Task 3: Connecting the Power Cables to the CTP2000 Platform on page 105
Task 1: Turning Off All CTP Platform Power
Push all device power switches to OFF to turn off the device.
Task 2: Connecting the Grounding Cable to the CTP Platform (CTP2056 Platform Only)
The CTP2056 device has a grounding stud located in the rear of the chassis, near the
power inputs.
To ground the power unit:
1. Locate the grounding stud.
2. Remove the nuts and locking washers from the grounding stud.
NOTE: We recommenda minimum of 18-AWG ground wire with a ring-style
terminal.
3. Place the grounding cable lead on the grounding stud, and tighten the nuts to secure
the connection.
4. Connect the other end of the ground cable to the appropriate ground termination
lead.
NOTE: When grounding the device, leave a service loop in the grounding
cable to ensure that the grounding cable is the last cable to disconnect
from the shelf if strain is placed on the electrical cables.
