• Installation should always be in accordance with national wiring regulations.
• AC external supply should be protected with an external disconnecting device that has
a contact separation of at least 3 mm. This external AC supply must also be over current
protected. The disconnecting device must always be labeled with rated voltage as well as
rated current.
• The unit’s earth connections must always be connected to the enclosures ground.
• All cables in a permanent installation, must be installed and secured properly to
