Updates in Chapter 2– Commissioning the Supply Section with DSU
Checks with No

Air Circuit Breaker, Relays, Switches
General rule
Ensure the selectivity condition is fulfilled i.e. the breaker
trips at a lower current than the protection device of the
supplying network, and that the limit is high enough not to
cause unnecessary trips during the intermediate DC circuit
load peak at start.
Long term current limit
Rule of thumb: Set to the rated AC current of the DSU
module.
Peak current limit
Rule of thumb: Set to a value 3 - 4 times the rated AC
current of the DSU module.
Connecting Voltage to
Diode Supply Unit
If the drive is equipped with a Braking Section, the following warning applies.
WARNING! Before switching on power, make sure that sufficient inverter power is
connected to the intermediate circuit. Rules of thumb:
1. The sum power of the connected inverters must be at least 30% of the sum power
of all inverters.
2. The sum power of the connected inverters must be at least 30% of the rated power
of the braking section (P
If the conditions above are not fulfilled, the DC fuses of the connected inverter(s) may
blow or the braking chopper may be damaged.
