5.3 Mounting Instr uctions

• 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

5.5 Mounting Procedure

1) Mark 4 positions of the drill holes on the wall according to the paper installation position
scale packed in the carton box.

2) First, according to the marks, drill 4 holes in the wall. Then, place four expansion tubes in
the holes using a rubber hammer. Next, wring 4 screws into the expansion tubes.

3) First check the 4 holes in the backside of the inverter. Then, lift the inverter carefully, align
the 4 holes in the inverter and the 4 scre ws in the wall, and finally attach the inverter to the
screws slightly.

4) Please carefully check the accessories and original carton to make sure every necessary
part is used and nothing is missing during installation.

Connection procedure by MC4:

Connect the PV modules and inverter using MC4 connectors below. Connect the
positive and negative terminals from the PV modules to positive (+) terminals and
negative (-) terminals on Omniksol.

Connection Procedur e:

1) Switch off the DC breaker and secure against being switched back on inadvertently.

2) Strip the cable 7 mm.

3) Insert striped cable into contact barrel and insure all conductor strands are captured
in the contact barrel.

4) Crimp contact barrel by using a hex crimping die. Put the contact barrel with striped
cable in the corresponding crimping notch and crimp the contact.

5) Insert contact cable assembly into back of the male and female connector. A “click”
should be heard or felt when the contact cable assembly is seated correctly.

21

6) Wrest the cap by using the torque of 2.6~2.9NM.

7) After wrest the cap tightly, align the 2 half connectors and mate them together by
hand until a “click” is heared or felt.

8) When the separation of connector is necessary, use the specified wrench tool to
separate.Please make sure the wedge side of the fingers face the male connector
and push the tool down.Then separate the connector by hand. See below figure.

9) Please use sealing caps for tight sealing of unplugged PV connectors.

If using H4 connector, the operating procedure is similar as that of MC4 connector.
