Wiring the Relay Contact
The NPort S9450I 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
S9450I’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 S9450I 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 S9450I unit has two sets of digital inputs: DI 1 and DI 2. Each
DI consists of two contacts of the 8-pin terminal block connector on the
NPort S9450I’s top panel.
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 S9450I’s top panel.
Wiring the Redundant Power Inputs
The NPort S9450I unit has two sets of power inputs: power input 1 and
power input 2.
Take the following steps to wire the redundant power inputs:
1.
Insert the negative/positive DC wires into the N-
and L+ 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 S9450I’s top panel.
