2 Safety instructions
2.1 General notes
NOTICE
Warning of damage to property and/or the environment.
The product was in perfect condition with regard to safety features when it left the
factory.
To maintain this condition and to ensure safe operation, the user must follow the
instructions and observe the warnings in this manual.
2.2 Intended use
The mounting kits PR 97/00, ../01 are intended for weighing tasks, and must only be used
as such.
The mounting kits PR 97/00, ../01 are designed for installing the load cells MP 77.
The dimensions of all mounting and structural components must be calculated so that
sucient overload capacity is ensured for all loads which may occur while taking the
relevant standards into account. In particular, upright weighing objects must be
safeguarded against the weighing installation turning over or being shifted, thus
eliminating danger to people, animals, or goods even in the case of a break in a load cell
or mounting element.
Installation and repair work must only be carried out by expert/qualied personnel.
The mounting kits reect the state of the art. The manufacturer does not accept any
liability for damage caused by third-party system components or due to incorrect use of
the product.
2.3 Initial inspection
Check the contents of the consignment for completeness. Check the contents visually to
determine whether any damage has occurred during transport. If there are grounds for
rejection of the goods, a claim must be led with the carrier immediately. The
Minebea Intec sales or service organization must also be notied.
2.4 Before operational startup
NOTICE
Perform visual inspection.
Before operational startup as well as after storage or transport, inspect the
mounting kit visually for signs of mechanical damage.

3 Recommendations for installation
3.1 Load cell arrangement
Examples:
Load application
-The mounting kits are not provided with an integrated constrainer.
The horizontal forces thus aect the load cells directly with the permissible
eccentricity (approx. ±3 mm) fully utilized.
These forces must not exceed the maximum permissible horizontal load of the load
cells.
If there will be higher horizontal forces, external constrainers are indispensable.

5 Installation
5.1 Prior to mounting
5.1.1 Preparing the foundation/substructure
-The foundation for the mounting kit must be horizontal (use spirit level), at, and
rigid for the intended loads.
-The load distribution on the available load cells must be as even as possible to
prevent overload of the individual load cells.
-The substructure foundations/supporting surfaces for the mounting kits should be at
the same level, and the supporting surfaces of the weighing object (e.g. vessel feet)
must be arranged in parallel.
-If soft ller layers (e.g. made from rubber or plastic material) are used between the
mounting kit and vessel and/or between the mounting kit and substructure for
vibration dampening or for temperature insulation, a load compensating plate must
be provided between this soft ller layer and the mounting kit to ensure even load
application into the mounting kit.
The design of the insulation and compensation plates depends on the respective
application.
5.2 Tightening torques
The corresponding tightening torques are given in the following table.
Mounting parts Thread Tightening torque
Upper plate M8-A2-70 20 Nm
Lower plate M8-A2-70 20 Nm
Load cell M8-A2-80 30 Nm
Recommendation for the washers
of M8 mounting screws: DIN 7349 (d = 21, h = 4) or DIN 9021 or ISO 7093-2 (d = 24, h = 2)
5.3 Assembly
5.3.1 Safety instructions
WARNING
The vessel may turn over during mounting.
Securing the vessel against tipping is imperative.
Use an appropriate lifting jack.

NOTICE
Welding or lightning strike current owing through the cell can damage it.
All electrical welding on the weighing system must be nished before mounting the load
cells.
When installing the load cell, immediately bypass the load cell with the exible
copper strap provided for this purpose (included in the equipment supplied, see
Chapter 4.1).
During any additional electrical welding work near the load cell:
-Disconnect the load cell cables.
-Bypass the load cell using the exible copper strap.
-Make sure that the grounding clamp of the welding set is tted as closely as possible
to the welding joint.
5.3.2 Installing the mounting kit and inserting the load cell
Note:
Screw mounting of the upper and lower plates is described below.
The operations must be performed at all supporting points (e.g., vessel) of the weighing
object.
Requirements:
-All threaded holes for the upper plate are available in the vessel lug/vessel foot (see
Chapter 4.2).
-The lift-o protection is in the upper position.
Procedure:
NOTICE
Mounting kits are supplied ready to install.
The lift-o protection is in the upper position.
Do not adjust the lift-o protection before inserting the load cell.

Minebea Intec EN-13

1. Fit the mounting kit to the vessel foot. It is essential to observe the property classes
and tightening torques of the screws and the property classes of the washers (see
Chapter 5.2).
2. Place the vessel and mounting kit in the required position on the foundation/
substructure. Always make sure that the plates are in parallel and seated vertically
above each other.
3. Mark mounting holes for the lower plate (7).
4. Position the vessel with mounting kit so that drilling can take place.
5. Fasten the mounting kit to the foundation. It is essential to observe the property
classes and tightening torques of the screws and the property classes of the washers
(see Chapter 5.2).
6. Equalize the potential (15) between the upper plate (6) and lower plate (7).
7. Once all welding near and mounting work on the weighing object is complete, clean
the load cell base on the lower plate (7) and the recess for the load disc (12) in the
upper plate (6).
8. Insert the load disc (12) into the load cell and fasten with the nut.
9. Apply sucient grease to the contact surfaces between load cell/ load disc and upper
plate/load disc.

5.4 Check mounting
When all mounting kits have been installed, check them for proper mounting.
In particular, force shunts should be avoided.
It is essential to check:
-that the load cell has been inserted in the mounting kit without being canted.
-whether the upper and lower plates are mounted in a horizontal position.
-whether free moving space and the required play for thermal expansion are provided.
The free moving space which is required for displacement of the measured object due to
thermal expansion, vibration, etc. can be utilized without reducing the measuring
accuracy only if the load cell has been installed exactly.
To avoid force shunts, all incoming and outgoing lines (hoses, pipes, cables) must be
connected to the measured object with the greatest exibility possible.
The entire load must be supported by the load cells!
10. Mount the load cell (the arrow for the load direction must point downward) with the
screws (9) and the spacer (11) on the lower plate (7) so that the load disc (12) is seated
centrally in the recess in the upper plate (6). It is essential to observe the property
classes and tightening torques of the screws (9) and the property classes of the
washers (see Chapter 5.2).
11. Turn the nut (5) slowly downward to exert a load on the load cell and position the
centering guide (3) below the upper plate (6).
12. Check the horizontal position of the vessel in all directions using a spirit level. If
necessary, insert thin, deburred sheet-metal plates between upper plate (6) and
vessel foot, or between lower plate (7) and foundation.

The mounting kit is easy to clean. It can be spray-washed with water.
For this purpose, spray the water jet from top to bottom and around the mounting kit.
NOTICE
Some cleaning agents may not be compatible with the mounting kit material.
When using cleaning agents, ensure that their compatibility with the mounting kit
material has been tested and approved (see Chapter 4.3).
