Wiring the Relay Contact
The NPort S8000 has two sets of relay outputs: relay 1 and relay 2.
Each relay contact consists of two contacts of the terminal block on the
NPort S8000’s top panel. Refer to the next section for detailed
instructions on how to connect the wires to the terminal block
connector and how to attach the terminal block connector to the
terminal block receptor. The two contacts used to connect the relay
contacts work as follows (see illustration below):
The fault circuit will open if
1.
A relay warning event is triggered, OR
2.
The NPort S8000 is the Master of this Turbo
Ring, and the Turbo Ring is disconnected, OR
3.
Start-up fails.
If none of these three conditions are met, the fault
circuit will remain closed.
Wiring the Digital Inputs
The NPort S8000 unit has two sets of digital inputs: DI 1 and DI 2.
Each DI consists of two contacts of the 6-pin terminal block connector
on the NPort S8000’s top panel. The remaining contacts are used for
the NPort S8000’s two DC inputs. The top and front views of one of the
terminal block connectors are shown below.
Take the following steps to wire the digital inputs:
1.
Insert the negative (ground) or positive DI
wires into the terminals.
2.
To keep the DI wires from getting loose, use a
small flat-blade screwdriver to tighten the wire-
clamp screws on the front of the terminal block
connector.
3.
Insert the plastic terminal block connector
prongs into the terminal block receptor, which
is located on the NPort 8000’s top panel.
Wiring the Redundant Power Inputs
The NPort S8000 unit has two sets of power inputs: power input 1 and
power input 2. The top two contacts and the bottom two contacts of the
6-pin terminal block connector on the top panel are used for the NPort
S8000’s two power inputs. The top and front views of one of the
terminal block connectors are shown below.
Take the following steps to wire the redundant power inputs:
1.
Insert the negative/positive DC wires into the V-/V+ terminals.
2.
To keep the DC wires from pulling loose, use a small flat-blade
screwdriver to tighten the wire-clamp screws on the front of the
terminal block connector.
3.
Insert the plastic terminal block connector prongs into the terminal
block receptor, which is located on the NPort S8000’s top panel.
