Cisco 910 Industrial Router Installation
Verifying Router Operation
Warning:
A readily accessible two-poled disconnect device must be incorporated in the fixed wiring.
Statement 1022
Warning:
This product relies on the building’s installation for short-circuit (overcurrent) protection. Ensure that the
protective device is rated not greater than:
5A.
Statement 1005
Warning:
Installation of the equipment must comply with local and national electrical codes.
Statement 1074
Warning:
Before performing any of the following procedures, ensure that power is removed from the DC circuit.
Statement 1003
Warning:
Only trained and qualified personnel should be allowed to install, replace, or service this equipment.
Statement 1030
Caution:
You must connect the router only to a DC input power source that has an input supply voltage between
12 and 24 VDC. If the supply voltage is not in this range, the router might not operate properly or get damaged.
The Cisco 910 Industrial Router supports dual DC power inputs. The voltage range should be from 12 VDC to 24 VDC.
When the device is installed in an environment requiring AC inputs, use the optional AC power adapter described in
.
To wire the router to a DC input power source, follow these steps:
1.
Locate the power connector.
2.
Identify the positive and return DC power connections on the front panel of the router. The positive DC power
connection is l, and the return is the adjacent connection labeled -.
3.
Measure two strands of twisted-pair copper wire (18-to-20 AWG) long enough to connect to the DC power source.
4.
Using an 18-gauge wire-stripping tool, strip each of the two twisted pair of wires coming from each DC input power
source to 0.25 inch (6.3 mm) ± 0.02 inch (0.5 mm). Do not strip more than 0.27 inch (6.8 mm) of insulation from the
wire. Stripping more than the recommended amount of wire can lead to exposed wire from the power connector
after installation.
5.
Insert the exposed part of the positive wire into the connection l and the exposed part of the return wire
into the connection labeled -. Make sure that you cannot see any wire lead. Only wire
with
insulation
should extend
from the connector.
Warning:
An exposed wire lead from a DC-input power source can conduct harmful levels of electricity. Be sure that
no exposed portion of the DC-input power source wire extends from the power and relay connector.
Statement 122
6.
Use a ratcheting torque flathead screwdriver to torque the power connector captive screws (above the installed wire
leads) to 2.2 in-lb (0.25 Nm).
Caution:
Do not over-torque the power connector captive screws. The torque should not exceed 2.2 in-lb
(0.25 Nm).
7.
Connect the other end of the positive wire (the one connected to +) to the positive terminal on the DC power source,
and connect the other end of the return wire (the one connected to -) to the return terminal on the DC power source.
When you are testing the router, one power connection is sufficient. If you are installing the router and are using a second
power source, repeat
4.
through
7.
using a second power and relay connector.
