Models
The 7xx models have a redundant 10-49 VDC power input (HV (High Voltage) 43-300 VDC options are available
for some models).
Recommended 24 VDC power supply, similar to Red Lion’s P/N NTPS-24-1.3.
For -HV models, recommended 48 VDC power supply, similar to Red Lion’s P/N NTPS-48-2.
Verify that the proper input voltage is connected to the switch before powering on the unit.
Note:
LEDs are described in detail in
.
1.
Unscrew and remove the DC voltage input plug from the power input header.
2.
Install the DC power cables into the plug (observing polarity).
3.
Plug the voltage input plug back into the power input header.
This is the
power disconnect device that must be removed before performing any kind of
service or maintenance on the device.
4.
Tightening torque for the terminal block power plug is 0.5 Nm/0.368 lb/ft.
5.
Verify that the power LED is on (Green).
Note:
When a DC power supply is installed, only one power supply must be connected to power
for minimal operation. For redundant power operation, V1 and V2 inputs must be
connected to separate DC voltage sources. This unit will draw current from both sources
simultaneously. Use 16-28 AWG (0.08mm
²
- 1.31mm
²)
wire when connecting to the power
supply.
Note:
The Fault pins on the power connector can be used for an alarm contact. The current
carrying capacity is 1A at 24VDC. It is normally open and the relay closes when a fault
condition occurs. These pins can be used to connect an external warning device such as a
light in order to provide an external alarm. The conditions for generating a fault condition
(closing the relay) can be configured through software.
