Installing the Instrument
Do not block the air intake at the sides of the instrument or the exhaust at the rear of
the instrument.
You cannot use standard support rails for rack mounting your instrument as they
would block the airflow needed for cooling.
Tools required: Phillips driver, T22 Torx driver, T10 Torx driver.
1. Install eight clip-nuts on the rack frame where your instrument will be located. As shown in the
illustration, install three on each front corner; and one on each rear corner.
2. Separate the pieces of each slide rail pair and install the stationary part of each slide to the two
clip nuts on the sides of the instrument rack using the four fixed slide rail screws provided.
3. Install the movable part of each slide to the sides of the instrument using the four movable slide
rail screws provided. Use location (3a) for the 1 kW units; location (3b) for the 2 kW units, and loc-
ation (3c) for the power dissipator unit.
4. Install the front panel ears to the instrument using the six front ear screws provided.
5. Slide the instrument into the rack.
6. Attach the front ears to the instrument rack using the four front dress screws provided.
