Installation
3.5.0 Making DC Side Connections
The following DC side connections are required to be made
[See Figs 3.8(a) & 3.8(b)]
:
48VDC battery bank is connected to the battery input terminals
[1 & 2 in Figs 3.8(a) & 3.8(b)]
. The terminals are
provided with protective covers – RED for Positive
[1(a) in Figs 3.8(a) & 3.8(b)]
and BLACK for Negative
[2(a) in Figs
3.8(a) & 3.8(b)]
. Fit these covers once connections have been made.
For general details on sizing and charging of
batteries, please refer to Section 1.4 under "General Information-Lead Acid Batteries".
Use appropriate external fuse (
Refer to Table 3.1
) within 7” of battery Positive terminal.
External Charging Source (
e.g. Solar Charge Controller
) is connected as follows:
o
Red and Black Rubber Protection Covers
[3a, 4a in Fig 3.8(b)]
have been provided (
See Section 2.6
) to protect
bare portions of the Positive and Negative cable ends and connectors for External Charging Source
o
Insert the Red Protection Cover through the Positive cable end
o
Insert the Black Protection Cover through the Negative cable end
o
After the cable ends are connected to the External Charger Input Connectors
[3, 4 in Fig 3.8(a)]
, slide the
Rubber Protection Covers over the Input Connectors. Ensure that any bare portion is fully covered and
insulated
[See 3a & 4a in Fig 3.8(b)]
o
Ensure that the rated charging current capacity of the external charger does not exceed 100A
Battery Temperature Sensor EVO-BCTS is connected to the RJ-45 Jack
[6 in Figs 3.8(a) & 3.8(b)]
. See Section 2.5
for installation details.
DC Side Grounding Connector
[5 in Figs 3.8(a) & 3.8(b)]
is connected to the Earth ground / system ground using
minimum AWG #6 wire size.
3.5.1 Preventing DC Input Over Voltage
It is to be ensured that the DC input voltage of this unit does not exceed 68 VDC to prevent permanent damage to
the unit.
3.5.2 Preventing Reverse Polarity On The Input Side
!
CAUTION!
When making battery connections on the input side, make sure that the polarity of battery connections
is correct (
Connect the Positive of the battery to the Positive terminal of the unit and the Negative of the
battery to the Negative terminal of the unit
). If the input is connected in reverse polarity, external DC fuse
in the input side will blow and may also cause permanent damage to the inverter.
Damage caused by reverse polarity is not covered by warranty.
!
ATTENTION!
Au moment de faire les connexions de la batterie sur le côté entrée, assurez-vous que la polarité des
connexions de la batterie est correcte (Connecter la borne positive de la batterie à la borne positive
de l'unité et la valeur négative de la batterie à la borne négative de l'appareil). Si l'entrée est reliée à
l'inversion de polarité, DC externe fusible dans le côté d'entrée fera fondre et peut également causer
des dommages permanents à l'onduleur.
Dommages causés par l'inversion de polarité n'est pas couvert par la garantie.
