Installing the PLC2/DHII Interface
Chapter 4

To connect the PLC-2/DHII interface to power and ground, follow these
steps:
1.
Pull the removable frame out to the switch-setting position. This
exposes the power-selection switch on the right side of the
removable frame assembly (Figure 4.12).

If you connect ii5V AC
input power, slide
the switch up.
If you connect 230V AC
input power, slide
the switch down
2.
Set the power-selection switch to correspond to the level
(115V/230V) of the AC power source.
3.
Push the removable frame back to the operating position.
4.
Tighten the four thumbscrews on the front of the interface. The
thumbscrews must be tight to ensure that AC power is not
interrupted by the interlock switch on the power-supply board.
5.
Lock open the main disconnect switch to remove all power to the
enclosure.
WARNING: Do not attempt to connect power conductors to the
power terminals without first locking open the main disconnect
switch. Failure to heed this warning could cause you to receive
a dangerous electrical shock.
6.
Connect the GND post on the removable frame to the central ground
bus. The central ground bus must connect to the grounding electrode
