turned on" for
operation and charging or "turned off" for storage, maintenance, and
shipping. How the battery is powered on and off depends on the ac-
cessories equipped with the battery. The following sections give more
detail on each of these accessories and how they control the battery.
8.1.1 User Interface
Module (UIM)
Anderson Euro
The UIM is an accessory with
an LCD screen, menu control
buttons and a power button. The
operator may navigate through
the different pages on the UIM
by using the arrow keys (< >)
located below the screen. See
photo to the right.
Once the UIM is connected to the
battery via the communication
cable, press and release the silver
ON/OFF Power button to turn the
battery and UIM on. Once the
start sequence has finished, the
default user page will be visible.
When on, the UIM's default screen displays the battery State of Charger
(SOC), average internal temperature (°C) and voltage available to the fork-
lift truck. The SOC is shown in both numerical form as a percentage and
in a graph that changes colors from green to yellow to red as the battery
is discharged. Scroll through the other pages, to access the Diagnostics
page to view fault codes. Refer to section 8.4 for more details.
To turn the battery off, press and release the power button to begin
the power down sequence. The UIM will display a countdown message
on the LCD screen. The battery and UIM will turn off when the count
reaches zero.
8.1.2 Battery Discharge Indicator (BDI) 1.0
The BDI 1.0 is a
small accessory used
to power the battery
ON/OFF and display
the State of Charge
(SOC). Refer to the
photo on the right.
To turn the battery
on, press and hold
the BDI ON/OFF power button until all LEDs are illuminated. The bat-
tery will power on and the appropriate LEDs will remain illuminated,
displaying the battery's SOC. It is normal for the bottom LED (red) to
not be lit when the SOC is above 20% and other LEDs are lit. The label
next to the LEDs identifies the range of SOC.
