14. Notes for Power Distribution
1. A.V.R. have different installing standards according to whose capacity size and various different types of
voltage. Please accord the specification of A.V.R. ordered to select proper power distribution, in particular pay
attention to the diameter of line whether is complied with the specification or not.
2. Please pay attention to input terminal of A.V.R. needed to avoid using the same switch other equipment.
3. Power polarity judging method please referred to the next paragraph of "Power Polarity judging Method".
4. For three-phase voltage regulator system, in particular, pay attention to the problem of connecting input and
output line phase sequence.
5. For safety, when proceeding line connection, please interrupt power supply and prohibit hot line operation.
6. Please refer to electrical engineering operation rules to proceed line connection.
7. For three-phase voltage regulator system, input power is connected to one end of input power supply switch,
the output power of A.V.R. is connected to output line terminal of terminal disk. Besides, neutral line N and
grounding line G have already marked clear with labels, please accord specification to proceed line connection.
15. Power Polarity Judging Method
1.Hot Line: in respect to hot line(line to line) voltage, there are 190V 200V 208V 220v 230V 380V 400V 415V
440V 480V etc. for three-phase three lines or three phase four lines systems.
2. Neutral line: is also called water line, in respect to hot line voltage, there are 100V 110V 115V 120V 127V
132V 220V 227V etc., in inspect to grounding lint voltage about 0.2V~2.0V. For three-phase three lines system
there is no neutral line.
3. Grounding line: earth of connection point of earth bar or distributor.
4. If the voltage of difference more than 5V in between neutral line and grounding line, or there is a special
requirement for installation system, for keeping the system safety , please send for qualified electrical
technician to reinstall al good earth system.
5. For three-phase four lines system the general voltage is as follows:
110V/190V 115V/200V 120V/208V 127V/220V 132V/230V 220V/380V 230V/400V 240V 415V 254V/440V
277V/480V
6. For three-phase three lines system the general voltage is as follows:
190V 200V 208V 220V 230V 380V 440V 480V.
7. For single phase two lines systems is as follows:
100V 10V 115V 120V 127V 132V 220V 254V 227V.
8. Hot line marked method: for single phase system, marked as L, L1, L2, for three system , marked as R, S, T,
U, V, W.
9. Neutral line i.e. water line mark: single phase system and three-phase system are all marked as N.
10. grounding line marked as "G" or used the symbol "
- 18 -
