4.2. Requirements
If the environmental conditions differ from those specified in section “Technical
data” on page 81, as to temperature and humidity, or if the atmosphere around the
machine terminal contains chemically active gases or dust, the terminal should be
visually inspected in association with the secondary testing. The visual inspection
should focus on:
• Signs of mechanical damage to the terminal case and terminals
• Dust inside the terminal cover or case; remove carefully with compressed air
• Signs of corrosion on the cable terminals, on or inside the terminal case
For information about the maintenance of machine terminals, refer to Chapter 6.

Machine terminals are measuring instruments and should be handled
with care and protected against moisture and mechanical stress,
especially during transport.
