AC Outlets
There are four AC outlets on the OIS/OIC power entry panel.
Three are located on the rear for the colour monitor, the com-
puter, and the main power supply.
NOTES:
1.
The AC outlets on the OIS/OIC are wired for 120 VAC or
240 VAC. Make sure that the devices using these outlets are wired
for the correct voltage.
2.
Do not connect motors, lights, or test equipment to the AC out-
lets. Electrical noise may cause data to be lost or changed.
AC Wiring
The following steps outline the required procedure to install and
power up the IIOIS12/IIOIC12. Observe and follow all related
safety procedures when doing these steps (Figure
NOTES:
1.
Turn power off before installing or removing NIU modules
(IIOIS12 only).
2.
Before removing a module from the multibus chassis or perform-
ing maintenance on equipment containing static sensitive devices,
read
HARDWARE SETUP ELECTROSTATIC DISCHARGE (ESD)
in this section.
1. Turn off the breakers for the AC supply power and verify
that no power is present to the OIS/OIC when making wiring
connections.
2. Open the front door of the OIS/OIC cabinet. This provides
access to the terminals needed for wiring to the INFI 90 OPEN
communication highway and AC power.
3. Wire AC power to the terminals at the bottom front of the
power entry panel.
NOTE: Verify that the incoming voltage is the same as the rating on
the label of TB1 on the PEP.
The recommended minimum size for power wiring is 18-AWG
copper wire with a 600-V, 75
°−
Celsius rating and thermoplas-
tic insulation. Wire with a 300-V or 150-V rating may be used
if it is accepted by local wiring codes. Wiring must be protected
by cable trays or conduit and suited for the service voltage.
CAUTION
Do not plug modules or peripherals such as an optical disk
drive or printer into the OIS with power applied. A current
surge or voltage spike could damage sensitive components on
the unit.
