Installation
Step 7 - Remote Temperature Sensor
The included Remote Temperature Sensor (RTS) is recommended for effective temperature
compensated charging. Connect the RTS to the 2-position terminal located between the push-
button and the LEDs (see gure 2-1 on p. 13). The RTS is supplied with 33 ft (10 m) of 22 AWG
(0.34 mm
2
) cable. There is no polarity, so either wire (+ or -) can be connected to either screw
terminal. The RTS cable may be pulled through conduit along with the power wires. Tighten the
connector screws to 5 in-lb (0.56 Nm) of torque. Separate installation instructions are provided
inside the RTS bag.
WARNING: Risk of Fire.
If no Remote Temperature Sensor (RTS) is connected, use the TriStar MPPT 600V
within 3m (10 ft) of the batteries. Internal Temperature Compensation will be used if
the RTS is not connected. Use of the RTS is strongly recommended.
AVERTISSEMENT : Risque d’incendie.
Si non Capteur de température distant (RTS) est connecté, utilisez le MPPT ProStar moins de 3m (10 pi)
de les batteries. Compensation de la température interne sera utilisée si la RTS n’est pas connecté.
Utilisation de la RTS est fortement recommandé.
!
CAUTION:
The TriStar MPPT 600V will not temperature compensate charging parameters if the RTS is not
used.
!
CAUTION: Equipment Damage
Never place the temperature sensor inside a battery cell. Both the RTS and the battery will be
damaged.
NOTE:
The RTS cable may be shortened if the full length is not needed. Be sure to reinstall the ferrite
choke on the end of the RTS if a length of cable is removed. This choke ensures compliance with
electromagnetic emissions standards.
!
PRUDENCE :
Le TriStar MPPT 600V 600Vne compense pas la température des paramètres de charges si le
RTS n’est pas utilisé.
!
PRUDENCE : Endommagement de l’équipement
Ne placez jamais la sonde de température dans un élément de batterie. Le RTS et la batterie
seraient endommagés.
REMARQUE :
Le câble de RTS peut être raccourci si la totalité de la longueur n’est pas nécessaire. Assurez-
vous de réinstaller la bobine en ferrite sur l’extrémité du RTS si une longueur de câble est
enlevée. Cette bobine assure la conformité avec les normes d’émissions électromagnétiques.
Step 8 - Battery Voltage Sense
The voltage at the battery connection on the TriStar MPPT 600V may differ slightly from the
voltage directly at the battery bank terminals due to connection and cable resistance. The Battery
Voltage Sense (BVS) connection enables the TriStar MPPT 600V to measure the battery terminal
voltage precisely with small gauge wires that carry very little current, and thus have no voltage
drop. Both BVS wires are connected to the TriStar at the 2-position terminal indicated by #16 in
gure 2-1, on p. 13. No damage will occur if the polarity is reversed, but the controller cannot
read a reversed sense voltage. Connecting the BVS wires to the RTS terminal will cause an
alarm. If a TriStar meter is installed, check the “TriStar Settings” to conrm the BVS and the RTS
(if installed) are both present and detected by the controller. MSView
TM
PC software can also be
used to conrm the BVS is working correctly.
A BVS connection is not required to operate your TriStar MPPT 600V controller, but it is
recommended for best performance. If a TriStar meter will be added to the controller, the
battery voltage sense will ensure that the voltage and diagnostic displays are very accurate.
The BVS wires should be cut to length as required to connect the battery to the voltage sense
terminal. The wire size can range from 16 to 24 AWG (1.0 to 0.25 mm
2
). A twisted pair cable is
recommended but not required. Use UL rated 300 Volt conductors. The BVS wires may be pulled
through conduit with the power conductors. Tighten the connector screws to 5 in-lb (0.56 Nm) of
torque.
The maximum length allowed for each BVS wire is 98 ft (30 m).
Be careful to connect the battery positive (+) terminal to the voltage sense positive (+) terminal.
