WARNING!
It is mandatory to use appr
opriately sized external fuse in the battery and External
Charger Circuits. If external fuse is not used and reverse polarity connection is made
by oversight, the input section of the unit will be damaged/burnt. Warranty will be
voided in such a situation.
MISE EN GARDE!
Il est obligatoire d’utiliser un fusible externe de taille appropriée à la batterie et les circuits chargeur externe .
Si le fusible externe est pas utilisé et les inversions de polarité est faite par la surveillance , la section d’entrée
de l’unité est endommagée / brûlé . La garantie sera annulée dans une telle situation .
3.5.5 DC Input Connection for Battery
Battery is connected to terminals 1, 2 shown in Fig 3.8. The terminal consists of M10 Stud &
Nut. Tightening torque for the nut is 70 kgf.cm (5 lbf.ft). Sizes of cables and fuses are shown
in Table 3.1. Sizing is based on safety considerations specied in UL-1741 and NEC-2014. See
details under “Notes for Table 3.1”.
3.5.6 DC Input Connection for External Solar Charge Controller
External charger is connected to terminals consisting of M6 Stud (Pitch 1 mm) with Thumb Nut
(3, 4 in Fig. 3.8).
- Max current fed through these terminals should be < 50A
- Use wire size given in Table 3.1.
-
T
ightening torque for the Thumb Nut is 35 kgf.cm (2.5 lbf.ft)
-
Use 70A fuse in series with the Positive wir
e to protect against short circuit along the length
of the connecting wires. Fuse should be close to the Positive Input Terminal 3.
- Please refer to Section 5.4 for details of charging using external solar charge controller.
