For wiring, use a G1/2 cable gland to achieve enclosure rating of IP65.
The cable gland should conform to the wire diameter of the
communication and power supply cables and should be tightened with
the specified torque. Incorrect handling of the wiring entry may allow
foreign matter to enter the SI unit, which will lead to a malfunction and
damage to the SI unit. Use the waterproof plug assembly
