TO BE NON-HAZARDOU
Each expansion rack can support up to 3 Graphite modules, and up to
4 racks can be bolted together, to provide up to 12 Graphite modules per
expansion rack system. The expansion racks connect and communicate
via proprietary USB connection to the various Graphite host devices, via
standard USB A/B cable. The GEXRACK1 USB base rack provides the
interface to the Graphite host, and up to 3 GEXRACK2 3-Port expansion
racks can be attached to the USB base rack. The backplane connection
between expansion racks provides power and communications for the
downstream racks and modules. The GEXRACK1 also offers a filtered
power supply for both the rack and the Graphite host device which can
be used when installing in electrically noisy environments.
The Graphite host devices, equipped with serial ports as well as
Ethernet port(s), allows the system to share data with PCs, PLCs, and
SCADA systems.
The expansion racks snap easily onto standard top hat (T) profile DIN
rail, or can be bolted directly to the panel in high vibration environments.

EMC INSTALLATION GUIDELINES
Although Red Lion Controls products are designed with a high degree
of immunity to Electromagnetic Interference (EMI), proper installation and
wiring methods must be followed to ensure compatibility in each
application. The type of the electrical noise, source or coupling method
into a unit may be different for various installations. Cable length, routing,
and shield termination are very important and can mean the difference
between a successful or troublesome installation. Listed are some EMI
guidelines for a successful installation in an industrial environment.
1. A unit should be mounted in a metal enclosure, which is properly
connected to protective earth.
2. Use shielded cables for all Signal and Control inputs. The shield
connection should be made as short as possible. The connection point
for the shield depends somewhat upon the application. Listed below
are the recommended methods of connecting the shield, in order of
their effectiveness.
a. Connect the shield to earth ground (protective earth) at one end
where the unit is mounted.
b. Connect the shield to earth ground at both ends of the cable, usually
when the noise source frequency is over 1 MHz.
3. Never run Signal or Control cables in the same conduit or raceway with
AC power lines, conductors, feeding motors, solenoids, SCR controls,
and heaters, etc. The cables should be run through metal conduit that
is properly grounded. This is especially useful in applications where
cable runs are long and portable two-way radios are used in close
proximity or if the installation is near a commercial radio transmitter.
Also, Signal or Control cables within an enclosure should be routed as
far away as possible from contactors, control relays, transformers, and
other noisy components.
4. Long cable runs are more susceptible to EMI pickup than short cable runs.
5. In extremely high EMI environments, the use of external EMI
suppression devices such as Ferrite Suppression Cores for signal and
control cables is effective. The following EMI suppression devices (or
equivalent) are recommended:
Fair-Rite part number 0443167251 (Red Lion Controls #FCOR0000)
Line Filters for input power cables:
Schaffner # FN2010-1/07 (Red Lion Controls #LFIL0000)
6. To protect relay contacts that control inductive loads and to minimize
radiated and conducted noise (EMI), some type of contact protection
network is normally installed across the load, the contacts or both. The
most effective location is across the load.
a. Using a snubber, which is a resistor-capacitor (RC) network or metal
oxide varistor (MOV) across an AC inductive load is very effective at
reducing EMI and increasing relay contact life.
b. If a DC inductive load (such as a DC relay coil) is controlled by a
transistor switch, care must be taken not to exceed the breakdown
voltage of the transistor when the load is switched. One of the most
effective ways is to place a diode across the inductive load. Most
Red Lion products with solid state outputs have internal zener diode
protection. However external diode protection at the load is always a
good design practice to limit EMI. Although the use of a snubber or
varistor could be used.
Red Lion part numbers: Snubber: SNUB0000
Varistor: ILS11500 or ILS23000
7. Care should be taken when connecting input and output devices to the
instrument. When a separate input and output common is provided,
they should not be mixed. Therefore a sensor common should NOT be
connected to an output common. This would cause EMI on the
sensitive input common, which could affect the instrument’s operation.

Safety and CE issues as they relate to Red Lion products.

