regulations.

• The manufacturer strongly advises installers to follow local safety regulations during

commissioning, operation and maintenance of the GEP inverter. Improper operation may result

in electric shocks or damage to equipment and property.

• The installation, maintenance and connection of the inverters must be performed by qualified

personnel, in compliance with local electrical standards, regulations and following the regulations

of the local power suppliers, companies and related authorities.

• If the GEP inverter is unpacked but not put into use immediately, please put it back to the

original package with the desiccant bag and seal it with tape.

• To avoid electric shocks, the DC input and AC output port of the inverters must be disconnected

for at least 5 minutes before performing any installation or maintenance.

• The temperature of some components of the inverters may exceed 60℃ during operation. To

avoid burns, do not touch the inverter during operation. Let the inverter cool before operating.

• Keep children away from the inverter.

• Touching or changing inverter components without following manual instructions may cause

personal injury, damage the inverters and could ultimately invalidate the warranty.

• The electronic components of the inverter could be damaged by static electricity. Appropriate

methods must be adopted to prevent such damage, otherwise the warranty may be null and

void.

• Ensure the output voltage of the proposed PV array is lower than the maximum rated input

voltage of the inverter, otherwise the inverter may be damaged and the warranty may be null

and void.

• When exposed to sunlight, the PV array generates dangerously high DC voltage. We strongly

advise operators strictly follow instructions and avoid actions that put lives at risk.

• The PV modules should have as a minimum an IEC61730 class A rating protection.

• If the equipment is used in a way not authorized by the manufacturer, the equipment built-in

protections may be damaged.

• In order to achieve complete equipment isolation: turn off the AC switch first, then turn off the DC

switch.

• Do not insert or pull the AC or DC terminals when the inverter is in operation.

• An Arc Fault Detector is recommended to be installed on the DC side of an earthing photovltaic

system.

• The inverter can exclude the possibility of DC residual currents to 6mA in the system, Where an

external RCD is required in addition to the built-in RCMU, type A RCD must be used to avoid

tripping.

• The PV is not grounded as default configuration.

To ensure IP65 protection is maintained, please make sure that the inverter is rigorously

packed and its components are sealed properly. GE strongly suggests to install the

inverter at most one day after it has been unpacked. If this is not the case and the

installation takes longer, please re-seal all the unused terminals and ensure that the

inverter and its components are not exposed to water or dust.
