Step 5 - 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 pushbutton and the LED’s (see fi gure 2-1). The RTS is supplied with 33 ft (10 m) of 22 AWG (0.34 mm2)
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.
CAUTION:
!
The TriStar MPPT 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 ne 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
