3 Connect the frame ground. See Section 2.3 on page 50.

6 See Chapter 5 on page 69 for instructions on making power connections and turning on

2.2 Installation Scenarios
The IES-1248 can be placed on a desktop or rack-mounted on a standard EIA rack. Use the
rubber feet in a desktop installation and the brackets in a rack-mounted installation.
For proper ventilation, allow at least 4 inches (10 cm) of clearance at the front and 3.4 inches
(8 cm) at the back of the IES-1248. This is especially important for enclosed rack installations.
2.2.1 Desktop Installation Procedure
1 Make sure the IES-1248 is clean and dry.
2 Set the IES-1248 on a smooth, level surface strong enough to support the weight of the
IES-1248 and the connected cables. Make sure there is a power outlet nearby.
3 Make sure there is enough clearance around the IES-1248 to allow air circulation and the
attachment of cables and the power cord.
4 Remove the adhesive backing from the rubber feet.
