Design
thermal relay to detect resistor overheating. When using a Braking Resistor Unit,
use an error output contact. Otherwise, a fire may occur.

Note Do not use a Resistor whose resistance is below the minimum connected resis-
tance. Otherwise, the Inverter will be damaged.
D Installing a Noise Filter on the Power Supply Side
Install a noise filter to eliminate noise transmitted between the power line and the
Inverter.

Note Use a noise filter designed for Inverters. A general-purpose noise filter will be less
effective and may not reduce noise.
