INSTALLATION-SITE REQUIREMENTS

SECTION 100-816-202

MARCH 1993

5)If a reading of zero volts on one terminal, and a reading of 100 ~ 120 VAC on the other terminal is obtained, remove both probes from the outlet.

6)Set the meter to the “OHMS/Rx1” scale. Place one probe on the ground terminal, and the other probe on the terminal that produced a reading of zero volts. The reading should be less than 1 ohm.

CAUTION!

If the reading is more than one ohm, then the outlet is not adequately grounded.

7)If the above tests show the outlet is not prop- erly grounded, the condition should be cor- rected (per Article 250 of the National Electri- cal Code) by a qualified electrician before the system is connected.

4.20Alternate or Additional Ground

4.21If the “third wire” AC ground can not practi- cally be improved or if extreme motor noise or other disturbance causes system malfunction, or if local area lightning storms exist, a separate direct ground may be warranted.

4.22Connect a separate earth ground from a cold water pipe or earth grounding rod directly to the FG screw terminal on the DK8/DK16 power supply. See Figure 4-5 of Section 100-816-204(for STRATA DK8) or Figure 5-8 of Section 100-816- 205 (for STRATA DK16).
