To wire for power
1
Make sure the i-Vu Open Link’s power switch is in the
OFF
position to prevent it from powering up before
you can verify the correct voltage.
2
Remove power from the power supply.
3
Pull the screw terminal connector from the controller's power terminals labeled
24V ac/dc
and
Ground
.
4
Connect the transformer wires to the screw terminal connector.
5
Apply power to the power supply.
6
Measure the voltage at the i-Vu Open Link’s power input terminals to verify that the voltage is within the
operating range of 21.6 – 26.4 Vac or 23.4 - 28.6 Vdc.
7
Insert the screw terminal connector into the i-Vu Open Link's power terminals.
8
Turn
