ROUNDING

Many of our products require a proper ground in order to function properly.

For situations where a proper ground is not available, all you need to do is

drive the grounding rod into the earth to create a ground for any of our prod-

ucts. In some cases, more than one ground rod may be required to meet speciﬁ-

cations. Check your local codes to make sure that the grounding rod will

provide a suitable ground for your location.

The rod itself ships in two pieces. You must connect them to create a suitably

long grounding rod. Be aware, however, that pounding the top of the rod may

make it impossible to ﬁt the coupler (or the wire clamp) over the top of the rod.

Make sure you put the coupler (and wire clamp) onto the rod before you begin

pounding.

Connect the two halves of the rod, using the provided coupler, as

shown below. Note that the bottom of the assembled rod (the end which goes

into the ground) should have a point and the top of the assembled rod should

be ﬂat.

To create a proper ground, you need to drive the rod into the ground. Be aware

that pounding the top of the rod may make it impossible to ﬁt the coupler and/

or the wire clamp over the top of the rod.

Make sure you put the coupler and

wire clamp onto the rod before you begin pounding.

You can secure the ground

wires to the rod after you’ve driven the rod into the ground.

The height of the grounding rod, when fully assembled, may make it difﬁcult

to pound the top. You might want to stand on a ladder when pounding or you

might want to place the coupler onto the bottom rod (ﬂat side into the coupler)

and pound the top of the coupler to drive the rod into the ground a little way.

Then place the second rod into the coupler (point side into the coupler) and

continue driving the assembled rod into the ground as described below.

You may simply place the rod, point side down, in the desired location and

drive it into the ground until only 4-5 inches (10-12 cm) of the rod remains visi-

ble. Or, you may dig a hole about 6” (15 cm) deep and 6“ (15 cm) wide into

which you will drive the rod. Place the rod, point side down, in the desired

location (inside the hole) and drive it into the ground until only 4-5 inches (10-

12 cm) of the rod remains visible. Attach ground wires to the rod at this point.

The advantage of digging the hole is that you may partially ﬁll in the hole once

you have attached ground wires to the rod, thus making less of the rod visible

above ground.

However, you should always leave some portion of the rod vis-

ible above ground.
