30. The customer's house has a single-phase 25A line. How many A stations are recommended for customers?
Answer: If this 25A line is only used by a charger, then 21-23A is recommended. If there are other devices used on this line, calculate it.
The maximum power of other equipment, use 220v * 25A, get the maximum power of the line, cut off the maximum power of other equipment, divide the remaining power by 220,
We can get the amperage recommended for him.
31. Our wall mount has ground protection, so do we still need earth rod (ground rod, ground electrode) during installation?
Answer: The ground rod is a galvanized iron rod at least 2 meters long. In the case of ground protection, no earth rod is required.
32. A Norwegian customer bought a 16A-32A switchable wall mount. The home is TN-400V. When connecting, one of the phase and neutral wires was connected (he said
(Equivalent to 230V) When switching to 32A, the charging can only reach up to 15.8A. The home circuit and car are determined to be 32A. Ask what is the reason
To?
A: There are many possible reasons, such as:
① The guest car battery only accepts MAX16A, so even if our WB is adjusted to 32A, it can only pass 16A current;
② When the car battery is almost full, it will become smaller; this is normal; when the car battery is exhausted, charging is the fastest, and WB
Power charging
③ It is also possible that our workers connected the wrong resistor; if it is MODE C, you can use a multimeter to measure the electricity between the PE and PP plugs.
Resistance value, if it is 220 ohms, then the connection is normal, and we are not responsible; if it is 680 ohms, it means that we have connected the wrong resistance; such errors are generally
Appears in the case of a small number of orders, because it cannot be put on the production line, and can only be done manually by an individual, there is a certain probability of error.
33. Can our single-phase wall mount be installed in three-phase power (L2, L3 need not be connected)?
Answer: Of course. L1, L2, L3 Whichever he picks, N, PE pick up normally.
34. The guest wants to customize the manual by himself, and wants to briefly describe the reason why the display screen shows the fault code; can these be informed?
CP Error cannot detect the handshake signal
