2. Preparation
2.1 Safety Instructions
WARNING
The installation, service, recycling and disposal of the
inverters must be performed by qualified personnel only in
compliance with national and local standards and
regulations. Please contact your dealer to get the
information of authorized repair facility for any maintenance
or repairmen. Any unauthorized actions including
modification of product functionality of any form will affect
the validation of warranty service; Omnik may deny the
obligation of warranty service accordingly.
DANGER
DANGER due to electrical shock and high voltage
DO NOT touch the operating component of the inverter, it
might result in burning or death.
TO prevent risk of electric shock during installation and
maintenance, please make sure that all AC and DC
terminals are plugged out.
DO NOT stay close to the instruments while there is severe
weather conditions including storm, lighting etc.

5
CAUTION

4.3 Product Identification
You can identify the inverter by the side name plate. Information such as type of the
inverter, as well as inverter specifications are specified on the side name plate. The
name plate is on the middle part of the right side of the inverter housing. And the
following figure is the side name plate example as on Omniksol-2k-TL2.
4.4 Further Information
If you have any further questions concerning the type of accessories or
installation, please check our website www.omniksolar.it or contact our service hotline.

5. Installation
5.1 Safety
NOTICE
NOTICE due to the inappropriate or the harmonized
installation environment may jeopardize the life span of
the inverter.
Do NOT expose to direct sunlight to avoid power derating due to
increase in the internal temperature of the inverter.
Do NOT expose to rain and snow cover to enhance inverter life
time.
The installation site MUST have good ventilation condition.
DANGER
DANGER to life due to potential fire or electricity shock.
DO NOT installs the inverter near any inflammable or
explosive items.
This inverter will be directly connected with HIGH VOLTAGE
power generation device; the installation must be performed
by qualified personnel only in compliance with national and
local standards and regulations.

17
5.2 Mounting Instructions
Omnik inverter is designed for indoors and outdoors installation, Omnik suggests to
install the inverter in basement or garage where there’s no directly sunlight or rain.
Do not install in rooms where people live or where the prolonged presence of people
or animals is expected because of the noise that the inverter makes during operation.
Please mount the inverter in the direction as illustrated above.
Install the inverter in the vertical direction is recommended, with a max.15 degrees
backwards.
For the convenience of checking the LCD display and possible maintenance
activities, please install the inverter at eye level.
Make sure the wall you selected is strong enough to handle the screws and bear the
weight of the inverter.
Ensure the device is properly fixed to the wall.
It is not recommended that the inverter is exposed to the strong sunshine, because
the excess heating might lead to power reduction.
The ambient temperature of installation site should be between -20 °C and +60 °C
( between -4 °F and 140 °F ) .
Make sure the ventilation of the installation spot, not sufficient ventilation may reduce
the performance of the electronic components inside the inverter and shorten the life
of the inverter.
