The operating humidity is 15 to 95%, non-condensing.
The maximum operating altitude is 2000 m.
The instruments are designed for pollution degree 2.
The instrument has a cooling fan mounted internally.
Mount or position your instrument upright and horizontally, as shown
in Figure 4 so that air can circulate through it freely.
Operating Position
When operating the instrument choose a location that provides at least
75 mm (3 inches) of clearance at the rear, and at least 25 mm (1 inch)
of clearance at each side. Failure to provide adequate air clearance may
result in excessive internal temperature, reducing instrument
reliability. The instrument should not be operated when resting on its
rear or side panels.
