Introduction
Thank you for purchase of DAIICHI product.
Please read this instruction manual carefully before use.
Keep this manual for future reference.
Please contact with us in case this manual is lost or damaged.
Safety Precaution
■ Usage environment and conditions
Don't use this product in the following conditions.
① Locations beyond the ambient temperature range (-10...+55 ℃) and humidity range (5...90 % RH).
② Locations with excessive corrosive gas (SO2 / H2S / etc.)
③ Locations with excessive dust.
④ Locations with excessive vibration or shocks.
⑤ Locations with excessive exogenous noise.
⑥ Altitude over 2000 m.
⑦ When measure the following inverter output directly, error will becomes large.
Cycle control, SCR phase angle control, PWM inverter.
■ Outdoor use conditions.
① These products are not a dustproof, waterproof, and splash proof construction.
Please avoid the place with much dust. Please do not install in the place directly exposed to the rain
and water droplets. (IP code:IP40)
② Please do not install in the place directly exposed to the sun even through the glass. Discoloration and
degradation of a name plate, and deformation of the box by the surface temperature rise may caused.
③ Product life may shorten when the daily average temperature exceeds 40 ℃.
■ Mounting and wiring
Please refer to this instruction manual for installation and the wiring.
Please refer to connection diagram for the wiring. An improper connection may cause troubles.
Hot line work is prohibited. There is a risk of explosion by electric shock, device malfunction, burning,
fire, or gas.
Please use an electrical wire size suitable with the rated current.
Use unsuitable size electric wire, which may lead to a fire.
Please carry out coating removal of a covering electric wire by reasonable length. If covering removal
is too long, there is a possibility of short-circuiting with the next electric wire. Moreover, if covering
removal of an electric wire is too short, a mating defect and poor contact may be caused.
Be careful of the short circuit by the exposure of conductor.
Please use it combining the current sensor of this product and exclusive use.
Please use a current sensor within input rated range.
Since a current sensor (exclusive use) is only for low-voltage circuits, it cannot be used for a high-voltage
circuit. Connecting with a high-voltage circuit is dangerous.
When using with a circuit of 600 A or more, please connect the current sensor of the 5 A rated the (CTF-5A)
on the secondary side of the instrument for the current transformer (secondary 5 A).
Primary cable to connect to the current sensor, please use the penetrable insulated wire.
Please do not use non-insulated wire and conductor (bus bar, etc.).
As for the core division surface of a current sensor, characteristics worsen by adhesion of dust or accrual
of rust. Be careful not to attach dirt to a core division surface. When dirty, please clean with a dry cloth.
As for the core division surface of a current sensor, characteristics worsen by adhesion of dust or accrual
of rust. Be careful not to attach dirt to a core division surface.
When dirty, please clean with a dry cloth.
Please do not continuously energized the secondary side of the current sensor in an open state.
However, this product has a built-in protection circuit of the secondary terminal open.
There is no problem in the open in the wiring construction period.
The current sensor has polarity. Please note the time of installation.
