Cautions on safe use
1. Working and storage environments
Don’t mount or store this unit in the following environments. If the unit becomes defective due to the use in an
environment other than specified, it may be repaired for pay even during its warranty period (one year after the
date of delivery).
① Don’t mount or store the unit at a place where the ambient temperature is other than a range of –10 to +55℃ or
the relative humidity is higher than 85
% RH.
② Don’t mount or store the unit at a place where a corrosive gas such as SO
2 , H 2 S, etc. is generated.
Corrosive gas = Sulfur dioxide SO
2 / Hydrogen sulfide H 2 S / etc.
Large current bus / saturable reactor / etc.
③ Don’t mount or store the unit at a dusty place.
④ Don’t mount or store the unit at a place subjected to noticeable vibrations or shocks.
⑤ Don’t mount or store the unit at a place subjected to noticeable external noises.
⑥ If this unit directly measures an inverter output of cycle control, SCR phase angle control or PWM control, an
error may increase due to its operation principle.
2. Cautions on use in an outdoor panel
Be careful with the following items when using this unit in an outdoor panel.
① Don’t mount the unit at a place where it is directly exposed to rain or water drops, otherwise this unit may
become defective because of no water-proof or drip-proof structure.
② Don’t mount the unit at a dusty place.
③ Don’t mount the unit at a place exposed to direct sunlight. Avoid exposing the unit to direct sunlight even
through a glass window.
If the meter is directly exposed to sunlight, the surface temperature of the meter rises and the case may be
deformed if the temperature exceeds 80℃.
④ If the average temperature around the meter exceeds 40℃, the life of the unit may shorten.
3. About dew condensation
If the temperature and humidity of an installation change rapidly when a product is a non-energization, the
waterdrop by dew condensation may adhere to a display inner side. (The display filter and the LCD surface stick
and the pattern of the shape of a circle or an ellipse occur.) This phenomenon is not trouble.
It will disappear, if a control power supply is applied and about 2 hour passes.
4. Mounting and wiring
Mount and connect the unit by a technician while referring to the instruction manual and observing the following
cautions.
 Connect the unit after confirming the connection diagram. An improper connection may cause troubles
such as the generation of a high voltage on the secondary side of its current transformer or burning
of the unit or the occurrence of a fire.
 Don’t perform any connection in a hot line without turning off the power supply in advance, otherwise
an electric shock accident, troubles or burning of the unit, a fire, gas explosion, or other very
dangerous accidents may occur.
 The terminal cover is mounted for preventing an electric shock accident. Mount the terminal cover
without fail after the end of work.

● Caution on connection
(1) Mount the terminal cover without fail for safety after the end of connections.
(2) Separate the input wiring and output wiring from each other without fail, and take a preventive measure against
malfunction due to external noises.
(3) Connect the grounding terminal E (No. 7 terminal) to the ground without fail for enhancing the shield effect.
Keep the grounding resistance between the grounding terminal and the ground to be lower than 100Ω.
(4) Keep a distance of more than 30cm between this unit and the circuit breaker as well as between this unit and the
relay contact signal line.
(5) No protection is necessary for this unit even if the transmission line may be affected by an induced lightning
surge or the like when transmitting an analog output to the receiver. Mount an about 500V arrester or the like
between the line surge protector and the ground as well as between the transmission line and the ground on the
receiver side for the purpose of protecting the devices on the receiver side.
(6) It is recommended to mount a surge killer outside when connecting an inductive load to the pulse output and alarm
output. If no surge killer is mounted, the contact life may shorten.
(7) Please do not earth the output terminal of ZCT.
(8) Please shorten wiring for this product from secondary of ZCT as much as possible. And, in case secondary wiring
becomes close to other large current circuits, please use shielding wire.
(9) In case it measures a leakage current Igr, it is necessary to measure correctly the phase angle of a voltage input
and a zero phase-current input. Wiring of ZCT (primary, secondary) and wiring for this product should check
schematics.
<Caution> When doing Igr measurement by a leakage monitor,
please be careful about polarity of ZCT.

4.2 The kind of display
4.2.1 Measurement display
A measurement value display has the three following types of displays.
The change of the measurement display element of the main monitor by switch operation and the change of the
phase / line display of current / voltage is possible (temporarily).
In a general measurement display, if switch operation is not performed for 10 minutes after changing a display
element, it returns to the original measurement display element automatically.
① General measurement display
Measurement factors, such as current, voltage,
and active power, are displayed.
The measurement value of four factors is
displayed at the maximum.
Setting which always displays a measurement
factor is possible. And, it is possible to
change to a display of the maximum value and the
minimum value, about the measurement factor
which performs holding of the maximum value and
the minimum value by switch operation.
These maximum values and the minimum value are
reset by switch operation (it updates to the
instantaneous value at the time).
In addition, as for the maximum value and the
minimum value, power-supply reset is not cleared
either. And, this display is held by even after
10 minutes of switch non-operation.
