Introduction

SCQ digital shunt module is Simarine’s most versatile module. It can be used to measure voltage, current.
SCQ25 has 4x 25 A integrated shunts capable of measuring voltage up to 35 V DC and continuous current up to 25 A on each shunt.
SCQ50 has 4x 50 A integrated shunts capable of measuring voltage up to 35 V DC and continuous current up to 50 A on each shunt.

Safety

Electrical specialists with proper safety equipment should make installation of Simarine electronics. 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 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.

Overview

A – 4x shunt input
B – 4x shunt output
C – 1x Alarm signal relay
D – 2x SiCOM port

Installation

5.1 Mounting
CAUTION: install the shunt module in a clean dry place, protected from accidental spilling of liquids.

1. You can fix the module with the supplied screws using four holes on both sides of the module.
2. Connect all cables

5.2 Cables
For the SiCOM connection use the supplied cable. If not possible, use the following table to determinate the right cable type.

Cable length	Cable type
< 5m	No limitations
>= 5m	2 x 2 x 0.25 mm2 Twister pair (recommended)

Note: Minimum power cable cross-section requirement at maximal temperature of insulation 70 °C (160 °F).

Connecting

For proper function of Simarine’s SCQ digital shunt it is necessary to take the following steps:

1. Connect the SCQ to Simarine PICO via the SICOM port
2. Connect consumers/generators minus or plus terminal through one SCQ 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.

  CAUTION: 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.
