3. Terminals
Figures 1 and 2
show the connection terminals; the connections must be made using cables having a
minimum diameter:
•
•
•
•
1,5 mm²
for power cables on terminals from 1 to 22
•
•
•
•
0,5 mm²
for signal cables on terminals from 23 to 32
4. DER1 connections
The DER1 regulator has 3 differential inputs, with 2 selectable scales for each of them (see fig. 1):
•
scale "H" for voltages between 75V and 150V
•
scale "F" for voltages between 150V and 300V
4.1 Connections based on main alternator voltage
Based on the machine connections, and the desired voltage
(1)
you can use the three phase or single
phase sensing used in one range or the other. Table 4 summarises the connections for the most common
voltages.
