STUDER INNOTEC HP-COMPACT
User manual HP-COMPACT V3.0 E 10
3.6 Pre-installation settings
Before you start with the cabling of the HP-COMPACT you must set the type of battery. In
case sealed-gel batteries are used then you must set the small slide-switch „Equalize“
which is on the front with the connection terminals, in OFF position. In case of „normal“
lead-acid – batteries, these can handle a higher equalizing charge, the same slide switch
can be set in ON position. In case of doubt leave the setting in OFF position.
This will allow an equalizing cycle (higher end of charge voltage) during the next charge
process. Since then equalizing will occur every 25 usual cycles.
3.6.1 Connection to battery
3.6.1.1 On the appliance side
Mount the supplied glands on the battery cable before the setting of the cable terminal. Set
the cable terminal and mount the glands on the appliance. Repeat the process for the sec-
ond battery cable.
Connect the red cable (+)
on the “+ Battery” appliance
connection point according
to the plan below.
Connect the black cable (-)
on the “- Battery” appli-
ance connection point
according to the plan
above.
The supplied fuse (except
with the HPC2512) must
be mounted according to
the plan below.
3.6.1.2 On the battery side
Caution: before connecting the battery, check carefully the voltage and the battery polarity
with a voltmeter. A polarity reverse will seriously damage the inverter (for example: con-
necting a HPC2512 to a 48V-Battery).
Get the batteries ready for connection: suitable terminals, fuse on one of the connection
points, cable in good shape with, if necessary, terminals rightly set. Mount the red cable on
the positive (+) pole, and the black cable on the negative (-) pole of the battery.
While connecting the second cable, a spark due to the charge of the capacities at the input
stage is normal. In the same time an acoustic signal tells that the control processor has
started. All LED’s of the synoptic light during a short time, then the synoptic shows that the
appliance has stopped. The LED “OFF” (13) must be turned on.
After the battery connection, the battery state-of-charge LED shows a 100% capacity dur-
ing 1 to 2 minutes, the necessary time for the processor to compute again the current
state-of-charge of the battery.
If the LED “Battery Low/High” (12) is lighting, the battery voltage is too low. If it is blinking,
the battery voltage is too high. Caution: a battery voltage too high or inappropriate can se-
