2.2 Install the Inverter
Transportation
• The inverter is made of plastics component. When
carrying the inverter, handle it carefully to prevent
damage to the parts.
• Do not carry the inverter by holding the front or
terminal block cover. Doing so may cause the
inverter to fall.
• Do not install and operate the inverter if it is
damaged or its parts are missing.
Ambient temperature
• Avoid installing the inverter in a place where the
ambient temperature goes above or below the
allowable range defined by the standard inverter
specification.
Ambient temperature:
ND rated : -10 to 50°C
LD rated : -10 to 45°C
VLD rated*1) : -10 to 40°C
*1) SH1-03410-H(SH1-1600H)～SH1-06600-H(SH1-3150H)
support only normal duty(ND)and low duty (ND).
• Keep sufficient space around the inverter.
Measure the temperature in a position about 5 cm
distant from the bottom-center point of the
inverter, and check that the measured
temperature is within the allowable range.
Operating the inverter at a temperature outside
this range will shorten the inverter life (especially
the electrolytic capacitor life), resulting in damage
to the inverter.
Do not install on a high temperature, high
humidity or easily condensation area
• Avoid installing the inverter in a place where the
relative humidity goes above or below the range
(20% to 90% RH), as defined by the standard
inverter specification. Avoid a place where the
inverter is subject to condensation.
• Condensation inside the inverter will result in
short circuits, which may cause damage to the
inverter. Also avoid places where the inverter is
exposed to direct sunlight.
Install inverter on nonflammable
(e.g. metal) surface.
• The inverter will reach a high temperature (up to
about 150°C) during operation. Install the inverter
on a vertical wall surface made of nonflammable
material (e.g., metal) to avoid the risk of fire.
• In particular, keep sufficient distance between the
inverter and other heat sources (e.g., braking
resistors and reactors) if they are installed in the
vicinity.
• Keep enough clearance
between the inverter and the
above and below wiring ducts
to prevent cooling air
ventilation from obstructing.
