(2) Resistor unit
<GRZG type>
•
The maximum temperature rise of the brake resistors is approximately
200deg or more. For wiring, therefore, use heat-resistant wires (such as
fiber-glass braided wires) or cover the wires with silicone tube. Also perform
wiring so that the wires do not make contact with the resistors.
Also, separate a component, which is low in heat-resistant property, at least
15 to 20cm from the resistors.

Separate a component,
which is low in heat-
resistant property,
15cm to 20cm or more. *
* When it is inevitable to place a component, which is low in the heat-resisting property, in
the vicinity of the resistors, mount a temperature sensor to the component with low heat-
resisting property and make up a sequence which shuts off power of the inverter input side
by the temperature sensor signal. For the temparature sensor, contact the manufacturer.
