4. OFF-BOARD (SHELF) VERSUS ON-BOARD (BUILT-IN) CHARGERS
This section describes how the charger operates when the charger type is set to Off-board or On-board.
Based on your application, this setting can be changed via the ChargerConnect app
under “System Profile”
(see Section 8).
The charger was factory-c onfigured wit h the active battery profile that was requested as part of the original
order from Lester Electrical. The charger was also factory-configured for mounting on -board a battery-
powered vehicle/machine or for off-board use in a shelf or portable application per the original order from
Lester Electrical. B efore (1) using the charger fo r the first time or (2) using the charger with a battery pack of
a different type or capacity, use the ChargerConnect app to verify that the proper active battery profile is
selected and that the system settings match your application (see Section 8).
4.1 Off-Board Chargers
Off-board chargers are designed to be used in shelf or portable applications. If t he A C input plug is
connected to A C power, a new charge cycle automatically starts when the DC output is connected t o a
battery pack of the proper voltage. Disconnecting and reconnecting AC power while the DC output remains
connected to a battery pack WILL NOT automatically start a new charge cycle. Disconnecting the DC output
from the battery pack IS REQUIRE D to automatically start a new charge cy cle.
4.2 On-Board Chargers
On-board chargers are designed to be mounted on electric vehicles/equipment. If the DC output is connected
to a battery pack of the proper voltage, a charge cycle automatically starts when the A C input plug is
connected to AC power (unless a safety period of time has not passed since the successful completion of the
previous charge cycle). Disconnecting the DC output from the battery pack IS NOT REQUIRE D to
automatically start a new charge cycle.
5. AC INPUT
CAUTION: TO REDUCE THE RIS K OF ELECTRIC SHOCK OR FI RE, DISCONNECT AC POWER
FROM THE CHARGER BEFORE INSTALLING OR REMOVI NG UNIT.
The charger has an A C input rating of 100 -240 volts, 50-60 hertz, single-
phase. The charger has an AC operating range of 85-265 volts, 45-65
hertz. Below 108 volts, the charger may reduc e output power.
The c harger is equipped with an IEC 60320 C16 inlet for t he A C input
power as shown. This allows the A C power cordset to be selected with a
proper plug compatible with loc al electrical codes. The A C power cordset
must be a minimum of 14 AWG (2.0 mm
2
) for proper operation. An AC
cord clamp is also included to retain the A C power cordset IEC 60320 C15 connector. Loos en the screw on
the side of the clamp as shown before inserting the C15 connector. Fully insert the connector into the charger
inlet and then tighten the AC cord clamp screw to secure the AC power cordset to the charger.
The charger must be grounded to reduce the risk of electric shock and is equipped with an IEC 60320 C16
inlet having an equipment-grounding conductor and a grounding socket. The installed AC power cordset
must be plugged into an outlet that is properly installed and grounded in accordance with all applic able
electrical codes and ordinances.
If this charger includes the UL Listed symbol on its ratings label, it is provided with a cord set for connection to
outlets operating at nominal 120 volts (or 240 volts as appropriate). If the input plug does not fit the power
outlet, contact Lester Electrical for the proper cord set terminating in an attachment plug of the proper
configuration for the power outlet.
