Using the DC kit
Driving mode: power supply from the 24 V battery with motor
switched off
• CA1000, CA2500, B2200, B1600 Plus, FJ1100, FJ1700, FJ2200,
FL1600, FL2200, FW3000
If the inverter switches off due to low voltage in the supply battery (21 V), no
voltage will be supplied to the socket and the roof air conditioner switches off.
The inverter is in standby mode.
As soon as the power from the supply battery reaches the inverter's activation
point, the socket is supplied with voltage again.
You have to switch on the roof air conditioner again manually, as the control
electronics need to be reactivated after a lack of voltage.
• B1600, HB2500
If the inverter switches off due to low voltage in the supply battery (21 V), no
voltage will be supplied to the socket and the air conditioner switches off. The
inverter is in standby mode.
As soon as the power from the supply battery reaches the inverter's activation
point, the socket is supplied with voltage again.
The air conditioner starts automatically.
Driving mode: power supply from the 24 V battery with motor
switched on
In driving mode, the starter and supply battery are electrically connected when the
light system is active. This means the supply battery can be charged from the light
system.
Starter batteries may not be discharged as much as supply batteries. To preserve the
starter battery, the charging current distributor separates the starter battery from the
supply battery, if the charging voltage in the starter battery drops below 21 V. This
also ensures that the starter battery is charged before the supply battery.
• CA1000, CA2500
If the charging voltage regulator cuts the connection to the supply battery due
to low voltage, it switches off the compressor in the roof air conditioner at the
same time. The inverter remains active and has voltage in its socket.
As soon as the voltage in supply battery has reached the switch-on point in the
charging current distributor, the compressor in the roof air conditioner switches
on again.
If the voltage in the supply battery drops further and goes below the 21 V switch-
off point for the inverter, the inverter switches off (chapter "Driving mode: power
supply from the 24 V battery with motor switched off" on page 22).
