•Power — The device is installed within 1.5 m (5 feet) of a grounded, easily accessible outlet 220/110 VAC, 50/60 Hz. If the device has two power supplies, the site should have two power outlets with different power feeders.

•General — Ensure that the power supply is correctly installed.

•Clearance — There is adequate frontal clearance for operator access. Allow clearance for cabling, power connections, and ventilation.

•Cabling — Cabling is routed to avoid sources of electrical noise such as radio transmitters, broadcast amplifiers, power lines, and fluorescent lighting fixtures.

•Ambient Requirements — The ambient unit operating temperature range is 0 to 45C (32 to 113F) at a relative humidity of up to 95%, non-condensing. Verify that water or moisture cannot enter the device case.
