Essential Points for Safety

Introduction

１. The Product is not a specified measuring instrument that passed any certification criteria of any designated accreditation organization as prescribed by the Measurement Act. The Product may only be used to provide a rough indication on the amount of power.

３. The Product may malfunction or may be damaged by static electricity. Be sure to remove any static electricity on the body, through such means as touching a metal object nearby, prior to coming into contact with the Product.

２. A touch panel type liquid crystal display has been adopted for the Product. Do not press or hit hard on the surface of the display.

４. Do not connect a telephone line or household LAN cable to the LAN terminal on the Power Monitor and the Wireless Communication Unit. There is danger of the Product malfunctioning.

５.

Insert the AC adapter of the Power Monitor in the power outlet at all times when using the Product.

Removing the AC adapter from the power outlet will prevent the system from obtaining detailed data during such period and result in the omission of graphs and the like.

６. Keep the power supply (breaker for solar power generation) of the Meter turned ON at all times when the Product is in use.

Precautions for Use

７. Reverting the date and time by at least a 15 minute interval into the past will result in the loss of

performance data. Set the date and time correctly.

Example : [A case where performance data is lost] The time is inadvertently changed from 9:15 to 8:45 and then reverted to 9:15. The performance data starting from 8:45 onwards are added to the performance data from 8:45 and the performance data for the period since 8:45 is lost. Lost data cannot be restored.

● Time is changed from 9:15 to 8:45.

● Time is changed from 8:45 to 9:15.

Example : [A case where performance data is not lost] The time is inadvertently changed from 9:28 to 9:18 and then reverted to 9:28. The performance data from 9:15 is fixed as of 9:30 and as such, the performance data is not lost, as long as the time change does not extend to at least a 15 minute interval.

● Time is changed from 9:28 to 9:18.

● Time is changed from 9:18 to 9:28.

8:30　　　　8:45　　　　9:00　　　　9:15　　　 9:30

Data is added to that of 8:45.

Performance data is not lost.

Introduction

８. Do not install the Product in following types of locations:

a) A location with severe fluctuation of temperature.

b) A location that is exposed to

sea breeze (excluding the Wireless Communication Unit for Inverter). c) A location that is exposed to volatile, combustible, corroding or toxic gases. d) A location exposed to direct sun light. e) A location exceeding the operating temperature range (-20 to +50°C) (5 to 35°C for the USB

Wireless Module). f ) A location with altitude of 2,000 meters or higher. g) A location with a large amount of dust (powder dust, sand dust, cotton dust, metal dust, saw dust, straw dust and the like). h) A location covered by metals or metal fittings, metals installed on walls, on top of a metal desk, between metal products or near telephone unit, facsimile unit, personal computer, personal computer peripheral device, television set, microwave oven or induction heating (IH) product.

９. Store the Product in a location with the temperature ranging between -20 and +60°C, with the humidity ranging from 30 to 85% RH.

10. The Product communicates wirelessly.

Install the Product as far away as possible from devices that emit strong radio waves, such as a civil band radio equipment.

11. The communication performance varies depending on the peripheral environment. Verify in advance that the Product is communicating normally when installing the Power Monitor on a wall.

12. Avoid installing the Power Monitor near iron plate or steel reinforcements and try to install the Product with as much clear space as possible.

13. The Product is not compatible with the Total Amount Purchasing System of the Feed-in Tariff Scheme for Reusable Energy.

14. Do not pull out the USB Wireless Module while the power is turned on. Communication with the personal computer and the Meter will no longer be possible.

15. Turn OFF the power breaker for the solar power generation on the power distribution board, remove the AC adapter of the Power Monitor from the power outlet, and contact the retailer where

the Product was purchased when any instance of radio frequency interference occurs with the Product.

16. Do not use any USB Wireless Module other than the one that was bundled with the Product.



１. The value displayed as power consumption may be greater than (or smaller than) the actual value

when the power being generated fluctuates due to fluctuation of sun light or the like. This arises

from the difference in the timing of data acquisition for the power production from the power feed-in

and purchase and is not due to a malfunction of the Product.

２. The amount of power purchased displayed on the Home screen or Log screen may differ from

the power amount indicated on statements from the power company, due to such causes of errors

as those described below:

(1) Errors in measurement: The error arising from the fact that the instrument used by the power company for the purpose of calculating the amount of power purchased is not a specified measuring instrument but instead it is another equipment. (2) Errors in calculation: The error arising from rounding up or rounding off of figures in the calculation and display process of the Power Monitor.
