NOTE!
It is important that all the flexible braids have the same length (defined by dimension “E”), which will
depend on the panel construction.
3.2.7 Output Connections
ATTENTION!
The inverter has an electronic motor overload protection that must be set according to the motor. When
several motors are connected to the same inverter, install individual overload relays for each motor.
ATTENTION!
The motor overload protection available on the CFW-11W G2 complies with IEC609047-4-2 and
UL508C; see the information below:
„
Trip current equal to 1.25 times the motor rated current (P0401) set on the "Oriented Start-up" menu.
„
The maximum value of parameter P0398 (Motor Service Factor) is 1.15.
„
Parameters P0156, P0157 and P0158 (overload current at 100 %, 50 % and 5 % of the rated speed,
respectively) are automatically set when parameters P0401 (motor rated current) and/or P0406
(motor cooling) are set on the "Oriented Start-up" menu. If parameters P0156, P0157 and P0158
are manually set, the maximum value allowed is 1.05 x P0401.
