DTP2 T/R 211 • Installation and Operation 12
Power Supply Wiring
A 12 VDC, 1.5 A power supply is provided with the DTP2 211 transmitter. Follow these
instructions to wire the 2‑pole captive screw connector to your power supply:
CAUTION: Risk of minor personal injury. The DC output cables must be kept separate
from each other while the power supply is plugged in. Remove power before wiring.
ATTENTION: Risque de blessure mineure. Les câbles de sortie CC doivent être
séparés les uns des autres tant que la source d’alimentation est branchée. Coupez
l’alimentation avant d’effectuer les raccordements.
ATTENTION:
• Do not connect any external power supplies until you have read the ATTENTION
on the next page.
• Veuillez lire les encadrés «
Attention
» sur la page suivante avant de brancher
une source d’alimentation externe.
NOTES:
• One power supply is included with the transmitter and can normally power both
units, if they are both from the Extron DTP2 series.
•
If the ground jumper (JMP 2) is Open (Off), (see Internal Settings on page 32)
because of ground potential differences, one DTP2 211 unit cannot remotely
power the other unit. Each unit requires a local power supply.
See figure 7 to wire the captive screw connector and secure the power cord to the
extended tail of the connector.

1. Cut the DC output cord to the length needed.
2. Strip the jacket to expose 3/16 inch (5 mm) of the conductors.
3. Slide the leads into the supplied 2‑pole captive screw plug and secure them, using a
small screwdriver.
4. To verify the power cord polarity before connecting the plug, connect the power supply
with no load and check the output with a voltmeter.
5. Use the supplied tie wrap to strap the power cord to the extended tail of the connector.
ATTENTION:
• Always use a power supply supplied and 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.
• Utilisez toujours une source d’alimentation fournie ou recommandée par Extron.
L’utilisation d’une source d’alimentation non autorisée annule toute certification
de conformité réglementaire, et peut endommager la source d’alimentation et
l’unité.
