Cables
The cables between the battery and the inverter must be sized
according to the table below.
The wiring of the cables is influencing the EMC behavior of the
system, in which the inverter is a component. This is due to the
fact that the cables are receiver and transmitter antennas of
radio frequency electromagnetic interference.
Good EMC properties are obtained in the following way:
Place the cables in a metal rail. The metal offers resistance
against interference currents. The battery cables should be
placed close to each other to reduce looping area. Cables from
different groups should not be twisted but be placed parallel
with each other.
Mounting of the cables
•
Check that the battery voltage matches the inverter DC input
voltage.
•
Check that the inverter is switched off.
•
Connect the cables to the inverter.
•
Check that the cables are well tightened.
•
Make sure that the battery poles are clean, and that there is a
good electrical contact.
•
Connect the selected cables to the battery.
Note!
Do not interchange the battery cables. It will result in instanta-
neous damage of the inverter.

230V AC
Ensure that the inverter is switched off before connecting an AC
cable to the inverter.
Mount a 3-pole male connector into the 230V AC socket on the
inverter.
The inverter is protected against overload and short circuit. It is
not necessary to mount a fuse at the output of the inverter.
Installation
It is recommended to install the inverter in a dry and dust free environment.
Place the inverter as close as possible to the battery, in order to keep the lengths of the cables between battery and inverter as short
as possible.
Never use the inverter in environments with presence of dust or explosive gases.
The inverter can be mounted on a wall or flat mounted.
Optimum cooling is obtained in a vertical position.
Remote input
The remote input is used to turn the inverter ON/OFF remotely
e.g. through a cars ignition system.
The power consumption of BD150F is usually so big that a
standard battery car would be drained very fast if the engine is
not running.
Note!
The remote switch is positive. Do not touch the housing of the
inverter, with the remote switch terminal, it will damage the
switch.
Monitoring
The inverter is equipped with two LED.
The power LED
Constant light: The inverter is in operation mode.
1 flash:
Overload. The inverter is overloaded.
2 flashes:
High temperature. The inverter is too hot inside,
and will enter standby mode. When the inverter
has cooled down it will restart automatically.
3 flashes:
Short circuit. Switch of the inverter and load.
Check all equipment and find out what caused
the short circuit, before the inverter is restarted.
4 flashes:
Battery can not handle high peak power.
Wrong or defect battery.
The low battery LED
Constant light: The voltage is below 10V DC on a 12V DC
version or below 20V DC on a 24 V DC version.
Check the condition of the battery, check if there
are loose connections.
Eventually charge the battery.
