5. Installation
5.1 Safety
5.2 Mounting Instructions
x Omnik inverter is designed for indoors and outdoors installation
x Please mount the inverter in the direction as illustrated above
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.
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.

16
x Install the inverter in the vertical direction is recommended, with a max.15 degrees
backwards.
x For the convenience of checking the LCD display and possible maintenance
activities, please install the inverter at eye level.
x Make sure the wall you selected is strong enough to handle the screws and bear the
weight of the inverter
x Ensure the device is properly fixed to the wall
x It is not recommended that the inverter is exposed to the strong sunshine, because
the excess heating might lead to power reduction
x The ambient temperature of installation site should be between -20 °C and +60 °C
( between -4 °F and 140 °F )
x 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

2. According to the marks, drill 4 holes in the wall. Then place four expansion tubes in
the holes using a rubber hammer. Next make 4 screws through the mounting holes in
the bracket, and then tighten the screws into the expansion tubes. So far, the wall
mounting bracket is fixed already.
