To ensure safety requirements the Multi-Mon must be grounded - the
protective ground terminal should be connected to protective earth with a
copper conductor or strap with minimal length (less than 1 m desirable) and
cross-section 5.3 mm
2 (AWG10) at least.
The properly marked external 3-pole disconnect device with circuit-breaker
and a fuse 6A, 600V in every pole should be installed between voltage
measurement terminals and power lines, located as close as possible (less
than 2 m recommended) to the Multi-Mon, as shown in figure 2-5 .
