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 operator with a
separate earth ground, you risk voiding the HySecurity Warranty.
