6.2 Inspection

Frequency inverter is composed of semi-conductive components, passive electronic component and motive component.
All of these components have useful life even under normal working environment, and some of the components can't
work after the life time. There must be maintenance measures such as daily check, regular inspection and component
changing to protect the components. We suggest one regular inspection every 3-4 months after installation. The
inspection period should be shortened in following situations:
High temperature, high altitude;
Start and stop frequently;
AC power supply or load fluctuates obviously;
Environment with serious vibration or impact;
Environment with dust, metal dust, salt, vitriol, chlorine;
Poor storage environment;
Daily Checking
●
To avoid machine damage and to prolong life time, please check the following items every day.
Items
Check if power supply meets the
Power supply
requirement and if there is lack-phase.
No operation under power connecting state. Otherwise, there is danger of electric shock
even death.
Before operation, please cut all related equipments power, ensure that the main circuit DC
current has dropped to safe range. And please operate after 5 mins.
No operation when cover/panel is dismantled. Otherwise there is danger of electric shock.
Do not dismantle the cover or PCB under power connected state. Otherwise there is
danger of electric shock death.
Only professional personnel can maintain or change fittings. Otherwise, there might be
danger.
Do not wear loose clothes when installing, debugging or maintaining. Related protective
tools and safeguard should be adopted.
Tighten screw with specified torque. If main circuit wire connection is loose, there is
danger of overheat fire.
Machine and motor earth must be reliable. Otherwise, there is danger of electric shock
when touching the motor cover.
When operation, please follow the ESD regulations. Otherwise, the inverter may be
damaged.
Do not change the circuit or structure of the inverter. Otherwise, the inverter may be
damaged.
Please confirm the rotate direction when no-load. Wrong direction can cause body injury
or Significant property damage.
Do not use damaged machine. Otherwise, there is danger of accident.
