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.
