After installation has been completed, see Chapter 3, Operation for operating
information and system checkout to assure normal operation.
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.
