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 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.

5.2 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
•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

5.3 Safety Clearance
Observe the following minimum clearances to walls, other devices or objects to
guarantee sufficient heat dissipation and enough space for pulling the electronic solar
switch handle.
5.4 Mounting Procedure
1. Mark 4 positions of the drill holes on the wall according to the wall mounting bracket in the
carton box.
Direction Minimum clearance
Above 30 cm
Below 40 cm
Sides 10 cm

18
2. First, according to the marks, drill 4 holes in the wall. Then, place 4 expansion tubes in the
holes using a rubber hammer. Next, make 4 screws through the mounting holes in the
bracket, then tighten the screws into the expansion tubes. So far, the wall mounting bracket
is fixed already.
3. Align both sides of the radiator on the hooks of the back panel, move the inverter until the
hooks completely into the slot of the radiator.
