SUMMARY
Environmental conditions
• The higher the humidity in the place where the machine is installed,
the lower the insulation performance of its electric parts becomes.
This results in the premature degradation of the electric parts. Do
not install the machine in such a humid place.
• Where the ambient temperature is not higher than 5°C (41°F), keep
the machine and hydraulic unit energized during the day's work.
• Install the machine in a place where it is not subjected to dust, dirt,
and organic or corrosive gases.
• Keep the machine at least 10 m (33 ft) away from a welder or any
other equipment that may produce electric noise and magnetic fields.
