2.0 INSTALLATION
2.1 Installing Module
Carefully slide the module into the open slot in the chassis. Align the module with the
installation guides and ensure that the module is firmly seated against the backplane. Secure
the module by fastening the front panel thumbscrew (push in and turn clockwise to tighten)
to the chassis front.
2.2 AC Powered Chassis
To power the unit using the AC/DC adapter, connect the AC/DC adapter to the AC outlet.
Then connect the barrel plug at the end of the wire on the AC/DC adapter to the DC barrel
connector (center-positive) on the unit. Route the power cable through the provided strain
relief for additional support. Confirm that the unit has powered up properly by checking the
Power LED located on the front of the installed module. Use only the supplied AC/DC power
adapter to power the chassis.
NOTE: The 8242-x and 8243-x models use a different AD/DC power adapter than the
8240-x and 8241-x models. The DC barrel connector on the 8242-x and 8243-x is a
2.1mm center connector and supplies a nominal 48VDC. The DC barrel connector
on the 8240-x and 8241-x is a 2.5mm center connector and supplies a nominal 9VDC.
If installing with the NEBS Mounting Kit for 8242-x and 8243-x models, secure the grounding
wire to the ground lug. See Figure 2 for the location of the grounding lug.

2.3 DC Powered Chassis Site Preparation
Power source should be available within 5 ft. of the chassis. The over current protection for
connection with centralized DC shall be provided in the building installation, and shall be
a UL listed circuit breaker rated 20 Amps, and installed per the National Electrical Code,
ANSI/NFPA-70.
This equipment requires 20-60VDC/0.6Amp rated power. Appropriate overloading protection
should be provided on the DC power source outlets utilized.
WARNING: Only a DC power source that complies with
safety extra low voltage (SELV) requirements can be
connected to the DC-input power supply.
WARNING REGARDING EARTHING GROUND:
o
o
o
o
This equipment shall be connected to the DC supply system
earthing electrode conductor or to a bonding jumper from an
earthing terminal bar or bus to which the DC supply system
earthing electrode is connected.
This equipment shall be located in the same immediate area
(such as adjacent cabinets) as any other equipment that has
a connection between the earthed conductor of the same DC
supply circuit and the earthing conductor, and also the point
of earthing of the DC system. The DC system shall not be
earthed elsewhere.
The DC supply source is to be located within the same
premises as this equipment.
There shall be no switching or disconnecting devices in the
earthed circuit conductor between the DC source and the
earthing electrode conductor.
The standard operating temperature of this equipment is 0 to 50 degrees C. If installed in
a closed or multi-module rack assembly, the operating ambient temperature of the rack
must not exceed the maximum rated 50 degrees C. See specifications on page 7 for wide
temperature ranges.
Installation of the equipment should be such that the air flow in the front, back and top vents
of the chassis are not compromised or restricted.
Never use this equipment to carry any weight except its own. Never use it as a shelf to
support weight of other equipment.
2.4 DC Powered Chassis Mounting
Locate the DC circuit breaker of the external power source, and switch the circuit breaker
to the OFF position.
Prepare a power cable using a three conductor insulated wire (not supplied) with a 14 AWG
gauge minimum. Cut the power cable to the length required.
Strip approximately 3/8 of an inch of insulation from the power cable wires.
Connect the power cables to the
iConverter Chassis by fastening the stripped ends to the
DC power connector. Route the power cables through the provided strain relief for additional
support.
