Tripp Lite NGI-S04C2 Owner's Manual page 17

Use copper conductors only, 60/75˚C (140/167°F), tighten to 0.56 N•m

(5 lb•in).
The wire gauge for the terminal block should range between 12~24 AWG.

Redundant Power Input: Choose "Terminal Block (PWR)" as primary power. If you
choose "Terminal Block (PWR)", please refer to option 1, unless follow option 2.
Option 1: Insert the terminal block connector which includes "PWR" and "RPS"

into the terminal block receptor.
Connect power cables to terminal block: Use your finger to press the orange plug on top
of terminal block connector to insert power cables
WARNING
Safety measures should be taken before connecting the power cable. Turn off
the power before connecting modules or wires. The correct power supply
voltage is listed on the product label. Check the voltage of your power source
to make sure that you are using the correct voltage. DO NOT use a voltage greater than
what is specified on the product label. 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 current exceeds the maximum rating, the wiring
can overheat causing serious damage to your equipment.
Please read and follow these guidelines:
• 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 communications wiring and power wiring through 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
You should separate input wiring from output wiring
•
• We advise that you label the wiring to all devices in the system.
Wiring the Alarm Contact:
The Alarm Contact consists of the two middle contacts of the terminal block on switch's
top panel.
FAULT: The two middle contacts of the 6-contact terminal block connector are used to
detect both power faults and port faults. The two wires attached to the Fault contacts form
an open circuit when:
1. The Switch has lost power from one of the DC power inputs.
OR
2. One of the ports for which the corresponding PORT ALARM DIP Switch is set to ON
is not properly connected.
