Notes on the PoE power supply
WARNING
Danger from line voltage for devices with a 240 VAC power supply
This device can only function correctly and safely if it is transported, stored, set up, and installed
correctly, and operated and maintained as recommended.
Connecting and disconnecting may only be performed by an electrical specialist.
Connect or disconnect power supply cables only when the power is turned off!
WARNING
Devices with a 240 VAC voltage supply do not have an approval for hazardous areas
Devices with a 240 VAC power supply are not approved for use in hazardous areas according to
ATEX, IECEx, FM and UL HazLoc.
WARNING
Restricted access with power expansion
If you expand the PoE power of the device with 1 or 2 power supply units, operate the device
including the power supply units in a Restricted access area according to IEC 62368-1.
WARNING
Only use supplied cable to connect power expansion
A maximum of two SCALANCE PSR9230PoE power supply units are permissible for power
expansion of the devices. For the connection, use the supplied power cable (article no.
A5E49168671).
The cable is pre-assembled for connection to a switch of the SCALANCE XR-300PoE WG device
group.
To connect two SCALANCE PSR9230PoE power supply units to a switch of the SCALANCE
XR-300PoE WG device group, connect the two supplied power cables; see section "Power
cables for SCALANCE XR326-2C PoE WG". The work must be performed by a specialist according
to IEC 62368-1.
NOTICE
Securing cables with dangerous voltage
Make sure that the connector cannot be released accidentally by pulling on the connecting
cable. Lay the cables in cable ducts or cable channels and secure the cables, where necessary,
with cable ties.
