Grounding the indicator
Ground the indicator certainly. The earth terminal is the rear panel.
Separate this earth line from other ground line like a motor, inv erter or a power source.
Unless the indicator is grounded, it may cause to receive an electric shock, be
happen operation error or catch fire
Use adaptable power cord
Confirm the AC voltage and current of the power cord. If the voltage range of cord is
lower than power line voltage, it may cause of a leak or catching fire. Use
compression terminals to connect the power cord to the terminal of the rear panel.
Fuse
The fuse is installed to prevent the indicator from catching fire.
The indicator is equipped many safety circuits. Therefore, the fuse is not broken in

accessory rubber, the front panel is equivalent to IP-65.
Flammability gas
Do not install the indicator in any flammable gas.
Radiation of the indicator
Space out instruments to radiate heat sufficiently.
Removing the cover
Remove the power cord terminals in the side of the power source before remov ing the
cover to avoid receiving an electric shock.
Do not touch the internal circuit within 10 seconds after turning off the indicator
because of receiving an electric shock.
