battery chargers EHP-50G accessories are powered by either internal rechargeable
batteries or directly from other devices to which they are connected.
The AC/DC battery charger (650.000.036) can be used with a power
frequency at either 50 Hz or 60 Hz with a supply voltage between 100 and
240 AC Volt. International AC plug adapters are provided according to the
various national standards.

replaced by a different one.
To have the greatest autonomy, a full recharging cycle should be carried
out before using the Accessories.
ALWAYS connect the battery charger to the mains BEFORE
connecting to the charge input of the accessories.
The battery charger has an internal protective circuit that will break
the output if any load is detected while connecting to the mains.
