The voltage at the battery connection on the controller may differ slightly from the
voltage directly at the battery bank terminals due to connection and cable resistance.
The remote battery voltage sense connection enables the controller to measure the
battery terminal voltage precisely with small gauge wires that carry very little current,
and thus have no voltage drop. Connect the remote battery voltage sense wires to the
MC1.5.3.81-4L port (11
th
) on the controller (see figure 2-1). Pay attention to “+” and
“-” positions.
A battery voltage sense connection is not required to operate your
controller, but it is recommended for best performance.
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 0.25 to 1.0 mm
2
(24 to 16
AWG). The maximum length allowed for each battery voltage sense wire is 30m. A
twisted pair cable is recommended but not required.
Be careful to connect the battery positive (+) terminal to the voltage sense positive (+)
terminal, the battery negative (-) terminal to the voltage sense negative (-) 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 terminals will
cause an alarm.
Step 3: Network Connection
WARNING: Shock Hazard! The network cables and the power
conductors must be as far away as possible.
NOTE: It is advised to connect the network cables before powering on.
Three kinds of communication are provided as RS-232, CAN BUS and Ethernet. You
can monitor the controller on your PC or update software through RS-232 connection.
The controller is allowed to communicate with remote meter (MT-100) or our other
devices by CAN BUS. The controller also can be monitored via the internet. Refer to
section 6.0 for more information about Ethernet.
