3.5Cabling/wiring

Connecting of the COMPACT is a very important step in the installation. You must take care that all connecting work is carried out in a clean and correct manner and under no circumstances that a cable is connected to a wrong terminal.

Connecting of the COMPACT must be carried out in the following order. In case of dismantling this order must be reversed.

3.5.1Pre-installation settings

Before you start with the cabling of the COMPACT you must set the type of battery. In case that sealed-gel batteries are used then you must set the small slide-switch „Equalize“ which is on the front with the connecting terminals, to OFF position. In case of „normal“ lead-acid – batteries, these can handle a higher equalizing charge, the same slide switch can be set to ON position. In case of doubt leave the setting in OFF position.

3.5.2Connection to battery

Get the batteries ready for connection: Matching battery terminals, matching fuse on a clamp. Prepare battery cables, if necessary press on cable tabs/shoes. Connect red cable on Plus (+)- Pole and the black cable on the Minus (-) Pole. On connecting the second cable to the battery pole a spark is produced, because for a short time high current flows in the COMPACT to charge the capacitors. For this reason follow strictly the safety measures described in this manual. Check if the red LED OFF (13) is lit. If it is not lit, press shortly on the switch ON/OFF (19), now OFF should be lit.

On connecting the battery the COMPACT needs 1 – 2 Minutes to calculate the actual capacity of the battery. During this time the battery condition is shown as 100% charged. (LED 14 – 17 lit).

If the LED 12 Battery Low/High is lit, the battery charge is too low. If the LED 12 Battery Low/High is blinking, the battery charge is too high.

Caution: With a wrong battery voltage the COMPACT can be destroyed. (for example: connecting a C 1600-12 to a 48V-Battery).

Nevertheless, if the COMPACT had been connected with reverse polarity, it is highly probable that the fuse inside the casing is defect. Before opening the casing cover all terminals must be disconnected including the battery. If the COMPACT does not function after the changing of the fuse and correcting of the polarity, it means that it is defect and must be sent for repair.

3.5.3Connection the 230Vac-Consumer Device (AC OUTPUT)

The 230V consumer device must be connected to the screw terminal AC OUTPUT. For this, use a 3-core cable with a conductor cross section of 2.5mm2. Connections are marked as follows “N“ Neutral, “PE“ Earth, “L“ Live.

Caution: High tension can by there. By sure that’s the compact is turn off (LED 13 alight) before the connection.
