recommended that you remove the rectifier modules when installing.
6.5.2
Earthing
For earth and screen connections, use the earth bar available in the
connection area, see adjacent figure.
There is an additional earth terminal specially designed for the incoming
mains cable in direct connection to the mains terminal block.
For potential equalization in connection with the cable inlet there is a
hole designed for an M8 bolt intended for a ring cable shoe.
6.5.3
Mains voltage
Check that the outer fuse conforms with the recommendations in the
section.
Connect single phase mains voltage to the terminal marked L and N.
Connect the earth conductor where possible to the adjacent earth
terminal, although this can also be connected to the earth bar.
6.5.4
Battery/Load
Check that the rectifier's rating plate shows the rated voltage that
conforms with the battery's nominal voltage.
Connect the DC system to the terminals and -. Select cables
that are dimensioned for handling the rectifier's rated current.
WARNING!
The rectifier's DC output does not have an internal fuse.
Ensure that there is an external fuse to the battery.
6.5.5
Rectifier modules
The unit can hold up to two rectifier modules. In case of one single module, use the left position
seen from front.
The modules can in principle be replaced during operation. However, it is recommended to start
by disconnecting the mains voltage via the mains breaker at the front.
Press bottom left (see figure) to loosen the module. This releases a handle that can
be pulled out to enable the module to be pulled out of its position.
The module is installed in reverse order by carefully pushing it into place. Move in
the last part by pressing in the handle until it snaps in place.
WARNING!
Check carefully that the rectifier modules have the correct rated voltage. A
mechanical block prevents a 110V-module being incorrectly fitted to the equipment with lower
rated voltage. The block may not be removed. Do not attempt to force the block by, for example,
lifting the module and pushing it at an angle.
6.5.6
I/O unit
All the connections to the monitoring units are grouped in a unit called the
I/O unit. The connectors are pluggable, i.e. they can be removed for better
accessibility when installing. For more information on these connections, see
the
Manual for monitoring unit PCM2
