DANGER
DANGER to life due to potential fire or electricity shock.
DO NOT install 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.
NOTICE
NOTICE due to the inappropriate or the harmonized
installation environment may jeopardize the life span
of the inverter.
Installation directly expose under intensive sunshine is not
recommended.
The installation site MUST have good ventilation condition.

5.3 Mounting Instructions
•Omnik inverter is designed for indoors and outdoors installation
•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 -25 °C and +60 °C
( between -13 °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
