• To be installed and/or used in accordance with appropriate electrical codes and regulations.
• This product should be installed by a qualified electrician.
PREPARING AND CONNECTING WIRES
Strip the ends of the wires approximately 1/4 in (6 mm). Use care to avoid nicking the conductors. Twist together
the ends of the wires that share a connection. Apply solder only to the ends of the twisted wires. Avoid tinning too
far up the wires or the end becomes brittle.

INTRODUCTION
Refer to the following wiring diagrams when making connections to a Crestron®
CSC-ACEX, CSC-DCEX, CSC-ACCN, CSC-DCCN, CSM-QMT50, or CSM-QMT50-DCEX.
CAUTION: Do not power the device until paper wrapping is removed from the roller
shade assembly.
WIRING CSM-QMT50
Connect the motor pigtail to a dc power source and to Cresnet®. The red wire is +24 V and
the black wire is common.
If desired, use the supplied male and female quick disconnects to create an easy-to-use
disconnection point in the motor’s pigtail wiring.

WIRING CSC-ACCN
Refer to the following illustration for a typical wiring diagram where 120 Vac powers a roller
shade. The roller shade is connected to the CSC-ACCN via RJ-11 cabling. The
CSC-ACCN receives power from Cresnet.

WIRING CSC-DCCN
Refer to the following illustrations for a typical wiring diagram where a CSA-PWS225,
CSA-PWS450, CSA-PWS300, or CSA-PWS600 (all sold separately) supplies Cresnet and
power to the CSC-DCCN. The device can also be powered by a CSA-PWS40 as long as
the 24 and G terminal on the NET port are not connected. The CSC-DCCN can also be
powered with a CSA-PWS40 power pack (sold separately). Power can be applied to either
the G 24 port or NET port. Data is connected to the NET port.
The CSC-DCCN provides power and control to the roller shade.
CAUTION: If the cable needs to be shortened, special care should be taken to ensure
that the cable is properly wired. Follow the color patterns shown in the wiring diagram
below to ensure proper wiring. Improper wiring causes permanent damage to the
connected device and voids the device's warranty.

WIRING CSC-DCEX
Refer to the following illustration for a typical wiring diagram where a CSA-PWS225 or
CSA-PWS450 (both sold separately) supplies power to the CSC-DCEX. The device can
also be powered by a CSA-PWS40, CSA-PWS300, or CSA-PWS600. The CSC-DCEX
provides power and control to the roller shade. Power can be applied to either the front or
back G 24 port.
CAUTION: If the cable needs to be shortened, special care should be taken to ensure
that the cable is properly wired. Follow the color patterns shown in the wiring diagram
below to ensure proper wiring. Improper wiring causes permanent damage to the
connected device and voids the device's warranty.
