The standby currents for all the possible combinations of the converter are given in the following
table:
Table 4-3 Standby currents
Device Power supply Standby current (mA)
G110M FSA (0.37 ... 1.5 kW) Mains only 325
G110M FSB (2.2 ... 4.0 kW) Mains only 445
G110 FSA + Optional 24 V PSU or
External 24 V Mains + Optional 24 V PSU or External
24 V* 340
G110 FSB + Optional 24 V PSU or
External 24 V Mains + Optional 24 V PSU or External
24 V* 460
PROFIBUS / USS CM only External 24 V only* (mains supply
switched off) 235
PROFINET / AS-i CM only External 24 V only* (mains supply
switched off) 290
* The optional 24 V PSU is an orderable item which is designed specifically for use with the SINAMICS
G110M converter. The 24 V PSU is fitted to the terminal housing
Installing the 24V power supply (Page 55)
The external 24 V supply is sourced by the user and is connected to the converter through the 24 V
connections
Connection and cables (Page 67)
The maximum combined current for all digital inputs is 200 mA, the maximum combined currents for all
the digital outputs is 500 mA.
Note
Line impedance
To ensure trouble free operation we recommend the line impedance is less than 1% (RSC > 100).
Note
UL transient surge suppression requirements
To ensure that the electrical installation of this equipment complies with the UL requirements
for transient surge protection, the following requirement must be adhered to:
Transient surge suppression shall be installed on the line side of this equipment and shall be
rated 480 v (phase to ground), 480 v (phase to phase), suitable for overvoltage category III and
shall provide protection for a VPR maximum of 2 kv, type 1 or type 2 SPD application.
Note
Duty cycle calculation
If the duty cycles of the converter are not calculated properly, it could result in your application
not working efficiently and produce nuisance trips from overtemperature faults.
• Calculate duty cycles using the lowest rated component of the system - this should be either
the motor or the converter depending on the your application.
