DA-681 Series Hardware User’s Manual Hardware Installation

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/ DC +

PWR2 Line / DC + is connected to the

positive (+) terminal if the power source is

DC, or to the Line terminal if the power

source is AC.

10 PWR2 Neutral / DC –

PWR2 Neutral / DC – is connected to the

negative (–) terminal if the power source is

DC, or to the Neutral terminal if the power

source is AC.

For AC Power Input

1. PWR1 Line/ DC + should be connected to AC (Line).

2. PWR1 Neutral / DC – 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 PT-7324 unit.

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.
