Hardware Installation
Terminal Number
Description
Note
1 PWR1
Line
PWR1 Line
+ is connected, or to the Line terminal
for the AC power source.
2 PWR1
Neutral
PWR1 Neutral
– is connected to the Neutral
terminal for the AC power source.
3 PWR1
Surge
Ground
PWR1 Surge Ground
is connected to the
Chassis
Ground
via a jumper on the terminal block.
Surge
Ground
is used as the ground conductor for all
surge and transient suppression circuitry.
NOTE:
Surge Ground must be disconnected from Chassis
Ground during HIPOT (dielectric strength) testing.
4 Chassis
Ground
Chassis Ground
is connected to the Safety
Ground terminal for AC inputs, chassis ground
connects to both power supply surge grounds via a
removable jumper.
5 NC
No function
6 NC
No function
7 Chassis
Ground
Chassis Ground
is connected to the Safety
Ground terminal for AC inputs chassis ground
connects to both power supply surge grounds via a
removable jumper.
8 PWR2
Surge
Ground
PWR2 Surge Ground
is connected to the Chassis
Ground via a jumper on the terminal block. Surge
Ground is used as the ground conductor for all
surge and transient suppression circuitry. NOTE:
Surge Ground must be disconnected from Chassis
Ground during HIPOT (dielectric strength) testing.
9 PWR2
Line
PWR2 Line
to the Line terminal for the AC power
source.
10 PWR2
Neutral
PWR2 Neutral
is connected to the Neutral
terminal for the AC power source.
For AC Power Input
1.
PWR1 Line should be connected to AC (Line).
2.
PWR1 Neutral should be connected to AC (Neutral).
3.
Surge Ground is 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 protection board.
4.
Chassis Ground should be connected to the AC Ground terminal.
ATTENTION
1.
Equipment must be installed according to the applicable country wiring codes.
2.
Surge Ground MUST be disconnected from the Chassis Ground during HIPOT (dielectric strength)
testing.
3.
All line-to-ground transient energy is shunted to the Surge Ground terminal. In cases where users
require the inputs to be isolated from the ground, remove the ground braid between Surge and
Chassis Ground. Note that all line-to-ground transient protection circuitry will be disabled.
