4.5.7 Connecting the AC supply sources

The Xtender is intended to be supplied by alternative voltage sources such as the public grid or a
generator. Check that the rated voltage of the source corresponds to the rated voltage (34) of the
Xtender specified on the nameplate (fig. 1b) tag (34).
The source must be connected to the input terminals marked "AC INPUT" (13) with sufficient wire cross-
section, depending on the power output of the source, and protected by a protection device of the
appropriate calibre. This will be at the maximum 50A for XTH and XTM range and 16A for XTS
appliances.
The terminals are marked in the following way:
N = neutral, L = live
= protective earth (connected to the enclosure of the device).
An additional earthing terminal (17) is present between the two fastening screws at the
bottom of the unit. It can be used instead of a connection on the input terminals of the
device, particularly when cable cross-sections used at the output do not allow the use of a
three-wire cable (live, earth and neutral) through the conduit glands of the connection
cables of the input and output (AC-IN and AC-OUT), or when the earthing of one of the
poles of the battery. PE required using same or greater cross-sections than the battery
cable.

4.5.8 Wiring auxiliary contacts

These contacts are reversing contacts that are potential-free available in XTH and XTM units. On XTS
models, these auxiliary contacts are available on the external auxiliary relay module (accessory)
ARM-02 (see sect. 9.5 – p. 37). The admissible currents and voltages for these contacts are 16 A: 250
Vac/24Vdc or 3 A: 50 Vdc max. The contact is shown as activated when the corresponding LED is lit.
The representation of the contact near the terminals corresponds to the status of the contact when
not activated.
The cabling of these auxiliary contracts depends solely on the chosen application and on the specific
programming applied and cannot be described in this manual.
To dedicate/program particular functions to these contacts, please refer to user manual of the
remote control unit RCC-02/03
The factory-set functions for these 2 auxiliary contacts are covered in the sect. 7.5 – p. 31.
Cable-glands that are not in use must be properly closed. If this instruction is not respected,
the equipment loses its degree of protection (IP54) and dust or small animals may enter the
equipment causing significant damage, which is not covered by the warranty.

4.5.9 Connecting the communications cables

The Xtenders are equipped with a pair of RJ45/8 connectors that allow information transfer via a
communication bus in between devices or accessories that use the proprietary protocol of Studer
Innotec. In this network, all parties in the network are connected in series (chain).
The length of the communication bus cable must not exceed 300 m.
When the Xtender is connected to the remote control RCC-02/-03 or another Xtender compatible
device (VarioTrack, BSP etc.) it is possible that their software versions differ. It is important to harmonize
the software versions of all Xtender compatible products in a system. The update is made by the
remote control RCC-02/-03 from an SD card with a firmware version at least corresponding to the
most recent device.
When connecting the device with other compatible devices (Xtender, VarioTrack, BSP,
RCC, Xcom or other) using the same communication bus, it is highly recommended to
make a software update of all components in the system in order to guarantee its
functionalities. Therefore, before starting the setup of the device, download the latest
software version from our website: www.studer-innotec.com on an SD card. Follow the
instructions in the RCC manual for a successful installation.
