4 Installation and connection information
4.1 General information
Note:
When used in protection class "Ex nA" (non-sparking), a transient protective device must
be set to a level that does not exceed 140% of the peak voltage of 85 V.
When used in environments with ammable dust, electrostatic discharge from the
plastic label must be avoided.
-The safety instructions in Chapter 8must be followed!
-Only use the metal EX EMC cable glands provided by the manufacturer.
-Install the junction box so that the cable glands are on the bottom.
-Do not open the junction box when connected to the voltage supply.
Note:
At ambient temperatures >45°C, cables that are suitable for at least 85°C must be used.
4.2 Connecting intrinsically safe circuits
-The housing grounding or equalization line must be connected to the outside of the
housing under the ground screw.
-The junction box is suitable for use in potentially explosive atmospheres for
connection to intrinsically safe circuits. The circuits consist of
-the connection load cells (passive)
-the connection cable to an interface with an (active) intrinsically safe circuit, e.g.,
PR 1626/60 in connection with a downstream device.
The intrinsically safe circuit consists of the circuits for the supply, sense, and
measuring voltage.
-It is not permissible to connect multiple active intrinsically safe circuits in the junction
box.
-When used in zone 20, the accumulated dust must not exceed a thickness of 5 mm.
-When used in zone 2, ensure that no voltage peaks more than 40% above the
nominal voltage can occur.

4.4 Cable gland
The cables have to be fed into the device via glands to ensure leak-tightness. The
following cable diameters are suitable: 612 mm for gland M20 and 36 mm for cable
gland M12.
The enclosed M20 cable gland is suitable for cable diameters 913 mm.
The cable wires are connected to the terminals inside the device.
NOTICE
For protection against dust and moisture during transport and installation, the
cable glands are tted with a polyethylene cover.
For full IP protection, operation with the dust protection cover tted is not permitted.
Remove the dust protection cover.
If a cable gland is not used, it must be sealed with a supplied locking pin.
NOTICE
Property damage is possible.
Regularly check the tted cable gland for tightness and re-tighten it, if necessary.

5 Cable connections
5.1 General information
Cable entry must be from below.
Fit the wires and screen of the connection cable with wire end ferrules. This is not
necessary for the load cell cables.
Connect the wires to the terminals according to the color coding .
Place the cable screens of the connection cable and load cell cables on the yellow
terminals. The terminals are connected with the housing via overvoltage conductor.
Connect the screens on the other side of the connection cable with the equipotential
bonding terminal of the downstream device (see instrument manual) as described in
Chapters 5.3 and 5.4.
WARNING
When installing in potentially explosive atmospheres:
It is imperative that you follow the application-dependent installation instructions!
Always check whether it is permissible to bilaterally connect the screens to the
equipotential bonding.
Note:
The calibration certicate, installation manual and data sheet of the load cell contain
information about how to connect the load cell cable screen with the load cell housing.
5.2 Connecting cables
To connect the junction box to the device, connection cable PR 6135/..or PR 6136/.. (for Ex
zone) must be used; max. length: 300 m.
5.3 Cable connections

All components are only shown schematically.

5.4 Equipotential bonding conductor
NOTICE
It is especially important that the ground is connected correctly to the components
and the cable junction box.
You must also ground the device separately and ensure the power supply is properly
shielded against the eects of lightning. Simply connecting the protective grounding
conductor is not enough!
If the installation is not carried out according to our instructions, this voids the
warranty. In particular, the entire installation, including the power supply, must be
suciently protected against lightning.
In Ex areas, equipotential bonding must be established to avoid any compensatory
currents between the individual conducting system components.

5.5 Electronic corner correction
5.5.1 General information
Load cells from Minebea Intec are manufactured according to high quality standards and
have very precisely balanced output values.
Nevertheless, mechanical imbalances may cause impermissibly large corner load errors,
which must be compensated for by soldering in resistors.
Note:
The soldering studs for the resistors are short-circuited at the factory.
The load cells must be correctly installed and precisely aligned in order to achieve good
measuring results and good results with corner loads. For this reason, if you notice a
corner load error, always check the installation and alignment of the load cell rst.
If necessary, mechanically adjust the height (see load cell installation manual).
NOTICE
Loss of verication accuracy
Contact problems cause unstable signals. The consequences are wandering zero points
that lead to loss of verication accuracy.
Do not use a potentiometer.
Only use resistance values of 05.62 Ω (1%, P70 = 0.6 W) of size MBB0207
(approx. 2.5 × 6.5 mm) or CECC B.
5.5.2 Procedure
The corner load error can be minimized by selecting reference cell to be load cell with the
lowest displayed load.
The other load cells are adjusted to value displayed on the reference cell by additional
resistors at the input of the load cells.
The electronic corner correction makes it possible to reduce the sensitivity of each
separate load cell individually.
The following formula is used:
R Resistivity added to the input circuit of the load cell
(the resistivity is normally <7 Ω)
Weight nom Weight value in the display
Weight target Weight of applied load
RLC Input impedance of the load cell
