Introduction

Precautions for Use
7
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. 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

13. Check that the connected current sensor and the current sensor cable connector are connected correctly.
12. The current sensor has polarity. Install so that the power company side of the current sensor is
on the systems side, and the indoor side is the master short circuit breaker side.
11. Incorrect orientation or installation site of the current sensor, and incomplete locking, will prevent
accurate measurements. Further, dropping or applying shock to the unit will also prevent accurate
measurements.
14. The Product is not compatible with the Total Amount Purchasing System of the Feed-in Tariff
Scheme for Reusable Energy.
15. This product can monitor maximum 3 inverters at one time.
16. 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.
17. 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.
18. Do not use any USB Wireless Module other than the one that was bundled with the Product.
19. Make sure that the construction is such that abnormal rated current (100A) does not flow to the
current sensor that has been installed.
8
６. 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.
７. Store the Product in a location with the temperature ranging between -20 and +60°C, with the
humidity ranging from 30 to 85% RH.
８. 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.
９. 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.
10. Avoid installing the Power Monitor near iron plate or steel reinforcements and try to install the
Product with as much clear space as possible.

Diagram of the power meter seen side-on
This section explains the creation of voltage detection cables.
■ Creation Method
1. Prepare VCTF cables (cable diameter 1.25mm2).
2. Process the cable so that its bare exposed length before machining is 5.5mm to 5.6mm.
(See diagram below.)
3. Crimp the cables for the end crimp terminals in the box as described below.
When crimping, be careful, as it may not be possible to tighten the screws correctly if the bare
wires protrude more than 1mm from the calking.
Pass the isolation cap through the cable before crimping; after crimping,
mount so that the calking of the end crimp terminal is concealed.
5.5ｍｍ〜6.5ｍｍ
Wire diameter: 1.25mm2
Using as is in the condition shown above creates loose screws and a gap between the end crimp
terminal and power input terminal block due to insufficient screw tightening, which causes a
defective connection.
