Three or more layers of insulation are required.
Method 1
Insulation tape
Insulation tape
Method 2
CAUTION
• Make sure that the connection parts are not exposed
to outside.
• Be sure to use insulation tape and a contraction tube
made of approved reinforced insulating materials
that have the same level of withstand voltage with
the power cable. (Comply with the local regulations on
extensions.)
WARNING
• In case of extending the electric wire, please DO NOT
use a round-shaped Pressing socket.
– Incomplete wire connections can cause electric
shock or a fire.
