DURING INITIAL POWER APPLICATION
To apply AC power to the IQ DP-4000 for the first time:
1. Verify that the AC power is off.
2. Verify that the line-to-line voltages fall within the
correct range, as noted on the wiring plan drawing.
3. Check that all wiring is correct according to the
wiring plan drawings and that the chassis is
grounded.
4. When possible, lockout any foreign power sources
and disable the IQ DP-4000 until all other machines
or processes are started and thoroughly checked.
5. Restore AC power and verify the operator panel
functions, after an initial delay, as follows:
• The IA Amps LED lights.
• The Display Window shows the actual line
phase A amperes.
