the Alternating Current (AC) power to the unit via the prime power input
connector. Note that the specification for the power source is specific to the
unit as follows:
•
For KPA-020IN only – 90 to 135 VAC, 47 to 63 Hz
•
For KPA-040 only – 90 to 270 VAC, 47 to 63 Hz
•
For KPA-080/-100 only – 180 to 270 VAC, 47 to 63 Hz
3.4.2 Chassis Ground Connector
PROPER GROUNDING PROTECTION IS REQUIRED: The installation instructions
require that the integrity of the protective earth must be ensured and that the
equipment shall be connected to the protective earth connection at all times.
Therefore, it is imperative during installation, configuration, and operation that the
user ensures that the unit has been properly grounded using the ground stud
provided on the rear panel of the unit.
A #10-32 stud is provided for connecting a common chassis ground among
equipment.
Note: The AC power connector provides the safety ground.
