Invacare G40 - Voltage Supply Checks and Repairs; Check of Batteries, Battery Box, and Battery Voltage

29
Measure voltage
• Bring seat system in service position and arrest.
• Pull double tension belts (3) upwards and remove sidewards from battery box cover (2).
• Remove battery box cover (2) upwards out of wheelchair.
• Check single and total voltage of batteries with a multimeter (range 50V / 25V DC).
Disassembly
• Release screwings and remove connections (4), battery pole clips (6), cable form (7) and battery pole
plate (5).
• Pull up grips and remove batteries (8) carefully upwards out of wheelchair.
• Release cross slotted screws on left and right side at bottom of battery box (1) and take out box.
• Release screws and nuts M5 and remove double tension belts.
Assembly
• Assembly is carried out in reverse order.
CAUTION:
• Be careful with tools..
Do not bridge battery poles.
> Danger of short circuit <
• Note the high weight of batteries.
>Danger of crushing <

NOTE:
• Secure that both batteries are loaded.
If total voltage lies under 24 V, load batteries completely (see chapter 10.2).
• Sinks batteryvoltage during operation under 24 V, the voltage supply to the motor is interrup
ted and remote display flashes.
• The voltage of each battery should not sink under 11.5 V.
• A fall of voltage can be checked in driving mode with switched on lighting system and
applied hand brake.
• Voltage of a battery under 11.5 V?
• Voltage falls heavily down under load
(driving operation, handbrake applied,
switched on lighting system) ?
• Battery contacts corrosioned or damaged?
• Check all cables and plug connections.
• Battery box or battery box coverdamaged?
• Double tension belt damaged?
• Grip with carrying strap damaged?
> Load batteries (see chapter 10.2).
> Load batteries (see chapter 10.2) or replace.
> Clean or replace contacts.
> Replace if necessary.
> Replace if necessary.
> Replace double tension belt.
> Replace if necessary.
