Please keep this user manual for future use. Always follow the precautions, and safety
●
instructions in this document. EG4 will not be liable for any consequence caused by the violation
of the safety regulations, design, production, and usage standards.
Only accessories included with the inverter shipment are recommended for use with the inverter.
●
Modification or unapproved components may result in a risk of fire, electric shock, or injury to
person.
Make sure that existing wiring is in good condition and that wire is not undersized. Do not
●
disassemble any parts of the inverter which are not mentioned in the installation guide. It
contains no user-serviceable parts. See Warranty for instructions on obtaining service. Attempting
to service the inverter yourself may result in a risk of electric shock or fire and will void your
warranty.
Keep away from flammable, explosive materials to avoid possible fires.
●
The installation place should be away from humid or corrosive substances.
●
Authorized service personnel must use insulated tools when installing or working with this
●
equipment.
Never touch either the positive or negative pole of a PV connecting device. Never touch both of
●
them at the same time.
The unit contains capacitors that remain charged to a potentially lethal voltage after the
●
utility, battery and PV supply has been disconnected.
Hazardous voltage will present for up to 5 minutes after disconnection from the power supply.
●
CAUTION-RISK of electric shock from energy stored in capacitor, never perform maintenance on
●
the inverter couplers, utility cables, battery cables, or PV cables while power is applied. After
switching off the PV, battery and utility; wait for 5 minutes to let the intermediate circuit
capacitors discharge before unplugging PV, battery, and utility couplers.
When accessing the internal circuit of the inverter, it is very important to wait 5 minutes before
●
operating the power circuit or demounting the electrolyte capacitors inside the device. Do not
open the device beforehand since the capacitors require time sufficiently discharge!
Please use surge protection devices (SPDs) for PV installation.
