3.1 Mechanical Installation

 

3.1.1 Installation Environment 

1.  Ensure  that  the  ambient  temperature  and  humidity  meet  the  requirements  in  the 
following  table.  Install  the  braking  unit  in  an  environment  free  from  vibration  and  direct 
sunlight. 

2.  Install  the  braking  unit  and  external  braking  resistor  on  the  surface  of  incombustible 
objects with sufficient room for heat dissipation. 

3.  Ensure  that  the  installation  environment  is  free  from  corrosive,  combustible,  and 
explosive gas. 

4. Ensure that installation environment is free from dust and metal powder.
