Hardware Hookup
Make the necessary connections as called out in the illustration that follows this
paragraph. Refer to “Network Wiring” on page 9 before attaching the 4-position
terminal block connector. Apply power after all connections have been made.
When making connections to the MC2E, consider the following:
• Use Crestron power supplies for Crestron equipment.
• The included cable cannot be extended.

CODE
NOTE: The maximum continuous current from equipment under any external load
conditions shall not exceed a current limit that is suitable for the minimum wire
gauge used in interconnecting cables. The ratings on the connecting unit’s supply
input should be considered to prevent overloading the wiring.
Power Supply
The unit can be powered through the NET connector, the included external power
pack (PW-2410RU) or the optional power pack PW-2420RU. With the
PW-2410RU, the MC2E can provide power to peripheral Cresnet devices (via the
NET connector) up to a total of 13 watts. The PW-2420RU allows the MC2E to
provide up to 38 watts to peripheral Cresnet devices (via the NET connector).
If additional power is needed, Crestron recommends the Crestron CNPWS-75 (75
watts) External Power Supply or equivalent.
CAUTION: When using the included power pack PW-2410RU, the MC2E’s NET
connector can supply 13 watts (maximum) to Cresnet devices. Do not connect
devices that will exceed this rating as damage may occur to the power pack. To
power additional devices from the MC2E’s NET connector, use the optional power
pack PW-2420RU that can supply up to 38 Watts from the NET connector to
Cresnet devices.
NOTE: In larger system configurations that require more than the 24 VDC supplied
by Cresnet, disconnect the +24 VDC wire from the MC2E Cresnet connector and
provide the +24 VDC power to the peripheral devices by an alternate source.
