3.20 Power Controller
WARNING
High leakage current—earth connection is essential before connecting
power. Verify the integrity of the earth ground terminal of the power
receptacle before attaching the cabinet power controller cable and
applying power. If the continuity of the terminal-to-ground cannot
be verified, supplemental grounding to the cabinet system must be
provided.
Figure 3–11 shows the connector configurations for the power controller.
Figures 3–12 and 3–13 show the front and rear views of the 874-power
controller. The DECArray300 cabinet system utilizes the 874–D and 887–C
models.
The 887–C power controller is using IEC plugs at input and output.
