(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.
