Installing power and ground cables

NOTICE
Waste inside the cabinet can cause damage or malfunction.
High voltages will be present in the terminal compartment. High voltages can cause
flashover between the electric potential of different conductors, and the electric potential
of a conductor and earth.
Therefore, a minimum clearance of 82 mm must be maintained between a conductor
and earth, and 110 mm between a conductor and the terminals of any other conductor.
