Elem. | Description | Comment | |
a |
| This device allows complete configuration of the installation as well as | |
| remote control | displaying the system behaviour. It is recommended but not | |
|
|
| necessary for the installation to function well. See chapter 6.4.1 – p. |
|
|
| 23. |
b | Battery |
| 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. |
e | Communications | Communications cable. Only an original cable supplied by Studer | |
| cable |
| Innotec may be used. The total length of the communications cable |
|
|
| must not exceed 100 m for 3 x |
|
|
| |
f | Protection devices | A | |
|
|
| 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. |
h | Distribution bar | Positive pole of the battery | |
j | Distribution bar | Negative pole of the battery | |
k | One or more | ||
| or/and | micro- | own regulation system may be used to directly charge the battery. Its |
| hxdro generator | dimensioning does not depend on the Xtender and does not interfere | |
|
|
| with it. |
L |
|
|
|
m | Solar generator | One or more | |
|
|
| system may be used to directly charge the battery. Its dimensioning |
|
|
| does not depend on the Xtender and does not interfere with it. |
r | Remote | control | A control device may be connected to the terminals (7) of the |
| via dry contact | Xtender. See chapter 6.2.12 – p. 21. | |
|
|
| The length of the connection cable must not exceed 5 m. |
t |
| The sensor is placed in immediate proximity to the battery. If the | |
| temperature | installation comprises several Xtenders, a single sensor is connected | |
| sensor |
| to one of the units. See chap. 6.4.2 p.24 |
