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.
