Ground The Shelf; Attach The Load Wiring; Figure 7 Grounding Converter Shelf - ABB CPS3200U Product Manual

Ground the Shelf

The next step is to ground the shelf to earth ground. This is an important safety step since each con-
verter relies on this connection for proper ground fault detection
Step
Run and connect the framework ground lead as shown.
Use 6GA conductor minimum and connect to the safety grounding point (frame ground, or main ground bar)
per local practice. Additionally apply NO-OX ID to all bare metal connections if required by local practice. Lugs
are ¼ inch studs on 5/8 inch centers.
Lugs for 6AWG conductor are as follows or available equivalent: T&B 6STR30W
Burndy YAV6C-L2TC14-FX
3. Torque connections to 4 Nm or 35 in-lbs.

Attach the Load Wiring

Provide a circuit from each converter into the designated network telephone pairs. Follow the steps in
the table below to attach load wiring to the CPS3200U shelf.
Step
The wiring assignment information in the following table provides the appropriate connections for each circuit. A
1. cable should be provided with this pinout configuration to terminate the J1 and J2 output connectors on the
CPS3200U Shelf.
•
Wire set Connector: RJ-21 type 50 pin plug:
• 22 AWG solid or stranded AMP 552173-1 or equivalent.
• 24 AWG solid or stranded or 26 AWG solid AMP 229974-1 or equivalent.
• The connector shall be arranged with a right angle housing such that the cable exits to the pin 1 side.
