Connections
Power Connection (Top View)
1.
Unscrew & Remove the DC Voltage Input Plug from the top header.
2.
Install the DC Power Cables into the Plug (observing polarity on unit).
3.
Plug the Voltage Input Plug back into the top header.
4.
Tightening torque for the terminal block power plug is
0.22 Nm/0.162 Pound Foot
.
5.
Turn the power on the wire.
6.
Verify the Power LED stays ON (Green).
Note:
It is only safe to turn the power on the wires after the wires have been secured to the device.
WARNING:
Inserting the input plug while the DC power is applied may cause arcing, and damage
the input connector permanently.
ALERTE:
Insertion de la prise d'entrée tandis que l'alimentation en courant continu est appliquée
peut provoquer des étincelles, et endommager le connecteur d'entrée de façon permanente.
Note:
Either V1 or V2 can be connected to power for minimal operation. For redundant power
operation, V1 and V2 plugs must be connected to separate DC Voltage sources. Use wire sizes of
16-10 gauge. The power cord should be limited to less than 3 meters in order to ensure optimum
performance. Redundant power inputs will not balance the power load. Only load from one power
supply is used at a time.
Recommended 24V DC Power Supply, similar to:
DIN-Rail Power Supply 10A, N-Tron NTPS-24-10, DC 24V/10A Ground Connection.
Grounding Techniques for Series 1000 Injectors
The grounding of any control system is an integral part of the design. Optimum noise immunity and emissions are
obtained when the chassis is connected to earth ground via a 12-14 gauge drain wire. The N-Tron series injectors
provide a ground lug that is used to provide a safe grounding path of the device.
