PowerFlow ERS MINI, Инструкция по установке и эксплуатации, Страница: 17 / 20

10.2 System Testing
PowerFlow E.R.S MINI is an intelligent device with no initial setup required. It automatically detects the
import/export voltage and current, and the size of the connected loads making commissioning simple.
To check correct operation, should there be no export energy at the time of commissioning, remove the
installed CT and re - install it back to front. This will cause ERS to operate backwards, i.e import will be
measured as export and vice versa.
Turn a large load on such as a kettle to simulate export, ERS will detect this, as export, and start to drive
the load connected from the main POWER OUT connection. Ensure this is on and/or calling for heat. The
LED bar should start to illuminate progressively demonstrating operation. Allow the kettle to boil and
switch off, you should observe the display LEDs on ERS MINI switch off.
This is an indication that the device is working correctly.
REMEMBER: Do not forget to change the CT back to the correct orientation following the test
1. E.R.S MINI has been mounted to a secure surface, the correct way up and with adequate
ventilation.
2. All cable runs are correctly fixed and supported and an AC isolator has been installed.
3. The main power cable has been terminated observing the correct pin numbers.
4. Ensure all the terminations inside the consumer unit are correct and the terminals have been
tightened.
5. Ensure earth continuity between the earthing bar inside the consumer unit and one of the
cover fixing screws on the device.
6. Carry out all circuit tests in accordance with BS7671.
7. Ensure the current clamp connector has been terminated observing the correct pin numbers
and is securely clamped around the incoming live supply conductor in the correct location.
8. Check the orientation of the current clamp to ensure the label faces the incoming supply and
that it is installed between the main meter position and the main consumer board.
9. Ensure any safety labelling has been securely fitted in the correct locations.
10. Ensure the customer has been issued with a user manual and has been given an overview of
how their system works and how to use it.
Only energise the system once all of the above has been completed.
