3.3.3 Seawater (Salt Spray Damage)
Due to the salty air, a large volume of sea salt particles are suspended in the air near coastal areas. If
these sea salt particles enter computers, they may cause insulation to fail and parts to corrode or degrade
due to moisture and chemical condensation. Therefore, computers must be installed far from coastal areas.
The installation criteria for preventing salt spray damage from sea salt particles is as follows.
Criteria: The installation is not at sea nor within 0.5 km from the seashore. (An exception is an installation
using air conditioners that do not take in outside air.)
3.4 Distribution Panel Cut-Off Characteristics
The characteristics of breakers in the customer’s distribution panel must be considered so that the FX700
main unit can run optimally. Use suitable breakers according to " Table 3.3 Distribution Panel Breaker
Characteristics ."
Use a long-time-delay type breaker whose cut-off characteristics correspond to phase D shown in " Figure
3.1 Distribution Panel Breaker Characteristics " (IEC898 or DIN0641 Part II). Alternatively, use a slower
breaker.
