Figure 2–2: Attaching the Rails to the Rack
CAUTION: Make sure to install the rack rails with the shelf at the top of the rail. If you install the
rail upside down, the rail blocks the encoder air vents, which can result in overheating the encoder.
Mounting the Encoder
CAUTION: Rack mount the encoder using the screws that came with your Harmonic rail kit. If you
did not purchase a Harmonic rail kit, use a rack-mount screw with a head no larger than 0.4 inches in
diameter and 0.14 inches in height to avoid damaging the front panel of the encoder. (Some encoders
may come with a peel-away sticker that advises on the correct screw size.) Using only the bottom two
screw holes will be sufficient.
To mount the encoder in a rack:
1. Using both hands, grasp the right corner of the front bezel and slowly pull to detach the
hinge on the left side of the encoder and expose the mount holes. See
Figure 2–3 .
DANGER: The front panel display on the encoder is susceptible to electrostatic discharge (ESD) when
the bezel is removed. Wear the appropriate ESD protection when the bezel is removed.
2. Gently slide the encoder to rest on the rack rails.
3. Push the encoder back until the rack-mount holes in the front of the encoder line up with
the rack posts.
4. Insert four screws through the mount holes in the front of the encoder to the
corresponding holes on the rack posts.
5. Tighten the screws with a screwdriver.
