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.
