EXCESSIVE ELECTROMAGNETIC INTERFERENCE
When the functional ground (FG) terminal is connected, be sure the wire is
grounded. Not grounding the GP unit can result in excessive Electromagnetic
Interference (EMI). Grounding is required to meet EMC level immunity.
Remove power before wiring the GP unit's power terminals.
The DC model uses only 24 Vdc power. Using any other level of power can
damage both the power supply and the GP unit.
Since the GP unit is not equipped with a power switch, be sure to connect a
power switch to the power supply.
Be sure to ground the GP unit's FG terminal.
Failure to follow these instructions can result in death, serious injury, or
equipment damage.
NOTE: The shield ground (SG) and FG terminals are connected internally in the GP
unit.
Make sure the ground wire is either the same or heavier gauge than the power
wires.
Do not use aluminum wires in the power supply's power cord.
If the ends of the individual wires are not twisted correctly, the wires may create
a short circuit.
Wherever possible, use wires that are 0.75 to 2.5 mm
power cord, and twist the wire ends before attaching the terminals.
The conductor type is solid or stranded wire.
Field wiring terminal marking for wire type (75°C [167 °F] copper conductors
only).
