Operation Manual
 Instrument for measurement of the electrical parameters should be high quality
instrument with sufficient measuring range.
 Make sure the connection and use of the instrument are correct to avoid arc and
other dangerous situations.

2.3.9 LCD Parameter Setting

Certain LCD settable parameters are closely related to the inverter operation, therefore these
parameters can only be set after reliable evaluation of the system and inverter.
 Improper parameter setting may affect the functionality of the inverter.
 Only qualified personnel can set the inverter parameter.

2.3.10 ESD Protection

The inverter may be damaged irreversibly by electrostatic discharge (ESD) at its
components.
 During the operation of the inverter, please observe all the ESD-related safety
regulations!
 Discharge electrostatic charge by touching the grounded conductor before
contacting any electronic components!

2.3.11 Moisture protection

Penetrating moisture may damage the inverter!

inverter before opening the inverter front door to maintain or service.
Before any service work, observe the following procedures.

Avoid any accidental re-connections.

Verify that no voltage or current is present with appropriate testing devices.

Ground and short-circuit whenever necessary.

Cover possible live parts to avoid accidental contact.

Ensure sufficient escape room.
