VERIFICATION OF INSTALLATION
ATTENTION
Use only tools and equipment with non-conducting handles when working on
electrical devices.
After connecting the unit to the mains supply, the green LED on its cover should
light up indicating that the controller is supplied.
Safe operation depends on proper installation. Before start up, ensure the following:
■
The mains supply is connected correctly;
■
Protection is provided against electrical shock;
■
The cables are the appropriate size and fuse-protected;
■
There is sufficient air flow around the unit.
s
ATTENTION
The unit is supplied with electrical energy at voltages high enough to inflict personal
injury or threat to health. Take the relevant safety measures.
ATTENTION
Disconnect and confirm that there is no live current flowing to the unit before servicing.
ATTENTION
Avoid exposing the controller to direct sunlight!
