1�- VERIFICATION UPON RECEPTION

Check the following points upon receiving the device:

a) The device meets the specications described in your order. b) The device has not suffered any damage during transport. c) Perform an external visual inspection of the unit prior to switching it on. d) Check that it has been delivered with the following:

- An installation guide,

If any problem is noticed upon reception, immediately contact the transport company and/or CIRCUTOR's after-sales service.

2�- PRODUCT DESCRIPTION

The CEM-C6 static single-phase energy meter measures class 1, with multifunction, RS-485 communications and DIN rail standard installations. It is the ideal solution for residential and commercial installations.

The device features:

- The meter can read these data during the denite time period and analysis the quality and load condition of user’s grid.

- DIN rail standard installation size.

- Only 18 mm wide, can up to 100A.

- RS-485 communication, protocol: IEC1107 or Modbus-TRU Mode.

- Multi-tariff function� The user can set time period through RS-485 communication, then the meter will measure the energy of each different time period.

- Meter has 3.6V Lithium battery, which is used to support multy-tariff function. And the precision of RTC is better that 0.5s/day.

- Blue LCD backlight allows the meter to be read in low light conditions.

- Accurately measure fordward and reverse energy.

3.1.- PRELIMINARY RECOMMENDATIONS

In order to use the device safely, it is critical that individuals who handle it follow the safety measures set out in the standards of the country where it is being used, use the necessary personal protective equipment, and pay attention to the various warnings indicated in this instruction manual.

The CEM-C6 device must be installed by authorised and qualied staff.

The measuring systems switched off before handling, altering the connections or replacing the device. It is dangerous to handle the unit while it is powered.

Also, it is critical to keep the cables in perfect condition in order to avoid accidents, personal injury and damage to installations.

The manufacturer of the device is not responsible for any damage resulting from failure by the user or installer to observe the warnings and/or recommendations set out in this manual, nor for damage resulting from the use of non-original products or accessories or those made by other manufacturers.

If an anomaly or malfunction is detected in the device, do not use the device to take any measurements.

Inspect the work area before taking any measurements. Do not take measurements in dangerous areas or where there is a risk of explosion.

Disconnect the device from the power supply before maintaining, repairing or handling the device's connections. Please contact the after-sales service if you suspect that there is an operational fault in the device.
