Installation and connection

5.1 Installation
For dimensions, see Fig. 4-1 on page 8.
You can find mounting accessories under
www.balluff.com on the product page.
► Fasten the module with 2 M6 screws and a tightening
torque of 3 Nm using the mounting holes (see Fig. 4-2
on page 8).
Requirements for complying with the protection
classes:
For IP68/IP69K, all plugs and caps must be properly
connected and the tightening torque of 0.6 Nm must be
observed (see data sheets of connectors and caps).

5.2.1

Power supply

NOTICE
Unwanted voltage dips
Non-separated electric circuits of the power supplies for
sensor and actuator can lead to unwanted voltage dips
of the sensor supply when switching actuators.
► Fuse the power supplies for sensors and actuators
separately.
► Make sure that the power supply of the device is
sufficiently dimensioned to cover start-up and peak
currents and design the fuse protection concept
accordingly.
NOTICE
Overcurrent
Defective or missing fuses in the power supply for sensor
and actuator will damage them.
► Use a fuse or an intelligent power supply (current
monitoring designed for a maximum of 4 A).
► Connect the protective earth conductor to the FE
terminal.
► Connect the incoming IO-Link line to the sensor hub.
For UL: Observe cord requirements and power
supply requirements (see chapter 10.7.2 on
page 21)!
The supply voltage for the module is provided via the
IO-Link interface from the higher-level IO-Link master.
There are two different supply voltages: U
– U supplies the module and also the connected
S
sensors.
– U is the supply for the digital outputs (only on
A
BNI IOL-727-S51-P012).
