ATTENTION: Potential Damage to Property.

• Always use a power supply provided 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.

• 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 loca-

tion, 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, article 75 and the Canadian Electrical

Code part 1, section 16. The power supply shall not be permanently ﬁxed to

building structure or similar structure.

• When you connect the power supply, voltage polarity is extremely important.

Applying power with incorrect voltage polarity could damage the power supply

and the ampliﬁer. Identify the power cord negative lead by the ridges on the

side of the cord.

NOTE: Do not tin the stripped power supply leads before installing the captive screw

connector. Tinned wires are not as secure in the connectors and could pull out. Strip

the power cord jacket 5 mm from the end.

CAUTION: Possible Electric Shock.

The two power cord wires must be kept separate while the power supply is plugged

in. Remove power before continuing.

To verify the polarity before connection, plug in the power supply with no load and check the

output with a voltmeter.
