Allied Telesis AT-WDRPS-80 - Manual (Page 2)

Wiring the AT-WDRPS-80 Power Supply
Warning
As a safety precaution, a 10 Amp circuit breaker should be installed at the
supply end of the cable to be used with this LAN equipment.
ALWAYS connect the wiring to the LAN equipment first before connecting
the wiring to the breaker. To avoid the danger of physical injury from
electrical shock, do not work with HOT feeds. Always be sure that the
breaker is in the OFF position before connecting the wiring to the breaker.
Note
A tray cable is required to connect the power source if the unit is powered by
centralized DC power. The tray cable must be UL listed Type TC tray cable and
rated at 600 V and 90 degree C, with three conductors, minimum 14 AWG.
1. On the rear side of the chassis is a DC terminal block labeled POWER SUPPLY B.
Starting from the left side of the terminal block, identify the positive, frame
ground, and negative terminals using either the diagram adjacent to the
terminal block or the illustration here:
2. With a 14-gauge wire-stripping tool, strip the three wires in the tray cable
coming from the DC input power source to 8 mm
±
1 mm (0.31 in
±
0.039 in).
Warning
Do not strip more than the recommended amount of wire. Stripping more
than the recommended amount can create a safety hazard by leaving
exposed wire on the terminal block after installation.
8 mm ± 1 mm
(0.31in ± 0.039 in)
3. Connect the frame ground wire to the terminal marked with the ground
symbol by inserting the wire into the terminal and tightening the connection
with a flathead screwdriver.
Warning
When installing this equipment, always ensure that the frame ground
connection is installed first and disconnected last.
4. Connect the positive feed wire to the terminal block marked (+).
5. Connect the negative feed wire to the terminal block marked (-).
Warning
"Safety Hazard"- Check to see if there are any exposed copper strands
coming from the installed wires. When this installation is done correctly
there should be no exposed copper wire strands extending from the
terminal block. Any exposed wiring can conduct harmful levels of electricity
to persons touching the wires.
6. Secure the tray supply cable near the rack framework using multiple cable ties
to minimize the chance of the connections being disturbed by casual contact
with the wiring. Use at least four cable ties separated four inches apart with
the first one located within six inches of the terminal block.
Note
This system will work with a positive grounded or negative grounded DC
system.
