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).

Electrical connection

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 intelligent power supply
(current monitoring designed for max. 4 A for
BNI IOL-...-P012 or 16 A for BNI IOL-...-P071).
► Connect the protective earth conductor to the FE
terminal.
► Connect the incoming IO-Link line to the sensor hub.

NOTICE
Loss of function and property damage
Improper installation, e.g. due to misconnection or
incorrect polarity of the connections, can result in a loss
of the function and property damage.
► Take measures to prevent misconnection or polarity
reversal.
► Prevent tampering at the connections.
► Never exceed the value of 36 V between any of the
pins.
If possible, supply power to the sensor/module
and actuator using an independent power source
to ensure independent operation in the event of a
power failure.
For UL: observe cable requirements and power
supply requirements (see section 10.7 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 three different supply voltages: U
– U supplies the module and also the connected
S1
sensors. (Variant ...P012).
– U supplies the module only (Variant ...P071).
S1
– U supplies the connected sensors. (Variant ...P071).
S2
– U is the supply of the digital outputs.
