CHAPTER 3 - INSTALLATION AND CONNECTION
-UD: negative pole of the DC link circuit is not available on
the models 1.6 A-2.6 A-4.0 A-7.0 A/200-240 V and models
1.0 A-1.6 A-2.6 A-4.0 A/380-480 V. It is used when the
inverter supplied by DC voltage (with the teUD). In
order to avoid an incorrect braking resistor connection
(mounted outside the inverter), there is a protective rubber
plug on this terminal, which must be removed if the –UD
terminal has to be used.
BR: Connection for the braking resistor.
Not available on the models 1.6A-2.6A-4.0A-7.0A/200-240 V
and on the models 1.0 A-1.6 A-2.6 A-4.0 A/380-480 V.
+UD: positive pole of the DC link circuit, not available on
the models 1.6 A-2.6 A-4.0 A-7.0 A/200-240 V and on the
models 1.0 A-1.6 A-2.6 A-4.0 A/380-480 V. It is used to
connect the braking resistor (with the BR terminal) or when
the inverter shall be supplied by with DC voltage (jointly
with the –UD terminal.
DCR: Connection for the external DC link circuit inductor
(optional). It is only available on the models 28 A and 33 A/
200-240 V and on the models 24 A and 30 A/380-480 V.
c) 22 A/200-240 V and 13-16 A/380-480 V models
b) 7.3-10-16 A/200-240 V and 2.7-4.3-6.5-10 A/380-480 V models
a) 1.6-2.6-4.0-7.0 A/200-240 V and 1.0-1.6-2.6-4.0 A/380-480 V models
