ADM800 - Electrical Wiring
It is highly recommended that the ADM800 be connected directly to the AC power source, preferably on its own
circuit. The connection should be completed with a UL rated multi-conductor wire (14-18 AWG).
Locate service knockouts on exterior of enclosure and install electrical conduit in the typical manner.
The ADM800 is available in either a 120 or 230 VAC configuration. The unit’s AC voltage rating is marked on
the outside of the enclosure. Do one of the following to connect the AC power leads and ground:
• 120 VAC Installation
Locate AC IN connector T3 and the Ground Stud on the inside of the enclosure (Page
22).
Remove the AC IN connector from the circuit board, and then secure the incoming AC power line (black) and
neutral (white) wires to this connector as shown in the following illustration. Carefully plug the connector back
onto the circuit board.
Using the supplied crimp-on ring terminal, washers, and nuts, connect the AC input ground wire (green) along
with the ground wire connected to the front panel to the unit’s Ground Stud.
• 230 VAC Installation
Locate the AC Input Line Filter’s black and white wires, and the Ground Stud on the inside of the chassis
(Page
22).
Using wire nuts, secure the incoming AC power Line 1 (black) and Line 2 (white) wires to the AC Input Line
Filter as shown in the following illustration.
Using the supplied crimp-on ring terminal, washers, and nuts, connect the AC input ground wire (green) along
with the ground wire connected to the front panel to the unit’s Ground Stud.
