Check 24VAC and 24VDC inputs as follows:

1. Ensure power to the unit is turned o.

2. For 24VAC units, ensure the AC Neutral is connected to Terminal 2 and the resistance between

Terminal 2 and the enclosure’s main earth link is 3.0 Ohms, or less.

3. Disconnect the power lead from Terminal 1 (Figure 4-1).

4. Connect a digital volt-ohm-meter red (+) test lead to the disconnected power lead and the black

(-) test lead to Terminal 2.

5. Set the voltmeter to the proper range to measure 24 Volts.

6. Turn on the power.

7. The voltmeter should read 24 Volts ±10%. For 24VDC units, make sure the power lead going to

Terminal 1 is positive and Terminal 2 is negative.

8. Ensure measurement is in DC and not AC voltage.

9. Turn o the power.

10. Disconnect the digital voltmeter and reconnect the wire to Terminal 1.

11. Repeat Steps 1 through 9 for the other 24-Volt units. For units not included in this manual, refer

to the appropriate product datasheet.
