3.6Cabling/wiring
Connecting of the XP-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 that under no circum- stance a cable is connected to a wrong terminal.
Connecting of the XP-COMPACT must be carried out in the following order. In case of dismantling this order must be reversed.
3.6.1Pre-installation settings
Before you start with the cabling of the XP-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.
3.6.2Connection to battery
Get the batteries ready for connection: matching battery terminals, matching fuse on a clamp. Pre- pare 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 into the XP-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 not, press shortly on the switch ON/OFF (19), now OFF should be lit.
On connecting the battery the XP-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 15 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 XP-COMPACT can be destroyed. (For example: connecting a XPC 1400-12 to a 48V-Battery).
Nevertheless if the XP-COMPACT had been connected with reverse polarity, it is highly probable that the fuse inside the casing is broken. Before opening the casing cover all terminals must be disconnected including the battery. If the XP-COMPACT does not function after the change of the fuse and correction of the polarity, it means that it is broken and must be sent for repair.
3.6.3Connecting the 230Vac-Consumer Appliance (AC OUTPUT)
The 230V consumer appliance 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. The Compact is a Class I appliance and the protective earth (PE) have to be connected according to the local rules, in order to insure safety of the installation. The Neutral (Input nor output) is not connected to Earth (see note (1) chap. 2.1).
Caution: High voltage can by there. Be sure that’s the XP-COMPACT is turned off (LED 13 alight) before the connecting.
3.6.4Connecting the 230Vac Input (AC INPUT)
The 230V-supply from network or from a generator must be connected to the screw terminals AC INPUT. 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.
3.6.5Connecting the Solar modules: SOLAR +/- (Only with solar option)
Solar modules are connected on these terminals. Under no circumstance should any other energy source i.e. wind generator be connected to these terminals! Only solar modules must be connected with two cables +/-. Depending on the power of the modules, the cable cross section should be 2.5 up to 6mm2. Before connecting it is necessary to check with a Voltmeter that the voltage of the Module meets the following values:
