AC POWER WIRING GUIDELINES
IIOIC422 AC power input connects to a terminal block on the
power entry panel. The power entry panel location and part
number will vary according the IIOIC42 model selected. The
IIOIC421 (tabletop model) does not use the power entry panel.
It has a rear connector panel with an IEC style AC input on the
keyboard interface assembly. Refer to the following sections
under
for detailed AC power wiring con-
nection procedures. The operator interface console can oper-
ate from 120/240 VAC, 50/60 hertz. The power entry panel
provides line filtering, transient suppression and a 20-amp cir-
cuit breaker.
Setting up the IIOIC42 console for 240 VAC requires no
changes. The power supply is autosensing. Refer to
for more power supply information. The color monitor is
autosensing and needs no changes for 240-VAC operation.
Monitors by other vendors may require changes. The CPU is
also autosensing and needs no change for 240-VAC operation.
The recommended minimum size for power wiring is 14 AWG
copper wire with a 600 volt, 75-degrees Celsius (167-degrees
Fahrenheit) rating and thermoplastic insulation. Wire with a
300-volt or 150-volt 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.
Power wiring to the OIC console must include a third-wire
grounding conductor. This grounding conductor must not be a
smaller gauge than the power wiring and must be either bare,
green colored or green/yellow colored if insulated. The ground-
ing conductor must be terminated at the system safety ground
connection on the front of the power entry panel.
CAUTION
Make sure that all voltage labels and voltage switch settings on
the peripheral devices, power supply and power entry panel
show the correct operating voltage. Equipment damage may
result if the incorrect voltage is connected. Make sure the con-
sole main power circuit breaker is off before changing operat-
ing voltage setting or equipment damage may result.
ATTENTION
Assurez-vous que toutes les indications de tension et tous les
réglages de tension sur les périphériques, le bloc d´alimenta-
tion et le panneau d´entrée des alimentations correspondent
bien à la tension de service. Une tension incorrecte risque
d´endommager l´equipment. Assures-vous que le disjoncteur
d´alimentation principal de la console est étient avant de modi-
fier les réglages de tension de service afin d´éviter d´endom-
mager l´équipment.
