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 du CNE, le côté négatif du système doit
être mis à la terre par un GFPD à un seul point.
Step 7 - Battery Voltage Sense
The voltage at the battery connection on the TriStar MPPT 150V may differ slightly from the voltage
directly at the battery bank terminals due to connection and cable resistance. The Battery Voltage
Sense connection enables the TriStar MPPT 150V to measure the battery terminal voltage precisely
with small gauge wires that carry very little current, and thus have no voltage drop. Both battery
voltage sense wires are connected to the TriStar at the 2-position terminal located between the push-
button and the positive (+) terminal lug (see figure 2-1).
A battery voltage sense connection is not required to operate your TriStar MPPT 150V 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 voltage sense 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
recommended but not required. Use UL rated 300 Volt conductors. The voltage sense wires may be
pulled through conduit with the power conductors.
Fuse the positive (+) voltage sense wire as close to the battery as possible. Size the fuse based on wire
ampacity - a 1A fuse can be used for #24 wire.
Tighten the connector screws to 5 in-lb (0.56 Nm) of torque.
The maximum length allowed for each battery voltage sense wire is 98 ft (30 m).
Be careful to connect the battery positive (+) terminal to the voltage sense positive (+) terminal. No
damage will occur if the polarity is reversed, but the controller cannot read a reversed sense voltage.
Connecting the voltage sense wires to the RTS terminal will cause an alarm.
If a TriStar meter is installed, check the "TriStar Settings" to confirm the Voltage Sense and the RTS
(if installed) are both present and detected by the controller. MSView
to confirm the voltage sense is working correctly.
Step 8 - Network Connections
Network connections allow the TriStar MPPT 150V to communicate with other controller or comput-
ers. A network can be as simple as one controller and one PC, or as complex as dozens of control-
lers monitored via the internet. Review section 5.0 for more information about networking and the
connection(s) required for your system.
WARNING: Shock Hazard
Never route network cables in the same conduit as the power conductors

Installation
WARNING: Shock Hazard
Only use 300 Volt UL rated communication cable.
AVERTISSEMENT : Risque de décharge électrique
N'acheminez jamais les câbles réseau dans le même conduit que les
conducteurs d'alimentation.
AVERTISSEMENT : Risque de décharge électrique
N'utilisez qu'un câble de communication 300 V homologué UL.
Connect the appropriate network cables to the TriStar MPPT 150V at this time. Access to the network
ports is easier before the power cables are attached. The ports are located inside the conduit wiring
box on the lower circuit board as shown in figure 3-5.

EIA-485 Connection
The four (4) position EIA-485 connector on the TriStar MPPT 150V must be removed to access the
terminal screws. Remove the socket connector by firmly grasping the connector body and pulling
away from the circuit board as shown in Figure 3-6.
