Connecting the Main Power Supply to the Monochrome
Operator Panel Power Supply
You connect the operator panel power supply directly to the main power
supply. Refer to Figure 3B.2 and Figure 3B.3 when performing these steps:
1.
Use the ac power supply cable (C03) to connect terminals AUX-AC
L1 and L2 of terminal block BT04 on the main power supply to
terminals L1 and L2 of terminal block BT02 on the operator panel
power supply.
2.
Connect the chassis ground terminal on the operator panel power
supply to the cabinet’s grounding bus bar.
Important: The chassis ground terminal connects to the operator panel
chassis and designated cable shields. Power supply common is AC
coupled to chassis ground. It is the user’s responsibility to determine if a
direct connection to cabinet ground bus is required.
