2.13 Installing the Optional Power
Supply
The optional internal power supply provides 6VDC
power for the
iQUBE from 115 or 230 VAC power
sources. It is required for iQUBE configurations that
include the Ethernet option or that consist of more
than two
iQUBE units. Fiber-optic configurations can
use the internal power supply to provide electrical
isolation from the indicator.
Figure 2-15. Optional
iQUBE
6V Power Supply
NOTE
: When using DC source that is between 8 - 16
volts, remove jumper JP1, located on the back side of
the core module. See Figure 2-2 on page 4.
2.14 Installing Option Cards
General procedures for iQUBE option cards are
described below:
Option cards are not hot-pluggable.
Disconnect power to the
iQUBE
before
installing option cards.
2.14.1 Digital-to-Analog (DAC) Conversion Cards
Two DAC cards are available for both the iQUBE and
the remote fiber-optic module:
• PN 77146, 0–30 mV DAC
• PN 77797, 4–20 mA DAC
For DAC cards to be installed in either the iQUBE or
the remote fiber-optic module, orient the DAC card so
that, when installed, its edge is aligned with the edge
of the core module (
iQUBE ) or the fiber-optic
interface board (remote fiber-optic module).
Carefully align the DAC card connector with the
board connector (J4 on the core module, J5 on the
remote fiber-optic interface board). Press down to seat
the DAC in the board connector.
See Figure 2-2 on page 4 for core module location;
see Figure 2-10 on page 12 for remote fiber-optic
interface location.
2.14.2 iQUBE Internal Fiber-Optic Option
To install the internal iQUBE fiber-optic interface
card, carefully align the option card connector with
connector J6 on the connector board (see Figure 2-2
on page 4). Press down to seat the option card in the
connector.
Figure 2-16.

2.14.3 iQUBE Internal Ethernet Option
To install the internal iQUBE Ethernet cards, carefully
align the option card connector with connector J6 on
the connector board (see Figure 2-2 on page 4). Press
down to seat the option card in the connector.
NOTE:
The optional internal iQUBE power supply is
required for configurations that include the Ethernet
option.
