Connections and Installation
4.2.2 For 230 VAC products
•
Depress rocker handle of all circuit breakers to “off” position, Figure 4.2.
•
Connect a 3-conductor AC line cord, Figure 4.1 Item A, to the power entry module(s)
at the rear panel, Figure 4.1 Item B. Cord must be rated equal to or greater than the
rating of the PDU. Power source must also be appropriately sized and have a ground.
•
Connect equipment to AC outputs, Figure 4.1 Item A. Continuous current draw for all
connected units must not exceed the current rating per output group.
CAUTION:
•
Power source for PDU must be properly grounded.
•
Cord for PDU must be rated equal to or greater than the rating of the PDU.
•
Total current for all connected units must not exceed the current rating per input.
4.3 Communication Hook Up
•
For LAN communications plug into the front RJ-45 jack Figure 4.2 Item F. When
connecting to a 10 Base- 10/100 Ethernet LAN hub or router, use a straight-through
LAN cable. Use a crossover cable if connecting the PDU directly to a PC LAN port.
•
For RS-232 to PC or laptop computer, use a straight-through serial cable to the
RS-232 (DB-9S) connector on front panel,
Figure 4.2D.
Palm PDAs connect directly
to the DB-9P connector on the front panel, Figure 4.2E. A null modem is not required.
•
RS-485/RS-422 interfacing is available at rear panel 6 position modular jack (RJ11),
Figure 4.1 Item D. Caution: Do not connect this jack to a telephone network.
•
Consult Factory for additional Assistance with this communication Scheme.
CAUTION:
•
Do not connect any cable to rear RJ11 connector unless the internal configuration of
this connector is known. Damage to the PDU or connecting computing device may
occur.
4.4 Auxiliary Input and Output Connections
•
Temperature probe input, isolated inputs and programmable isolated relay outputs are
connected to header on rear of the unit. Figure 4.1 Item E, shows the location and
designation of the connections. A pluggable mating connector with screw clamp type
terminals is supplied with the unit. Pin-outs are shown in Figure 4.1 Item F.
•
The temperature probe should be of a type using a TMP35, LM35 or equivalent based
and a two wire current based circuit with a 881 ohm scaling resistor.
•
See commands for direct relay control AFFCA, and AFFCB in Section 5 for information
on setting up the programmable relays.
•
See commands AFFW1 and AFFW2 for using the input signals. These signals are
generated when two points on the auxiliary connector are connected or disconnected
from signal ground.
