The standard VPO Unit is rated IP22. It should be installed in a clean and dry area, free from dripping water. It should not be installed in an area prone to flooding.
The VPO Unit should be installed on a level surface in a well-ventilated area.
Every installation will be different and should be considered on its own merits. Installation design must be completed by a suitably qualified electrical contractor.
The VPO Unit is typically installed after the Supply Meter on the incoming mains supply feed and before the main switchboard.
The Mains Supply must be isolated before installation of the VPO Unit.
