Usage

Safety information

WARNING!

• Circuit breaker or fuse protection in the AC power outlet to which the charger is to be plugged should be rated at 5 Amps per charger. A delay-action fuse is recommended.
• Do not overload electrical outlets.
• Avoid use of an extension cord. Use of an improper extension cord could result in the risk of fire and electric shock. If an extension cord is necessary, ensure a 5 Amp current rating or greater and that it is in a good condition and as short as possible. If an extension cord is used, it should be used in accordance with the extension cord manufacturers’ instructions.
• Use compatible extension cord connectors on the battery charger connector.
• Situate all cords in such positions as to eliminate the likelihood of being stepped on, tripped over or otherwise subjected to damage or stress.
• Do not operate the charger if the power cord is damaged. Contact a provider immediately.
• Do not operate the charger if it has suffered a sharp blow or is damaged in any other manner. Contact a provider immediately.
• Do not charge individual 12 volt batteries.

WARNING!

• Use only with a 220 – 240 V AC / 50 – 60 Hz mains supply.

WARNING!

• Keep charger protected from rain and moisture. In the event of water or other fluid entering the unit, switch unit off at the mains supply and unplug from the power supply and wheelchair immediately. Contact your provider.

WARNING!

• Do not attempt to open the case. There is a risk of electric shock, even if the unit is unplugged. There are no fuses or user-serviceable parts inside.
• Do not insert objects through the cooling slots.

WARNING!
Explosive gases may be vented from the batteries during the normal operation of battery chargers.

• Do not smoke or expose naked flame in the vicinity of the charger.
• Only use charger in a ventilated area.

Using The Battery Charger

CAUTION!
Risk of injury from hot surfaces The XLR plug can become very hot during charging.

• Do not touch XLR plug during charging.
• Do not remove XLR plug until mobility device is fully charged.
• Remove mains lead from power socket and wait until XLR plug cooled down.

1. Switch OFF mobility device.
2. Connect XLR plug B to mobility device to be charged.
3. Connect the mains lead A to a suitable power socket. Battery level indicator LEDs D/E/F flash once. Power LED C illuminates green. This indicates that battery is correctly connected and is charging.
4. When charging is complete first disconnect mains lead  from power socket and then XLR plug from mobility device.

LED Indication

NOTICE!

• Batteries repeatedly charged to and used at partly charged level will suffer a greatly reduced battery life.
• While connected to a charger the state of charge should be read solely from the battery charger indicators and not from the mobility device.

“Battery Discharged” LED D illuminates yellow when the battery is discharged and charging is in progress. A battery with a low charge state should recharge in approximately 12 hours. Smaller or partly charged batteries will take proportionally less time to become fully charged. “Battery Partly Charged” LED E illuminates yellow in addition when the battery is partly charged (> 50 %). A mobility device with batteries at this charge level or below must be used in emergency situations only. “Battery Fully Charged” LED F illuminates green in addition (all LEDs are on) when the battery is fully charged. When LEDs D and E are flashing an error has occurred:

• Check for correct connection
• Contact your local provider
