Connecting Power
To connect a power supply to the battery charger:
l Connect the 24 VDC power supply to the 24 V Jack connector.
l If you do not have a 24 VDC power supply with a Jack connector, first loosen
the terminal locking screws, connect two wires to the 24V terminal block, and
then secure the wires using the locking screws.
Note: Make sure that the device is oriented vertically. Do not mount the
device at an angle.
Charging Batteries
Multi-Battery Charger has two charging modes:
l Fast charging
l Standard charging
To initiate either of the charging modes, insert DM8700 battery into an empty
charging slot with the connector plates of the battery pointing down.

Fast Charging
Fast charging is only available in two slots, in the far right and left slots.
Note: If batteries are also inserted into the standard charging slots,
fast charging is disabled, and only standard charging is possible, even in the
fast charging slots.
- Place the batteries into either or both of the two fast charging slots. Up to two batteries can use fast charging at a time.
- Press down the battery until you hear the battery snap in place.
- If the charger is connected to a power source and the battery needs charging, the fast charging sequence starts automatically, indicated by red battery charging indicators. Fully charged batteries are indicated by green attery charger indicators.
- To remove a battery from the charger, simply pull out the battery from the charging slot.
Standard Charging
All slots are capable of standard charging, but the second and the third slots
are only capable of standard charging.
- Insert one or more batteries into the empty charging slots with the connector plates of the batteries pointing down.
- Press down the battery until you hear the battery snap in place.
- If the charger is connected to a power source and the batteries need charging, the charging sequence starts automatically, indicated by orange battery charging indicators. Fully charged batteries are indicated by green battery charger indicators.
- To remove a battery from the charger, simply pull out the battery from the charging slot.
Examples for standard charging:
Mounting
When mounting the battery charger, leave at least 150 mm (5.9 inches) above
the unit to allow batteries to be inserted and removed.
Use the mounting keyholes or the M3 threaded inserts to securely mount the
MultiBattery Charger on a wall, or other flat, solid surfaces.
Make sure that the wires are not pinched or bent and the charger is not
mounted in a corner.
Note: Make sure that the device is oriented vertically. Do not mount the
device at an angle.
