4.2 Powering on the HI6800 Series Application Controller
The HI6800 Series Application Controllers come with a 24-VDC power supply. An optional
90-240 VAC power supply is available. The controller will power on as soon as it is
connected to the appropriate power source. There is no ON/OFF switch that control power
to the application controller.
Warning:
Do not connect AC and DC power at the same time.
4.2.1 DC Input Power
Use a power-limited 12-27 VDC power supply (Class 2) on the DC input wiring.
DC power should be supplied by a clean primary line
directly
from the DC power source.
Warning:
Do not operate with incorrect line voltage because it will damage
the equipment and/or cause personal injury. Make sure the power source
does not exceed 24 VDC. Do not reverse the ground and hot wires because it
can damage the equipment.
5. Make sure the VDC power source is shut off before installing the wires to the connector.
6. Connect the 24-VDC voltage wire and shield wire to the connector that plugs into the DC
power terminal block at the rear panel.
7. Apply VDC power to the unit.
4.2.2 AC Input Power (Optional)
The optional AC power input is rated from 100 to 240 VAC. Use a clean primary AC power
line directly from the power panel. This line should be supplied with a maximum 20-amp
breaker and should not supply any other equipment.
Be sure the VAC power source is shut off before connecting the wires to the terminal block.
Install a 3-wire, minimum 14 AWG power line to the 3-pin terminal block connector. Using
copper wiring is recommended. Consult local rules and electrical codes.
