INSTALLING THE EARTH GROUND
An earth ground refers to the grounding rod and
accompanying equipment ground which need
to be installed to safeguard against potential
electrical shock and damage to personnel and
equipment.
DANGER
The potential for lightning discharge exists with
all gates, fences and gate operators. National
Electric Code (NEC) - Article 250 requires
a separate earth ground in addition to the
required equipment ground.
HySecurity recommends grounding the operator
with a separate earth ground rod (or a similar
device in the case of crash products) to shield
the operator against electromagnetism and other
electrical signals that may cause, erratic operation
with, or damage to, the Smart DC Controller and
other electrical parts.
For earth grounding requirements in the U.S.A.,
refer to the National Fire Protection Association
(NFPA) 780 - Standard for the Installation of
Lightning Protection Systems. Highlights of the
standard include:
NOTICE
Properly grounding the gate operator is critical
to gate operator performance and the life of
its electrical components. Use sufficient wire
size during installation. If you do not ground
the operator with a separate earth ground, you
risk voiding the HySecurity Warranty.
