COMMISSIONING
7.1
SAFETY INSTRUCTIONS
DANGER!
This product contains dangerous voltages that when touched can cause electric shock, burns
or death. All contact safety devices and plates must be fitted when operating.
Ensure that the apparatus has been in a dead condition for at least 5 minutes before any protective
coverings are removed, giving the internal circuits time to discharge.
7.2
PREPARATORY INSPECTION
Check that the equipment is free from damage, correctly fitted and that all the ventilation
openings are free from obstacles.
Check that all cable installations, electrical connections and protective earths are correctly
implemented.
Check that all protective covers are intact and all breakers and fuses are switched off.
Check that the rating plate of the cubical shows a rated voltage that conforms to the battery's
nominal voltage and the rated voltage of the entire DC system.

POWERING UP
7.3.1
DC
First, provide power to the measuring circuit and the auxiliary input power of the monitoring
unit by, for example, connecting a fuse in the battery circuit.
After a few seconds, the operator panel display lights up, and after a few more seconds text
appears on the display. All measurement values are initially reset. The measurement starts after
around 10 seconds. Alarms are disabled during the initial 30 seconds.
Then connect the rectifier to the battery by, for example, connecting a fuse in the battery circuit.
Switch on the DC output MCB for each rectifier module (F31 for module T1, F32 for module T2,
etc).
7.3.2
AC
Unique for cubicle S39 with 440V rated DC voltage and four or more rectifier modules is that
the 230V AC auxiliary power feeding should be switched on first.
Turn on mains input power.
Switch on the AC input MCB for each rectifier module (F11 for module T1, F12 for module T2,
etc).
