Caution
The rated power of the PS791-1PRO is 9 W. Higher power consumption
causes a thermal overload of the device that can cause damage or destruction of the PS791-1PRO.
Installation and Commissioning
Wall-mounted,S7-300 Standard Rail or DIN Rail
To install the PS791-1PRO on a wall, you require four M4 screws.
Note
If you mount the device on a wall, the wall must be capable of supporting at
least four times the weight of the device (weight of the device 750 g).
The device can be installed on an S7-300 standard rail by hanging it on the
rail using the upper bracket. With the preinstalled screw, the device is
screwed into the lower rail groove.
It is also possible to install the device on a DIN rail using the slider on the
rear of the device.
The PS791-1PRO can also be mounted on the housing of a SCALANCE
W788 / SCALANCE W744 or SCALANCE X208PRO from below using 4
M4X80 screws (not supplied).
Accessories for 24 V Connection
To connect the M12 socket X2 with the SCALANCE products X788 and
X744 and the SCALANCE X208PRO, you can use the supplied M12
power cord. As an alternative, you can assemble your own cable. The pin
assignment of the X2 connector is described in the section Technical
Specifications.

Warning
If the power supply cable is not perfectly sealed or the cable socket is not
screwed on fully, there is a risk of danger to life due to the line voltage, if
the PS791-1PRO is subjected to sprayed water or dampness!
Put the PS791-1PRO power supply unit into operation only when the following conditions are met:
•
Use only power cables with a sealed connection to the cable socket.
Refer to the assembly instructions for the cable socket in these operating instructions.
•
The union nut of the cable socket must be screwed onto the thread of
the X1 male connector completely so that the seal of the cable socket
is correctly in position.
•
A suitable socket with seal is screwed onto the X2 male housing connector for the output voltage or the male housing connector is covered
by a protective cap.
Warning
The device must be connected and fused in the primary circuit according to
the local regulations. The current consumption at 9 W rated load and 110 V
input voltage is approximately 0.2 A (at 230 V input voltage 0.1 A). The
short-time peak making current is 16 A.

To connect to the line voltage, use a three-core cable with 0.5 - 2.5 mm²
core cross-sectional area and 6 - 9.5 mm outer diameter.
Follow the steps below to connect the cable socket to a power supply cable.
1. Unscrew the socket sleeve from the socket. Open the strain relief
clamp.
2. Remove the cable bushing screw along with the seal from the socket
sleeve.

3. Feed the power supply cable through the cable bushing screw, the
seal and the socket sleeve.
4. Screw the wire end ferrules of the cable tight according to the pin
designations shown on the terminals. Make sure that the protective
earth of the power cable is somewhat longer than L1 and N.

5. Following this, strain relief clamp must be tightened so that the insulation of the power cable is completely covered by the clamp.
The insulation of the power cable must be flush with the strain relief
clamp.
6. Make sure that the power cable is not squashed by the strain relief.
Any strain applied to the cable must not, however, affect the conductors or screw terminals.
7. Screw the socket sleeve onto the socket.
8. Insert the seal into the socket sleeve until the seal makes contact
with the shoulder.
9. Screw the cable bushing into the socket sleeve until you are sure
that the seal is pressed in to surround the cable firmly. This is intended to prevent dampness and sprayed water entering the connector.
