Gate Grounding
● For reference only.
Cooper Clad Ground Rod (not included)
Use an 8 foot, 5/8 inch ground rod, positioned
two feet or less from the post and 2 inches or
less above the ground. Available at local home
center or hardware stores.
NOTE:
No grounding system absolutely
protects against lightning strikes. If installed
correctly, a grounding system will help
minimize damage to your gate operator.
● The gate must be plumb, level, and swing freely on its hinges.
● The gate must move throughout its arc without binding or dragging on the ground.
● Wheels must NOT be attached to the gate.
● Gates over 250 lb. should have ball bearing hinges with grease fittings.
● Post must be secured in the ground with concrete (minimizes twist/flex when the operator is activated).
● Make sure there is a stable area for mounting the gate bracket (this may require the addition of a horizontal or
vertical cross member).
● We recommend you position the operator near the center-line of the gate to keep the gate from twisting and
flexing, and to avoid back-splash from rain.
