Enclosure surface mounting
Remove the front cover and wiring cover to fix the inverter to the surface.
5 Electrical installation
The FR-D700 series is a highly reliable product, but incorrect peripheral circuit
making or operation/handling method may shorten the product life or dam-
age the product.
Before starting operation, always recheck the following items.
● Use crimping terminals with insulation sleeve to wire the power supply and
motor.
● Application of power to the output terminals (U, V, W) of the inverter will
damage the inverter. Never perform such wiring.
● After wiring, wire offcuts must not be left in the inverter.
Wire offcuts can cause an alarm, failure or malfunction. Always keep the
inverter clean. When drilling mounting holes in a control box etc., take care
not to allow chips and other foreign matter to enter the inverter.
● Use cables of the size to make a voltage drop 2 % maximum.
If the wiring distance is long between the inverter and motor, a main circuit
cable voltage drop will cause the motor torque to decrease especially at
the output of a low frequency.
● The overall wiring length should be 500 m maximum.
Especially for long distance wiring, the fast-response current limit function
may be reduced or the equipment connected to the inverter output side
may malfunction or become faulty under the influence of a charging cur-
rent due to the stray capacity of the wiring. Therefore, note the overall wir-
ing length.
● Electromagnetic Compatibility
Operation of the frequency inverter can cause electromagnetic interfer-
ence in the input and output that can be propagated by cable (via the
power input lines), by wireless radiation to nearby equipment (e.g. AM
radios) or via data and signal lines. Install an optional filter if present to
reduce air propagated interference on the input side of the inverter. Use AC
or DC reactors to reduce line propagated noise (harmonics). Use shielded
motor power lines to reduce output noise.
For EMC correct installation refer to the Manual for Frequency Inverters and
EMC.
● Do not install a power factor correction capacitor, varistor or arrester on the
inverter output side. This will cause the inverter to trip or the capacitor,
varistor, or arrester to be damaged. If any of the above devices is installed,
immediately remove it.
● Before starting wiring or other work after the inverter is operated, wait for
at least 10 minutes after the power supply has been switched off, and
check that there are no residual voltage using a tester or the like. The
capacitor is charged with high voltage for some time after power off and it
is dangerous.

P
DANGER
The bus capacitor discharge time is 10 minutes. Before starting wiring or
inspection, switch power off, wait for more than 10 minutes, and check for
residual voltage between terminal + and – with a meter etc., to avoid a
hazard of electrical shock.
E
CAUTION
● Install the inverter on a strong surface securely and vertically with
bolts.
● Leave enough clearances and take cooling measures.
● Avoid places where the inverter is subjected to direct sunlight, high
temperature and high humidity.
● Install the inverter on a non-combustible surface.

NOTES
● When encasing multiple inverters, install them in parallel and leave clear-
ance as a cooling measure.
● When using the inverters at the ambient temperature of 40 °C or less, the in-
verters can be installed closely attached (0 cm clearance). When ambient
temperature exceeds 40 °C, clearances between the inverter should be 1 cm
or more (5 cm or more for the FR-D740-120 or more).
● Install the inverter vertically.
