Z20I4KT/Z20I5KT/Z20I6KT/Z20I4KTL/Z20I5KTL/Z20I6KTL inverter of Beijing
Hua Xin Liu He Investment (Australia) Pty Ltd.(hereinafter referred to
as Zeus Appollo Solar) strictly conforms to related safety rules in design
and test. As electric and electronic equipment, Safety regulation shall be
followed during installation and maintenance. Improper operation may
bring severe damage to the operator, the third party and other properties.
The installation and maintenance of the inverters must be performed by
qualified personnel only in compliance with national and local standards
and regulations.
Before installation and maintenance, DC input and AC output of the
inverter should be cut off beforehand and the inverter cannot be touched
within 10 minutes after power cut-off in case of electric shock.
Partial temperature of the inverter may exceed 60℃during operation,
please do not touch in case of scalding.

3
All electric installation should conform to local electric standard and
permission has to be obtained from local power supply department before
synchronization by qualified personnel.
Children must be kept away from inverters.
Please do not open the front cover of inverter. Apart from wiring terminal,
touching or changing components without authorization may cause
damage to people and inverters. Zeus Appollo Solar may deny the
obligation of warranty service accordingly.
Static electricity may damage electronic components and proper
measures shall be adopted to avoid static electricity.
The output voltage of proposed PV array should be lower than the
inverter maximum rated input voltage; Otherwise, Zeus Appollo Solar will
not undertake any obligations and warranty services.
Please switch off the breaker between PV-Inverter and Grid (utility) firstly
before any service. Or else electric hazards will be caused.
When the photovoltaic array is exposed to light, it supplies a DC voltage to
the PCE.
PV modules should have an IEC61730 class A rating. If the maximum AC
mains operating voltage is higher than the PV array maximum system
voltage, PV modules should have a maximum system voltage rating based
upon the AC mains voltage.
If the equipment is used in a manner not specified by the manufacturer,
the protection provided by the equipment may be impaired.
Completely isolating the equipment should: switch off the DC switch,
disconnect the DC terminal, and disconnect the AC terminal or AC breaker.
Prohibit inserting or pulling the AC and DC terminals when the inverter is
working.

3. Installation
3.1 Mounting Instruction
AIn order to achieve optimal performance, the ambient temperature
should be lower than 45 °C.
BFor the convenience of checking the LCD display and possible
maintenance activities, please install the inverter at eye level.
C Inverters should NOT be installed near inflammable and explosive items.
Any electro-magnetic equipment should be kept away from installation
site.
D Product label and warning symbol shall be visible after installation.
EPlease avoid direct sunlight, rain exposure, snow lay up when installing,
this is better for extending inverter lifetime.

3.3 Equipment Installation
3.3.1 Selecting the installation position
Installation position should be selected based on the following aspects:
The installation method and mounting location must be suitable for the
inverter's weight and dimensions.
Mount on a solid surface.
Select a well ventilated place sheltered from direct sun radiation.
Install vertically or tilted backward by max 15°. The device cannot be

7
installed with a sideways tilt. The connection area must point downwards.
Figure 3.3.1-1
In consideration of heat dissipation and convenient dismantlement, the
minimum clearances around the inverter should be no less than the
following value:
Upward ……………………………………………………………………………….. 300mm
Downward ……………………………………………………………………………….. 500mm
Front ………………………………………………………………………………….. 300mm
Both sides ……………………………………………………………………………….. 500mm
