Procedure 3: Connecting The Ac Adapter (+3.3 V Dc Power Source); Procedure 4: Connecting The −48 V Dc Power Source - Motorola Canopy T1/E1 User Manual

Canopy T1/E1 Multiplexer
WARNING!
Disconnect power before proceeding.
Follow this procedure to connect the supplied AC adapter (+3.3 v DC power source).

Procedure 3: Connecting the AC adapter (+3.3 v DC power source)

1. Connect the AC adapter to a surge suppression device that meets the standard
specified under
2. Connect the surge suppression device to the building AC power source.
3. Connect the AC adapter to the DC IN port on the rear of the Canopy T1/E1
Multiplexer.
Follow this procedure to connect the to an external −48 v DC power source.
CAUTION!
Ensure correct polarity before connecting external DC supply to Canopy
T1/E1 Multiplexer.
1. Connect the power cables to the terminal strip ensuring the correct polarity is
maintained.
2. Once the Canopy T1/E1 Multiplexer is mounted in its desired configuration,
connect the supplied terminal strip to the back of the unit. Do this by slowly
pushing the terminal strip into the connector on the back of the Canopy T1/E1
Multiplexer.
