SAFETY INSTRUCTIONS

1. Electric Shock Prevention

WARNING

!

While power is on or when the inverter is running, do not open the front cover.

You may get an electric shock.

!

Do not run the inverter with the front cover removed. Otherwise, you may access

the exposed high-voltage terminals or the charging part of the circuitry and get

an electric shock.

!

If power is off, do not remove the front cover except for wiring or periodic

inspection. You may access the charged inverter circuits and get an electric

shock.

!

Before starting wiring or inspection, switch power off, wait for more than 10

minutes, and check for residual voltage with a meter (refer to chapter 2 for

further details) etc.

!

Earth the inverter.

!

Any person who is involved in the wiring or inspection of this equipment should

be fully competent to do the work.

!

Always install the inverter before wiring. Otherwise, you may get an electric

shock or be injured.

!

Operate the switches and potentiometers with dry hands to prevent an electric

shock.

!

Do not subject the cables to scratches, excessive stress, heavy loads or

pinching. Otherwise, you may get an electric shock.

!

Do not change the cooling fan while power is on.

It is dangerous to change the cooling fan while power is on.

!

While power is on, do not move the node address setting switches. Doing so

can cause an electric shock.

2. Fire Prevention

CAUTION

!

Mount the inverter and brake resistor on an incombustible surface. Installing the

inverter directly on or near a combustible surface could lead to a fire.

!

If the inverter has become faulty, switch off the inverter power. A continuous flow

of large current could cause a fire.

!

When a brake resistor is used, use an alarm signal to switch power off.

Otherwise, the brake resistor will overheat abnormally due a brake transistor or

other fault, resulting in a fire.

!

Do not connect a resistor directly to the DC terminals P (+), N (

−

). This could

cause a fire.
