Product Usage Instructions
Installation Regulations
1. Remove the locking pin to allow the instrument to be
opened.
2. When using for the first time, the instrument will not be
blocked by the pin.
3. Position the reading instrument using the DIN rail or the
clamps. The reading direction of the instrument is indicated in the
reference drawing above.
4. Close the instrument using the locking pin. Apply sufficient
pressure to engage the upper half core with the locking lugs.
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 sensitivity of the current measurement is proportional
to the number of passages of the conductors in the hole, if the
loops are not homogeneously distributed a reading error could
occur.

USB PORT
The module is designed to exchange data according to the modes defined by the MODBUS protocol. It has a micro USB connector and can be configured using applications and/or software programs. The USB communication has priority over the RS485 communication. The USB serial port uses the following communication parameters: 38400,8,N,1 The USB communication port responds exactly like the RS485 port with the exception of the communication parameters. During the use of the USB port, the 485 bus will be inactive; it will reactivate automatically a few seconds after the release of the USB port. EASY SETUP is the software to use for the configuration. For further information go to the website on the cover.
SETTING THE DIP-SWITCHES
The position of the DIP-switches defines the Modbus communication parameters of the module: Address and Baud Rate. The following table shows the Baud Rate and Address values according to the DIP- SWITCH setting:
