
For safety consideration, install an overload relay between the braking unit and
the braking resistor. In conjunction with the magnetic contactor(MC) prior to the
drive, it can perform complete against abnormality.

The purpose of installing the thermal overload relay is to protect the braking
resistor from damage due to frequent braking, or due to braking unit keeping
operating resulted from unusual high input voltage. Under such circumstance,
just turn off the power to prevent damaging the braking resistor.
【
Note
】

Inflammable solids, gases or liquids must be avoided at the location where the
braking resistor is installed. The braking resistor has better be installed in
individual metallic box with forced air-cooling.

Connect the ground terminal to the Earth Ground. 230V followers the third
grounding construction. 460V followers the special third grounding construction.

Please install braking resistor with forced air-cooling or the equivalent when
frequent deceleration braking is performed (over 10ED%).

To prevent personal injury, do not connect/disconnect wires or regulate the
setting of the braking unit while power on. Do not touch the terminals of related
wiring and any component on PCB lest users be damaged by extreme dangerous
DC high voltage.

The ring terminals are suggested to be used for main circuit wiring. Make sure the
terminals are fastened before power on.

The cable distance between the inverter and the brake unit should be less than 2
meters. The brake unit and brake resistor should be less than 1 meter, and the
master-slave parallel control line (B1) and (B2) should be less than 30 cm.
