• The Power and communication line needs to match the polarities. If it is incorrect, it will not
work.
• Turn power off before wiring. and then power it on after wiring.
• Be careful because static electricity can cause product damage
during installation.
• For the wired Power wire, Communication wire and Signal wire,
remove the coating at the end of the wire to connect and than use
the pin type (JOBN153) to connect to the terminal block
• All field supplied parts and materials and electric works must be
conform to local codes.
• Use copper wire only.
