(14 to 131°F) with relative humidity within 30 to 90% RH
in order to ensure adequate life span and operation.
• Be sure that the ventilation slits are not covered with ca-
bles, etc.
■ WIRING
• Make sure for safety that only qualified personnel per-
form the wiring.
• Do not install cables close to noise sources (high frequen-
cy line, etc.).
• Do not bind these cables together with those in which
noises are present. Do not install them in the same duct.
