2. Dangers and Warnings

The manufacturer cannot be held responsible if the instructions in this manual are not followed.
The product may only be installed by a professional.
Any intervention on the product must be carried out by a professionnal.
The product must be replaced by a professionnal.
The device must be used in accordance with the specifications in this documentation, otherwise there is a risk of danger. If the device is used in a manner not specified by the manufacturer, the protection provided by the device may be compromised.
No part of the device should be replaced or removed.
Disconnect all power supplies before servicing this unit.
Only accessories conforming to the manufacturer’s specifications should be used (current clamps and connecting cables).
The product must be used at a distance of at least 20cm from user’s body.

3. Installation and Implementation

Positioning of the product

The product must be positioned in a way that does not make it difficult to operate disconnector devices. The product must be installed in an indoor environment.

Mounting on DIN rail

The product must be installed on a 35mm DIN rail fixed in an electrical panel.
Be careful to lock the housing on the DIN rail.

The DIN rail mount consists of 2 parts: a base and a movable and adjustable latch.
It is used to fix the Tyness horizontally or vertically on a DIN rail.

The product can be removed from the DIN rail by manipulating the movable latch with a screwdriver like any other bracket of the same type.

Installation

Before starting the installation of the SQUID Pro, ensure that you use a 24VDC -­ 0.5A power supply positioned at the head to power the device. It is important to maintain and separate the wiring of Low Voltage Safety Circuits (TBTS) from the circuits under dangerous voltage to ensure safety and proper system operation.

When wiring, make sure to observe the polarity of the power connector of the SQUID Pro.

The connection of the measurement clamps to the SQUID Pro is simplified using a quick connector, eliminating the need for tools. Connect the measurement probes to the 12 connectors located on the top and bottom of the device. Make sure not to exceed the maximum current specification for each measurement clamp to avoid the risk of damage or overheating.

To ensure safety during the installation of the clamps, it is imperative to perform this operation when the circuit is de-energized. Use exclusively Ewattch measurement clamps with the reference CURCLAMP-HC-SX, specially designed for optimal compatibility with the SQUID Pro.

The current measurement clamps of the SQUID Pro have a specific orientation, which must be respected. The clamps must be installed so that the arrow on the clamp points towards the energy consumer.

By following these installation and implementation recommendations, you will ensure safe and efficient operation of your SQUID Pro electrical sub-metering system.

There are 2 possible wiring modes with the SQUID Pro:

• Three-phase mode, allowing the measurement of 4 three-phase circuits.

Caution: It is necessary to follow the indications presented in diagram 1 for the wiring.

• Single-phase mode, allowing the measurement of 12 single-phase circuits.

Caution: It is necessary to follow the indications presented in diagram 2 for the wiring.

Tip -­ Rollover Management

To facilitate the management of energy measurement rollovers, the most significant bit of these measurements is used to indicate if a rollover has already occurred. It is never reset to 0. Therefore, during a rollover, the measurement will transition from 0xFFFFFF to 0x800000.

Tip ­- LoRaWAN Payload Decoding

To facilitate the integration of products communicating via the LoRaWAN network, Ewattch has developed a payload decoder available at this address: https://ewattch-documentation.com/?page_id=2215(/?page_id=2215) .
