3.5.3 Transient Protection For 5083/5084 Panels

The AC lines are the most common source of transient or lighting damage in electronics. The

transient protection on the 5083 and 5084 control panel will only work if the panel is correctly

earth grounded.

Warning: To avoid risk of electrical shock, you may wish to have a licensed electrician ground the electrical

outlet.

3.5.4 How to Verify Earth Ground

To verify earth ground at the AC outlet the 5083/5084 control panel is powered from, use the

following steps:

1. Measure the AC voltage between the center ground post and each side of the outlet (see A

& B in Figure 3-6). You should read approximately 120 VAC at measurement point B and

nominal VAC at measurement point A.

Figure 3-6 Outlet Voltage Measurement Points

2. Measure the voltage between the two slotted holes. It should be equal to the voltage read-

ing at measurement point B. (See Figure 3-6.)

If these voltages are not equal, the outlet does not have a proper earth ground.

3. Ground the outlet by running a wire (18 gauge or higher) to a good earth ground.

The wire should be of equal or greater diameter to the wires used to feed the outlet. It may

be necessary to have a licensed electrician ground the outlet.
