(2) Electrical Connection
The type of electrical connection is depends on the model code suffix.
The model code suffix is shown on the main label in front of YFGW710.
The second character following the letter A shows the type of electrical connection as below.
Character b on Suffix: Aab-cdefghjkm The type of electrical connection
2 1/2 NPT female *1
4 M20 female *2
Note *1: 1/2 NPT is realized by the conversion adapter from M20 female to 1/2NPT female.
Note *2: When the cable glands or another device are necessary, user needs to prepare them which adapt to M20 female entry.
