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:
• The ground rod must be UL listed copper-clad
steel, solid copper, hot-dipped galvanized steel, or
stainless steel. Minimum requirements: ½ inch (13
mm) diameter and 8 feet (244 cm) in length.
• The ground rod is driven into the earth (refer to lo-
cal codes for proper depth requirements).
• The ground rod is electrically bonded to the chassis
with a single length of un-spliced 6AWG copper
wire less than 3 feet (91cm) 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 electri-
cal components. Use sufficient wire size during installation. If you do not ground the operator with a separate
earth ground, you risk voiding the HySecurity Limited Warranty.
