INSTALLATION MANUAL

MODULE LAYOUT

Dimensions LxHxD 95 x 75 x 35 mm; Weight: ≈ 150 g; Enclosure: PA6, black

SIGNALS VIA LED ON FRONT PANEL

ASSEMBLY

The device can be mounted in any position, in compliance with the expected environmental conditions.
CAUTION
Magnetic fields of considerable magnitude can alter the measurement: avoid proximity to permanent magnetic fields, solenoids or ferrous masses which induce strong alterations of the magnetic field; possibly, if the zero error is greater than the declared error, try a different arrangement or change orientation.

USB PORT

The front USB port allows easy connection to configure the device using the configuration software. If it is necessary to restore the initial configuration of the instrument, use the configuration software.
Through the USB port it is possible to update the firmware (for further information please refer to the Easy Setup 2 software).

To restore communication on the RS485 port, the cable must be physically disconnected from the USB port.
CAUTION
Check that the device in question is included in the list of products supported by the Easy Setup APP in the store.
When the USB port is connected to a cable, communication on the RS485 port is blocked.

ELECTRICAL CONNECTIONS

WARNING
Disconnect the high voltage before carrying out any work on the instrument.
CAUTION
Switch off the module before connecting the inputs and outputs.
To meet electromagnetic immunity requirements:
– use properly insulated and dimensioned cables;
– use shielded cables for signals;
– connect the shield to a preferred instrumentation ground;
– Keep shielded cables away from other cables used for power installations (transformers, inverters, motors, etc.).

POWER SUPPLY| ANALOGUE OUTPUT| DIGITAL OUTPUT| RS485| MEASUREMENT INPUT
---|---|---|---|---
| | | |

CAUTION
Make sure that the direction of the current flowing through the cable is that shown in the figure (incoming).
To increase the sensitivity of the current measurement, insert the cable several times into the central hole of the instrument, creating a series of loops.
The current measurement sensitivity is proportional to the number of cable passages through the hole.
