6.1 Safety Precaution
DANGER
· All operations, cables and parts specification during the electrical
connection shall be in compliance with local laws and regulations.
· Disconnect the upstream switch before electrical connection. Do not work
with power on. Otherwise, an electric shock may occur.
· Tie the same type cables together, and place them separately from cables of
different types. Do not place the cables entangled or crossed.
· If the cable bears too much tension, the connection may be poor. Reserve a
certain length of the cable before connecting it to the charger cable port.
· When crimping the terminals, ensure that the conductor part of the cable is
in full contact with the terminals. Do not crimp the cable jacket with the
terminal. Otherwise the charger may not operate, or its terminal block getting
damaged due to heating and other phenomena because of unreliable connection
after the operation.
WARNING
· Connect the AC input cables to the corresponding terminals such as “L1”,
“L2”, “L3”, “N” and “PE” ports correctly. Otherwise it will cause damage to
the charger.
· Ensure that the whole cable cores are inserted into the terminal holes. No
part of the cable core can be exposed.
· Ensure that the cables are connected securely. Otherwise it will cause
damage to the charger due to overheat during its operation.
NOTICE
· Wear personal protective equipment like safety shoes, safety gloves, and
insulating gloves during electrical connections.
· All electrical connections should be performed by qualified professionals. ·
Cable colors in this document are for reference only. The cable specifications
shall meet local
