basic maintenance procedures.

POINTS OF CAUTION

 

 HOT INSERTION/REMOVAL OF MODULES

• 

Removing or replacing modules does not affect other mod-
ules on the same backplane.  It is possible to replace them 
without removing the power supply.  However, replacing 
multiple modules at once may greatly change line voltage 
levels.  We recommend that you replace them one by one.

 

 ENVIRONMENT

When heavy dust or metal particles are present in the 
air, install the unit inside proper housing with sufficient 
ventilation.

cable, high frequency line, etc.).

• 

Do not bind these cables together with those in which 
noises are present.  Do not install them in the same duct.

 

 AND ....
