All SITOP and LOGO!Power supplies are built-in devices. Com-
pliance with the pertinent country-specific regulations is essen-
tial for installation and electrical connection of the devices.
During installation, protective gear and isolating gear must be
provided for activating the power supply.
Power supply units cause a current inrush immediately after con-
nection of the input voltage due to charging of the load capaci-
tor, however, it falls back to the rated input current level after a
few milliseconds. Aside from the internal impedances of the
power supply, the inrush current is dependent on the size of the
input voltage applied as well as the source impedance of the
supply network and the line impedance of the supply line. The
maximum inrush current for the power supplies is specified in
the applicable technical data. It is important for dimensioning
upstream protective devices.
Single-phase SITOP and LOGO!Power supplies are equipped
with internal device protection (fuses). For connection to the
supply system, only one protective device (fuse or MCB) must
be provided for line protection in accordance with the rated cur-
rent of the installed cable. The circuit-breakers recommended in
the data sheets and operating instructions have been selected
such that even during the maximum current inrush that can oc-
cur under worst-case conditions on switching on the supply volt-
age, the circuit-breaker will not trip. A two-pole connected min-
iature circuit-breaker is required for the connection of certain
device types.
3-phase SITOP power supplies do not have internal device
protection. The up-circuit protective device (3-phase coupled
miniature circuit breaker or motor protection switch) protects the
cables and devices. The protective devices specified in the data
sheets and operating instructions are optimized to the charac-
teristics of the relevant power supplies.
