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 Touch 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:
• The ground rod must be UL listed copper-clad steel,
solid copper, hot-dipped galvanized steel, or stainless
steel. Minimum requirements: ⅝ inch (16 mm) diameter
and 8 feet (244 cm) in length.
• The ground rod is driven into the earth (refer to local
codes for proper depth requirements).
• The ground rod is electrically bonded to the chassis
with a single length of un-spliced 6 AWG copper wire
less than 3 feet (91 cm) long. Due to the large concrete
foundation on crash products, make the necessary
adjustments to accommodate for earth ground
requirements.
• Local jurisdictions may impose other requirements
above the NEC, Article 250 and NFPA 780. Consult
the local codes and regulations regarding requirements
in your area.
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 perator
with a separate earth ground, you risk voiding the HySecurity Warranty.
