STUDER INNOTEC HP-COMPACT

3.6Pre-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.

Cable terminal M8

Bolt M8 x 16

Steel washer

Lugs M10

Screw M8x30 Torque 10Nm

Fuse CF8

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-
