This chapter describes the configuration, location and space when mounting the
VS-626M5 and the VS-656MR5.
Choosing A Location To Mount The Converter
To ensure proper performance and long operating life, follow the recom-
mendations below when choosing a location for installing the VS-626M5
and the VS-656MR5. Make sure the inverter and the converter are pro-
tected from the following conditions:
• Extreme cold and heat.
Use only within ambient temperature range: 0
°
C to +55
°
C (32
°
F to
131
°
F)
• Rain, moisture.
• Oil sprays, splashes
• Salt spray.
• Direct sunlight. (Avoid using outdoors.)
• Corrosive gases or liquids.
• Dust or metallic particles in the air.
• Physical shock, vibration.
• Magnetic noise. (Example: welding machines, power devices, etc.)
• High humidity.
• Radioactive materials.
• Combustibles: thinners, solvents, etc.
• Lift the mounting base. When moving the unit, never lift by the front cover, to avoid
damaging the unit.
• Mount the inverter and the converter on a nonflammable material (i.e., metal). Failure
to observe this caution can result in a fire.
• Install a fan or other cooling device to keep the ambient temperature of inverter and
converter below 55
°
C (131
°
F) and the intake air temperature to heat sink below 45
°
C
(113
°
F). Overheating may cause a fire or damage to the unit.
• Build an external emergency stop circuit that immediately stops operation and shuts
down power in an emergency. Failure to observe this caution may result in personal
injury.
