Operating Environment - Fuji Electric ALPHA7 User Manual

CHAPTER 1 INSTALLATION
 If storing for 1 year or longer
The properties of electrolytic capacitors will deteriorate if the power is not turned ON for a long period of
1
time, and therefore the product should be connected to a power supply once a year, and turned ON for
30 to 60 minutes. Do not wire or run the output side (secondary side).

1.2.2 Operating Environment

Operate the servo amplifier in the following environment. The servo amplifier is neither dust proof nor
water proof.
Ambient temperature -10 [°C] to +55 [°C] (no freezing allowed)
Ambient humidity
Observe the following when operating.
 Install indoors at a place free from rainwater and direct sunshine.
 Do not operate in corrosive atmosphere including hydrogen sulfides, sulfurous acid, chlorine,
ammonia, sulfur, chlorine-based gases, acids, alkalis or salts or near flammable gases or matters.
 Install in a well ventilated environment with less vapor, oil and water content.
 Install at a place with less vibration.
 Use in locations with oil, water vapor or corrosive gas, or in dusty locations
 Use in intense electric fields or in ferromagnetic fields
 Use in the same control panel as that used for high-voltage (2 kV) equipment
 Use with the same power supply as devices which generate a lot of noise
 Other surrounding environments in which use prohibited
(i) Locations with powerful electromagnetic waves
(ii) Vacuum
(iii) In explosive atmosphere
(iv) Under acceleration, vibration conditions
