Installation
Grounding
The equipment must be grounded to reduce the risk
of static sparking and electric shock. Improper
grounding can cause electric shock. Grounding pro-
vides an escape wire for the electric current.
The G-Barrier must be bonded to an equipotential
grounding system capable of safely carrying any fault
currents with a total resistance from the barrier to the
grounding electrode not exceeding 1 ohm. The ground-
ing connection is not allowed to carry system supply
current in normal operation.

If the DIN rail is bonded to the system ground, then the
barrier connection through the DIN rail is adequate for
system ground.
NOTE: Always bond the G-Barrier to the ground screw.
