2.2 Power Supply Wiring and Grounding
2.2.1 AC Power Supply Wiring and Grounding
Figure 4 - Power Supply Inputs
The AC power supply inputs should be connected as follows:
1. +/L should be connected to AC Line/Hot.
2. -/N should be connected to AC Neutral.
3. Surge Ground should be connected to the Chassis Ground via a braided cable or other
appropriate grounding wire. Surge Ground is used as the ground conductor for all surge
and transient suppression circuitry internal to the unit.
4. Chassis Ground must be connected to the AC ground terminal.
NOTES:
1. Equipment must be installed according to the applicable country wiring codes.
2. All line-to-ground transient energy is shunted to the Surge Ground terminal. In cases
where users require the inputs to be isolated from ground, remove the ground braid
between Surge and Chassis Ground. Note that all line-to-ground transient protection
circuitry will be disabled.
