 Installation 
 
 
RISK OF ELECTRIC SHOCK 
 
Terminal covers, main covers, and cover fixings must remain in place 
while the drive is energised. 
These should only ever be removed once the supply to the unit and/or 
system has been disconnected, and the residual energy in the DC link 
capacitors has been discharged. 
 
 
ESD SENSITIVE EQUIPMENT 
 
Take ESD precautions when handling the Communication Interface 
Option Cards to avoid any risk of damaging the equipment. 
 
The Communication Interface Option Cards are intended to be customer installed. 
Note: Do NOT install the Comms Option with power applied to the product, as damage may occur.
