Installation and connection

6.1

Preparing for installation

When selecting the installation location, ensure that there is
sufficient distance to workplaces where people are
permanently present (see chapter 2 on page 7).
Furthermore, it must be ensured that the read/write head is
mounted in such a way that the main beam direction of the
antenna is optimally aligned with the location to be
identified and that the line of sight between the read/write
head and the data carrier is free of metals or other
electromagnetically effective materials. If this cannot be
ensured, the optimum functioning of the read/write head
may be impaired.
6.2

Installation

CAUTION
Ultra high frequency electromagnetic waves
The antenna of the read/write head emits ultra-high-
frequency electromagnetic waves. Additional measures
must be taken to prevent health hazards.
► Determine the mounting position of the antenna in
such a way that a safety distance of at least 20 cm
between the antenna and workplaces of persons is
ensured.
► Make sure that people do not stay in the vicinity of
the antenna for an extended period of time.
► Use suitable measures to shield areas that are
explicitly not to be covered.
For dimensions and tightening torques, see
Fig. 4-3 on page 9.
The devices must be permanently installed. The
corresponding fastening nuts must be tightened to the
specified tightening torques.

can be output (see configuration guide).
► Connect data line to IO-Link master (for connection
cables and accessories, see www.balluff.com on the
product page).
6.4

Shielding and cable routing

Both unshielded and shielded cables can be used to
connect the devices. In systems with strong
electromagnetic interference, it is recommended to use a
shielded cable. The cable must be routed tension-free.
In addition, grounding the BIS U-4A7 housing can minimize
the influence of electromagnetic interference.
