°
• 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 stron g 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

MC4 Assembly instructions
If, during self assembly, parts and tools other than those stated by MC are used or
if the preparation and assembly instructions described here are disregarded then neither
safety nor compliance with the technical data can be guaranteed.
For protection against electric shock, PV-connectors must be isolated from the
power supply while being assembled or disassembled.
The end product must provi de protection from electric shock.
The use of PVC cables is not recommended.
Unplugging under load: PV plug connections must not be unplugged while under
load. They can be placed in a no load state by switching off the DC/AC converter or
breaking the DC circuit interrupter. Plugging and unplugging while under voltage is
permitted.
It is unadvisable to use non-tinned cables of type H07RN-F, since with oxidised
copper wires the contact resistances of the crimp connection may exceed the permitted
limits.
Disconnected connectors should be protected from dirt and water with sealing
caps.
Plugged parts are watertight IP67. They can not be used permanently under water.
Do not lay the MC-PV connectors on the roof surface.
See the MC catalogue 2 Solar line for technical data and assembled parts.
