NOTE:
Depending on the country of installation, conductors
identified by the color green, or a combination
of green/yellow, shall only be used for earthing
conductors.
AVERTISSEMENT :
L’appareil n’est pas fourni avec un dispositif GFDI.
Ce
contrôleur de charge doit être utilisé avec un appareil
GFDI externe comme requis par le code local ou les
références
Use copper wire to connect the grounding terminal in the
case, and other dead metal, to earth ground. The grounding
terminal is identified by the ground symbol on the case, just
above the terminal, as shown below:
Figure 3-4. Ground Symbol
Per NEC 690.45 (A) and NEC Table 250.122, minimum sizes
for equipment copper grounding wire are:
• ProStar MPPT-25 10 AWG (5 mm
2
)
• ProStar MPPT-40 10 AWG (5 mm
2
)
Per IEC 62109, minimum sizes for equipment copper
grounding wire are:
• ProStar MPPT-25 7 AWG (10 mm
2
)
• ProStar MPPT-40 7 AWG (10 mm
2
)
OR, of the same, or greater, cross-sectional area as the PV
wires.
WARNING:
Risk of Fire
DO NOT bond DC system electrical negative to
earth grounding terminal on the controller. Per NEC,
system negative must be bonded to earth ground at
only one point, and through a GFPD if required.
AVERTISSEMENT :
Risque d’incendie
NE LIEZ PAS le côté négatif du système à la mise à
la terre au niveau du contrôleur. Selon les exigences
par le code local ou les références
, le côté négatif du
système doit être mis à la terre par un GFPD à un seul
point.
For safety, and effective lightning protection, it is
recommended, and may be required by code, that the
negative conductor of the charging system be properly
grounded. Do not connect the grounding electrode
conductor (GEC) to the case ground terminal. The ProStar
MPPT does not have internal ground fault protection; but
where the NEC requires the use of a ground fault protection
device (GFPD), the system electrical negative should be
bonded through a GFPD to earth ground at only one point.
The grounding point may be located in the solar, or the
battery circuit. For system grounding electrode conductor
sizing requirements, refer to the NEC Section 690.47, or
applicable local regulations or code.
STEP 5:
Battery Connections
-
see diagram below
Be sure that DIP switches 2 and 3 are set for 12 or 24V, as
described in Section 3.2
NOTE:
Before connecting the battery, measure the open-circuit
voltage. It must be over 10 volts to start the controller. If the
system voltage Settings Switches are set to Auto-detect, battery
voltage over 15.5V will be detected as a 24V nominal battery, and
the unit will charge accordingly. The 12/24V auto selection is only
done at start-up.
With the battery disconnect open, connect the battery (+)
and (-) wires from the battery to controller. DO NOT CLOSE
THE BREAKER AT THIS TIME.
