5 OPERATION
5.1 GENERAL
The bulk of the operation is associated to the monitoring unit. This is described in the Manual for
monitoring unit PCM2 . Other operation is detailed in this section.
5.2 MAINS FEED
The mains breaker handles the mains feed to the rectifier modules.
Note that the breaker only cuts the mains feed to the rectifier modules. The
monitoring unit, however, is fed from the battery and thereby continues to work.
WARNING: Note that the breaker for mains feed does not make the equipment
dead. For a total dead state, the mains feed must also be cut externally and the
equipment's DC output disconnected from the battery.
5.3 OPERATOR PANEL
The operator panel is the link between the equipment and the user. It is made up of
a display, a keypad and a LED. Operation is described in the
Manual for monitoring
unit PCM2 .
5.4 RECTIFIER MODULES
There are three LED indicators on the front of the rectifier module.
However, the front panel must be folded out in order for them to be
visible. Their function is as follows:

AC OK - Green -> Mains OK
Off -> Mains power failure

DC OK - Green -> DC OK
Off -> Low DC voltage

ALM - Red -> Alarm
Off -> OK
When the module gives an alarm you have the option of finding out in detail the cause of the
alarm via the operator panel menus, see the
Manual for monitoring unit PCM2 .
The modules are of the “plug-in” type and can in principle be replaced during operation. For more
information, see the
INSTALLATION INSTRUCTIONS section.
