• Stranded wires to be connected to the ProStar MPPT
terminals should be prepared first with e.g. clamped
copper heads, etc. to avoid the possibility of one
conductor free out of the connection screw, and
possible contact with the metal enclosure.
WARNING:
Solar and battery fuses or DC breakers
are required in the system. These protection devices
are external to the ProStar MPPT controller, and must be a
maximum of 30 amps for the PS-MPPT-25/M and 50 amps
for the PS-MPPT-40/M.
AVERTISSEMENT:
Solaire et batterie fusibles ou
disjoncteurs DC sont nécessaires dans le système.
Ces dispositifs de protection sont externes au contrôleur
MPPT ProStar et doivent être un maximum de 30
ampères pour le PS-MPPT-25/M et 50 ampères pour le
PS-MPPT-40/M.
WARNING:
Installation must comply with all
US National Electrical Code and Canadian Electrical
Code requirments. Breakers and fuses may require lower
ratings than referenced above, so as not to exceed any
specific wire ampacity.
AVERTISSEMENT:
Installation doit être conforme à
toutes les requirments US National Electrical Code
et Code Canadien d'Electricité. Disjoncteurs et fusibles
peuvent exiger des cotes inférieures que mentionnés ci-
dessus de manière à ne pas pour dépasser n'importe quel
fils particulier admissible.
.
WARNING:
Minimum over-current protection
device interrupt ratings must be 2000A for 12V
systems, and 4000A for 24V systems.
AVERTISSEMENT
: Protection contre les
surintensités minimum cotes d'interruption de
périphérique doivent être de 2000 a 12V systèmes et 4000 a
pour les systèmes de 24V.
3.2 Configuration
The DIP switch block shown in Figure 3.1 below is used to
set the operating parameters for the ProStar MPPT.

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, and the detected system voltage will never
change during operation.
Generally, the specfic system voltage is known, and it is best
to set DIPs 2,3 accordingly; the auto-detect setting should
be used only in rare circumstances.
