Siemens UL 489, UL1066 specifications Output current Inrush current Type Order No

The + 24V DC connection must be connected to X8.3 and the ground of the 24V DC voltage supply must be connected to X8.4.

Selection criteria for the external power supply:

• First, the maximum continuous

current which the CubicleBUS

modules draw from the

A power supply must be selected in accordance with these two characteristic values. Several WL Circuit Breakers can be connected to one power supply. For this purpose, however, the total of the continuous currents must be considered. For example, the 6EP1332-2BA00 power supply can

be used with up to 3 ETUs and up to 16 CubicleBUS modules simultaneously. The 6EP1332- 1SH42 power supply can be used with 2 ETUs and up to 8 CubicleBUS modules simultaneously.

CubicleBUS supply must be

calculated. (see Table 2-23)

• Second, the peak inrush current

of all modules must be

calculated. The power supply

must be capable of bearing the

maximum peak inrush current

for a period of 100 ms.

2.5 A	< 30 A	Logo! Power	WLSITOP25
3.8 A	< 32 A	SITOP Power	WLSITOP1

Table 2-24A Siemens power supply can be selected for one or more WL Circuit Breakers.

One WLSITOP1 can power the following combinations of accessories
