DA-710 Series HW User’s Manual Hardware Installation
(dielectric strength) testing.
9 PWR2 Line/ DC +
PWR2 Line / DC + is connected to the positive (+) terminal
if the power source is DC and 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 and 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 computer unit.
4. Chassis Ground should be connected to the AC Ground terminal.
ATTENTION
1. Equipment must be installed according to the applicable national 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. If you need to
isolate the inputs from the ground, remove the ground braid between Surge and Chassis
Ground. Note that all line-to-ground transient protection circuitry will be disabled.
For DC Power Input
The DA-710 series low voltage DC power supply features reverse polarity protection and dual
independent inputs. The dual power inputs allow the connection of two DC sources with the same
nominal voltage to provide redundant power supply inputs. The DC source must be connected to
the DC inputs according to the polarity markings on the unit.
ATTENTION
1. Equipment must be installed according to the applicable national wiring codes.
2. Surge Ground should be connected to Chassis Ground via a braided cable or other
appropriate ground wire.
3. Chassis Ground must be connected to a grounded surface or object.
4. All line-to-ground transient energy is shunted to the Surge Ground terminal. If you need to
isolate the inputs from the ground, remove the ground braid between Surge and Chassis
Ground. Note that all line-to-ground transient protection circuitry will be disabled.
