AGM300 - Electrical Wiring
It is highly recommended that the AGM300 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 AGM300 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 the AC IN connector T1 and the Ground Stud on the inside of the enclosure (Page
7).
Remove the AC IN connector from the Power Supply 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 enclosure’s lid to the monitor’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 enclosure
(Page
7).
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 enclosure’s lid to the monitor’s Ground Stud.
WARNING – Drilling holes in the AGM300 enclosure will
void the warranty. Please use knockouts provided for
electrical connections.
WARNING - Electrical installation should be performed
by a certified electrician and should comply with all
applicable local, state, and federal electrical safety
codes.
WARNING - Under no circumstances should this
instrument be operated without connection to a
protective ground. Doing so poses a potential shock
hazard and is also a violation of electrical safety
standards applicable to this type of equipment.
