STUDER INNOTEC XP-COMPACT
XP-COMPACT V5.3 12/77
3.5 Cabling
Connecting the XP-COMPACT is a very important step of the installation. You must
take care that all connection work is carried out in a clean and correct way and that
under no circumstance 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 Pre-installation settings
Before you start with the cabling of the XP-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
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 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 it is not lit, 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 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 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 defect. Before opening the casing
cover all terminals must be disconnected including the battery. If the XP-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.
3.6.2 Connection to the 230Vac-consumer appliances (AC OUTPUT)
The 230V consumer appliances must be connected to the terminals AC OUTPUT
with cables which cross section has to follow the local rules in force (usually
2.5mm2). Connections are marked as follows “N“ Neutral, “PE“ Earth (connected to
the appliance box), “L“ Live.
Caution: High voltages can be there. Make sure that the XP-COMPACT is
turned off (LED 13 lighting) before the connection.
3.6.3 Connection to the 230Vac Input (AC INPUT)
The 230V-supply from network or from a generator must be connected to the input
terminals AC INPUT with cables which cross section depends on the power source
(usually 2.5mm2). Connections are marked as follows: “N“ Neutral, “PE“ Earth, “L“
Live (connected to the appliance case).
