HARDWARE
INSTALLATION
DIN rail should be mounted horizontally so that the unit’s ventilation holes
are vertical in relation to cabinet orientation. A minimum clearance of 1 inch
(25.4 mm) should be maintained above and below the unit in order to ensure
proper thermal regulation.

POWER SUPPLY REQUIREMENTS
It is very important that the power supply is mounted correctly if the unit is
to operate reliably. Please take care to observe the following points:
– The power supply must be mounted close to the unit, with usually not more
than 6 feet (1.8 m) of cable between the supply and the master. Ideally, the
shortest length possible should be used.
– The wire used to connect the master’s power supply should be at least 22-
gage wire. If a longer cable run is used, a heavier gage wire should be
used. The routing of the cable should be kept away from large contactors,
inverters, and other devices which may generate significant electrical
noise.
– A power supply with a Class 2 or SELV rating is to be used. A Class 2 or
SELV power supply provides isolation to accessible circuits from
hazardous voltage levels generated by a mains power supply due to single
faults. SELV is an acronym for “safety extra-low voltage.” Safety extra-
low voltage circuits shall exhibit voltages safe to touch both under normal
operating conditions and after a single fault, such as a breakdown of a
layer of basic insulation or after the failure of a single component has
occurred.

power supplies.
