Wiring Requirements
ATTENTION
Safety Fi
rst!
Be sure to disconnect the power cord before installing and/or wiring your NPort S8000.
Wiring Caution!
Calculate the maximum possible current in each power wire and common wire. Observe all electrical codes
dictating the maximum current allowable for
each wire size.
If the current goes above the maximum ratings, the wiring could overheat, causing serious damage to your
equipment.
Temperature Caution!
Please take care when handling
the NPort S8000. When plugged in, the NPort S8000’s internal components
generate heat, and consequently the casing may feel hot to the touch.
You should heed the following:
• Use separate paths to route wiring for power and devices. If power wiring and device wiring paths must
cross, make sure the wires are perpendicular at the intersection point.
NOTE: Do not run signal or communication wiring and power wiring in the same wire conduit. To avoid
interference, wires with different signal characteristics should be routed separately.
• You can use the type of signal transmitted through a wire to determine which wires should be kept separate.
The rule of thumb is that wiring that shares similar electrical characteristics can be bundled together.
• Keep input wiring and output wiring separate.
• Where necessary, it is strongly advised that you label wiring to all devices in the system.
Connecting the Power
Connect the 12-48 VDC power line with the NPort S8000’s terminal block. If the power is properly supplied, the
“Ready” LED will show a solid red color until the system is ready, at which time the “Ready” LED will change to
a green color.
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
S8000’s top panel.