(46.6)
It is recommended that the expansion rack be DIN rail mounted only in
low vibration environments. Refer to the Specifications section for details.
1. Using a screwdriver, push in and fully rotate the Cam counterclockwise to push the DIN Clip downward against spring pressure
locking it open
2. Place the base on the DIN rail. Place each additional base, and slide
them together until the connectors engage. Then fasten the bases
together with the two captive screws, located at each junction.
3. Using a screwdriver, push in and rotate the Cam 90 degrees clockwise
to release the DIN clip to engage the DIN rail
4. Rotate the Cam an additional 90 degrees clockwise to lock the DIN clip
in the closed position. The CAM must be in fully locked position to
meet the vibration specification listed.

MODULE INSTALLATION
CONNECTING TO EARTH GROUND The physical order of all installed modules must match the modules
order in Crimson. Torque screws to 6.0 pound-force inch [96 ounce-force
inch] (0.68 Nm).
The third pin of the power connector is chassis ground for the unit.
Your unit should be connected to earth ground.
The chassis ground is not connected to signal common of the unit.
Maintaining isolation between earth ground and signal common is not
required to operate your unit. But, other equipment connected to this unit
may require isolation between signal common and earth ground. To
maintain isolation between signal common and earth ground, care must
be taken when connections are made to the unit. For example, a power
supply with isolation between its signal common and earth ground must
be used. Also, plugging in a USB cable may connect signal common and
earth ground.1
1 USB’s shield may be connected to earth ground at the host. USB’s
shield in turn may also be connected to signal common.
WARNING: Disconnect all power
to the unit before installing or
removing modules.
POWER SUPPLY REQUIREMENTS
The Graphite expansion rack requires a 10-30 VDC power supply.
Your unit may draw considerably less than the maximum rated power
depending upon the modules being used.
To ensure you do not exceed the capacity of your Graphite expansion
rack power supply, calculate the total power consumption required for all
of your planned modules. Each module’s maximum power consumption
is listed in the Specifications of their respective Product Bulletin. The total
power available for modules is listed in the Graphite Expansion Rack
Specifications.
It is very important that the power supply is mounted correctly if the unit
is to operate reliably. Please take care to observe the following points:
– Voltage range stated is at the power connector, not at the power
source.
– Peak efficiency occurs at the low side of the voltage range
(approximately 12 V), recommended for high temperature applications.
– The GEXRACK1 contains two built-in power supply line filters: one
for the expansion rack system, and one for the Graphite host. The
power supply is wired to the POWER INPUT CONNECTOR of the
GEXRACK1, then the HOST POWER OUTPUT of the GEXRACK1
is wired to the Graphite host power input. This setup provides the
best EMC performance.
– The power supply must be mounted close to the unit expansion rack,
with usually not more than 6 feet (1.8 m) of cable between the
supply and the expansion rack. Ideally, the shortest length possible
should be used.
– Separate power supplies can be used for the Graphite host and the
expansion rack system, but EMC performance will be reduced. Both
the Graphite host and the expansion rack system must be properly
connected to protective earth, as per the “CONNECTING TO
EARTH GROUND” section.
– The wire used to connect the Graphite host’s power supply should
be at least 22-gage wire, suitably rated for the temperatures of the
environment to which it is being installed. If a longer cable run is
used, a heavier gage wire should be used. The routing of the cable
should be kept away from large contactors, inverters, and other
devices which may generate significant electrical noise.
– A power supply with an NEC Class 2 or Limited Power Source (LPS)
and SELV rating is to be used. This type of power supply provides
isolation to accessible circuits from hazardous voltage levels
generated by a mains power supply due to single faults. SELV is an
acronym for “safety extra- low voltage.” Safety extra-low voltage
circuits shall exhibit voltages safe to touch both under normal
operating conditions and after a single fault, such as a breakdown of
a layer of basic insulation or after the failure of a single component
has occurred. A suitable disconnect device shall be provided by the
end user.
