Connecting Power and Ground
4 14
To connect the 1779-KFM 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 4.10).

Voltage Selection Switch
115V
2.
Set the voltage-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.
