■ No fuse breaker (NFB) and Leakage Circuit
Breaker
‧ Please refer to table 3 for choosing NFB of
appropriate current.
‧ Do not use NFB to control the start/stop of the
inverter.
‧ If a leakage circuit breaker is added for leakage
protection, its current sensitivity shall be more
than 200mA and action time more than 0.1 (V-
TYPE), so as to avoid high-frequency
malfunction.
■ Electromagnetic contactor
‧ It can not add the electromagnetic contactor for
general use. However, for the application
requiring external sequence control or
automatic restart function after power cut, an
electromagnetic contactor is required.
‧ Please avoid using electromagnetic contactor
for the start/stop control of the inverter as
possible.
■ AC reactor
‧ In case of further improving the power factor or
suppress the external surge, an AC reactor can
be additionally equipped.
■ Fast acting fuse
‧ To protect interface devices, it is necessary to
add a fast acting fuse (fuse specification will be
referred to Section 6.6)
■ Input Noise filter
‧ A510 is matched with TECO special filter,
meeting the EN 55011 class A criterion.
‧ The selection of input noise filter can be
referred to Section 6.4)
■ Inverter
‧ Terminal R,S,T at input side have no phase
sequence requirement, thus they can be
arbitrarily exchanged.
‧ Terminal E must be well grounded.
