19. Notes for cabinet design
 Design always for possible low
voltage test
 Vertical mount of the HRVS-
DN power section
 Keep always the minimum
distance between phase to
phase and earth to phase

of phases
 Fiber optics
 Control module grounded
 Use as much as possible
standard Solcon wiring
diagram
 IP Protection
