Introduction
Simarine high precision SC302T / SC502T digital shunt is an innovative combination
of a shunt and a tank level module.
SC302T / SC502T active combo shunt precisely monitors battery voltage on 12V,
24V, 48V, 60V and 72V systems, battery temperature and continuous currents up
to 300A (400A peak). It’s suitable for a maximal power of 3600W at 12V or 7200W
at 24V. It is equipped with one additional battery voltage input (2 in total).
The integrated tank level module has 2 resistance-type inputs for tank level
monitoring and temperature sensors.
Additionally, the SC302T / SC502T module can also be used for monitoring current
draw of heavy consumers like inverters, bow and stern thrusters, anchor winches
and current generated on generators like shore power chargers, solar panels,
hydro- and wind generators.
SC302T / SC502T innovative protected architecture allows wiring in either negative
(up to 72V) or positive (up to 24V) side.
Safety
Installation of Simarine electronics should be made by electrical specialists with
proper safety equipment. When working with batteries you should wear protective
clothing and eye protection.
CAUTION: Batteries contain acid, a corrosive, colorless liquid that will burn your
eyes, skin and clothing. Should the acid come in contact with eyes, skin or clothing,
wash it immediately with soap under fresh water for at least 15 minutes, and seek
medical support immediately.
CAUTION: Do NOT connect anything to a damaged battery. It could heat up, catch
fire or explode.
CAUTION: Lead-acid batteries can generate explosive gases during operation.
Never smoke, allow flames or sparks near the battery. Make sure to keep sufficient
ventilation around the battery.
CAUTION: When working with a battery, remove all personal metal items like
watches, rings, necklaces and bracelets. Metal items in contact with the battery
terminals might cause a short circuit with a very high electric current, which may
heat up and melt nearby objects and cause severe burns.

Installation
Mounting
1. Remove the shunt cover by unscrewing four screws on top of the shunt
cover.
2. To install the shunt using supplied voltage cables find a place no further
than 3 m away from the battery / battery bank. You can fix the shunt with
the supplied screws using four holes on bottom of the casing.
3. Connect all cables (see section 5.3 Connecting).
4. Place back the shunt cover and screw the four screws on the cover of the
shunt unit.
Cables
Power cable
Minimum power cable cross-section requirement at maximal temperature of
insulation: 70 °C (160 °F).
SiCOM data cable
For the SiCOM connection use the supplied cable. If not possible, use the following
table to determinate the right cable type.
!
Install the shunt unit in a clean dry place, protected from accidental spilling
of liquids.

Connecting
For proper function of Simarine SC302T / SC502T digital shunt it is necessary to take
the following steps:
1. Disconnect the battery / battery bank plus and minus terminal, for safety
reasons.
2. Connect the shunt to Simarine PICO via one of the SiCOM ports to a
Splitter or any other Simarine product in the network.
3. Connect the shunt voltage sensing input to a battery terminal.
4. Connect a temperature sensor to the resistance input on the shunt and
place it near the battery / battery bank (optional)
5. Connect a tank sensor to the resistance or voltage input, depending on the
sensor type (optional)
6. Connect battery / battery bank minus or plus terminal through the shunt’s
IN terminal.
7. Connect all consumers and charging sources to the OUT terminal on the
shunt.
Each correctly connected shunt needs to be configured. This is done via PICO in an
easy way. The configuration process is described in PICO’s manual.
!
Although the shunt can be connected in the positive or the negative line, it
is recommended that the shunt is installed in the negative line if possible.
!
After connecting the shunt, make sure that all the connections between
cables and shunt are tight. Loose connections may cause sparks, heating and
even a fire. It may also damage the shunt.
