Figure 3. Connecting the PS 1230 Power Supply to an MPA 401 Amplifier

Connect one end of the DC power cord to one of the two pole, 3.5 mm captive screw outlets on the power supply. Connect the other end into the power receptacle on the rear panel of the amplifier, as shown in figure 3 above. The power cord connectors are correctly wired when shipped.

ATTENTION:

•Always use a power supply supplied by or specified by Extron. Use of an unauthorized power supply voids all regulatory compliance certification and may cause damage to the supply and the end product.

•Suitable for use in environmental air space in accordance with Section 300.22.C of the National Electrical Code, and Sections 2-128, 12‑010(3) and 12-100 of the Canadian Electrical Code, Part 1, C22.1.

•Unless otherwise stated, the AC/DC adapters are not suitable for use in air handling spaces or in wall cavities. The power supply is to be located within the same vicinity as the Extron AV processing equipment in an ordinary location, Pollution Degree 2, secured to the equipment rack within the dedicated closet, podium, or desk.

•The installation must always be in accordance with the applicable provisions of National Electrical Code ANSI/NFPA 70 and the Canadian Electrical Code. The power supply shall not be permanently fixed to building structure or similar structure.

•Although the amplifier is plenum rated, the power supply provided with it is not. The power supply must not be placed in the plenum space. Cables to and from the amplifier must also be plenum rated. The DC power cord provided with the unit is not plenum rated.

•The length of the exposed wires in the stripping process is critical. The ideal length is 3/16 inches (5 mm). Any longer and the exposed wires may touch, causing a short circuit between them. Any shorter and the wires can be easily pulled out even if tightly fastened by the captive screws.

NOTE: Do not tin the wires. Tinned wire does not hold its shape and can become loose over time.
