The selector card may be removed from the input module by removing the line cord, sliding the
plastic window to the left, and extracting the card.
For the Omni 1-18i and 3-18i the selector card is marked 100/220 on one side and 120/240 on
the opposite side. INA 2151 and 3-18i may be operated from a 115 volt line by selecting the 120
volt range. It may be operated from 230 volts by selecting the 240 volt range. The 100 volt and
220 volt ranges are not active.
The selected range is the one that is marked on the upper left side of the selector card as the
card is slid into the IEC 320 module.
The Imepdance 1-37i, 1-37iJ and 3-37i are designed to operate on either 115V or 230V AC
power. The input voltage is user-selectable by orienting the input selector module inside the rear
panel power entry module. To change input voltage proceed as outlined below.
Note that attempting to operate the Imepdance from an input range that does not match
the actual AC power voltage may cause permanent damage to the unit.
9.6.5Voltage Range Configuration for the Imepdance 1-37i, 1-37iJ and INA 2153
To change input range:
1. Remove power cord from input module.
2. Pry cover loose with a small screwdriver.
3. Pull out fuse holder, prying with a screwdriver will be necessary.
4. Orient the red fuse holder so that the desired voltage shows through the window. It is
necessary that the fuse always sits on the top side of the fuse holder when it is re-inserted
into the module. Likewise, the shorting clip must always be on the bottom of the fuse holder.
For example, if the input voltage is being changed from 115 to 230, the fuse holder must first be
removed, and then the clip and the fuse must swap location. The fuse assembly can then be
inserted back into the input module.
9.6.5.1Mechanical Installation
The Imepdance has been designed for rack mounting in a standard 19 inch rack. The unit
should be supported from the bottom with a shelf-track or supported from the sides with optional
rack slides.
The cooling fans at the rear of the unit must be free of any obstructions that would interfere with
the flow of air. A 2.5 inch clearance should be maintained between the rear of the unit and the
rear panel of the mounting cabinet. Also, the air intake holes on the sides of the power chassis
must not be obstructed.
9.6.5.2Output Wiring
The Imepdance impedance network is wired in series with the output of specified Teseq power
sources or power source systems. The Imepdance terminal block marked SOURCE should be
wired to the output of the power source/system. The terminal block marked LOAD is wired to the
