HD2 IP55 High-ingress Protection Series Inverter
-322
Image Name Description
Cable Accessory for signal transmission
Breaker
Device for electric shock prevention and
protection against short-to-ground that may
cause current leakage and fire. Select
residual-current circuit breakers (RCCBs)
that are applicable to inverters and can
restrict high-order harmonics, and of which
the rated sensitive current for one inverter is
larger than
30 mA.
Input reactor
Accessories used to improve the current
adjustment coefficient on the input side of the
inverter, and thus restrict high-order
harmonic
currents.
Input filter
Accessory that restricts the electromagnetic
interference generated by the inverter and
transmitted to the public grid through the
power cable. Try to install the input filter near
the input terminal side of the inverter.
or
Brake unit or brake
resistor
Accessories used to consume the
regenerative energy of the motor to reduce
the deceleration time.
inverters of HD2IP-75A-43 or lower only
need to be configured with brake resistors,
and inverters of above HD2IP-75A-43
support optional brake units.
Output filter
Accessory used to restrict interference
generated in the wiring area on the output
side of the inverter. Try to install the output
filter near the output terminal side of the
inverter.
Output reactor
Accessory used to lengthen the valid
transmission distance of the inverter, which
effectively restrict the transient high voltage
generated during the switch-on and
switch-off of the IGBT module of the inverter.
D.3 Power supply
Refer to the electrical installation.
D.4 Cables
D.4.1 Power cables
The sizes of the input power cables and motor cables must meet the local regulation.

Ensure that the voltage class of the inverter is consistent with that of the
grid.
