Disconnect all power and external cables before lifting the system.
•
Ensure that your footing is solid and the weight of the system is evenly
•
distributed between your feet.
Lift the system slowly, keeping your back straight. Lift with your legs, not
•
with your back. Bend at the knees, not at the waist.
•
Depending on the weight of the system, more than one person might be
required to lift it.

The system is designed for connection to TN power systems. A TN power system
is a power distribution system with one point connected directly to earth (ground).
The exposed conductive parts of the installation are connected to that point by
protective earth conductors.
The plug-socket combination must be accessible at all times because it
serves as the main disconnecting device.
