2.2 Site Preparation and Prerequisites
Install ASM-20 within 1.5m (5 ft) of a grounded, easily accessible AC outlet.
The outlet should be capable of furnishing 115 VAC or 230 VAC (depending
on rated voltage of unit).
For DC units, the DC supply must be adequately isolated from the mains
supply. To prevent a fire hazard, the line supply lead should be fused or
current limited.
Allow at least 90 cm (36 in) of frontal clearance for operating and
maintenance accessibility. Ensure that there is at least 10 cm (4 in) clearance
at the rear of the unit for signal lines and interface cables.
