Illustration 23.1 BG4 mains supply connection 3 x 230 V (YukonDrive®-1041) or 3 x 400 V (YukonDrive®-1042) depending on
device design
Illustration 23.2 BG4 mains supply connection 1 x 230 V
Note:
Before commissioning, the value of the connected mains voltage must be set on the drive controller (factory setting
= 3 x 230 V AC /3 x 400 V AC).
3.7.3 Mains supply connection, BG4
Procedure:
Step
Action
Comment
1.
Specify the cable cross-section dependent on the maximum cur-
rent and ambient temperature.
Cable cross-section according to local regulations and
conditions.
2.
Wire the drive controller with the mains filter *), max. cable length
0.3 m (with non-shielded cable)!
3.
Wire the line reactor*) (if installed).
Reduces the voltage distortions (THD) in the system and pro-
longs the life of the drive controller.
4.
Install a K1 circuit breaker (power circuit breaker, contactor, etc.).
Do not switch on the power!
5.
Use mains fuses (duty class gG) to isolate all poles of the drive
controller from the mains supply.
For compliance with equipment safety requirements laid down
in EN 61800-5-1

Danger from electrical tension!
Danger to life! Never wire or disconnect electrical connections while they are live. Always disconnect the power
before working on the device. Dangerously high voltages of ≥ 50 V may still be present 10 minutes after the power is
cut (capacitor charging). So always check that the power has been cut!
