(1) To improve the unit's resistance to signal interference, install
modules for low-voltage signals toward the left of the unit, and
modules for power signals toward the right. Also, separate the
wires of each,
(2> Allow at least
too
mm (4 in) clearance between the units and
between other control equipment to allow access for
maintenance and ventilation,
(3) When installing the unit near high-voltage or high-power
equipment, leave at least 200 mm (8 in) clearance, or shield the
unit with a steel plate.
