Power; Installing The Earth Ground - HySecurity StrongArmPark DC Programming And Operations Manual

How to wire the operator is presented in the Installation Instructions, but detailed information about the
earth and equipment ground, wiring to AC power, DC power considerations and changing the batteries are
described in this section.
I
nstallIng tHe
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 local 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
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.
