Installing Cables
• Prepare cables away from the cabinets to prevent scraps from falling inside. Cable scraps may 
ignite and cause personal injury or device damage.
• After cables have been installed, clean the cabinets in a timely manner. Keep the cabinets and 
surrounding environment clean and tidy.
• You need to prepare terminals onsite. The stripped length of the copper wire should be the 
same as that of the part of the terminal that covers the conductor.
The cabling route 
is for reference 
only. Connect 
cables based on 
site requirements.
