NOTES:
• One power supply is included with the transmitter and normally can power both
units.
• If you have removed the ground jumpers (see
page 12) because of ground potential differences, one DTP DVI 330 unit cannot
remotely power the other unit. Each unit requires a local power supply.
Figure 9 shows how to wire the connector. Use the supplied tie-wrap to strap the power
cord to the extended tail of the connector.

CAUTION: Electric shock hazard:
• The two power cord wires must be kept separate while the power supply is
plugged in. Remove power before wiring.
• The length and preparation of exposed wires is important. See the second and
third audio connector
ATTENTION:
•
This product is intended to be supplied by a Listed Power Unit marked "Class 2"
or "LPS," rated 12 VDC, 1.0 A minimum. 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.
•
Unless otherwise stated, the AC/DC adapters are not suitable for use in air
handling spaces or in wall cavities.
• 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 a
building structure or similar structure.
•
Power supply voltage polarity is critical. Incorrect voltage polarity can damage the
power supply and the unit. The ridges on the side of the cord (see figure 9) identify
the power cord negative lead.
