Comment

This device allows complete configuration of the installation as well as displaying the system behaviour. It is recommended but not necessary for the installation to function well. See chapter 6.4.1 – p.

23.

The battery capacity is constituted according to figures 5a to 6d based on the required voltage. Note: It is vital that the voltage and the polarity of the battery be checked before connecting to the inverter.

An overload or incorrect polarity could seriously damage the Xtender.

Correct dimensioning of the batteries is essential for trouble free operation of the system. See chapter 4.3.1 – p. 11. f cable Innotec may be used. The total length of the communications cable must not exceed 100 m for 3 x RCC-02/03 or 300 m for a single

RCC-02/03.

Protection devices A fuse-type device, thermal circuit breaker or magnetic-thermal circuit breaker (see fig. 8a) must be installed on at least one of the two battery conductors. It will ideally be placed on the positive pole of the battery and as close as possible to this. The calibre of the device is selected according to the cable section used.

If the negative pole of the battery is not earthed, it must also be protected by such a device.

L m Solar generator One or more solar-powered generators with their own regulation system may be used to directly charge the battery. Its dimensioning does not depend on the Xtender and does not interfere with it. via dry contact t BTS-01 temperature sensor

Xtender. See chapter 6.2.12 – p. 21.

The length of the connection cable must not exceed 5 m.

The sensor is placed in immediate proximity to the battery. If the installation comprises several Xtenders, a single sensor is connected to one of the units. See chap. 6.4.2 p.24
