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.

•A switch or circuit-breaker shall be included in the building installation

•It shall be in close proximity to the equipment and within easy reach of the operator

•It shall be marked as the disconnecting device for the equipment
