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 95T/00, ../01, ../10, ../11 are intended for weighing tasks, and must
only be used as such.
The mounting kits PR 95T/00, ../01, ../10, ../11 are designed for installing the load
cells MP 58T, MP 79T.
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 and constrainer arrangement
Examples:
Key
Do not constrain this position.
Constrainer
Load application
Possible direction of movement
3 Recommendations for installation Mounting kits PR 95T/00, ../01, ../10, ../11
Minebea Intec EN-5

-To ensure the required free moving space of the weighing facility, a maximum of
3 mounting kits with constrainer may be used to constrain a weighing object.
Round containers are the exception (image ① and ②). In this case, any number of
constrainers can be installed, provided that they are tangentially aligned.
Special mounting kits are available for weighing points without constrainers.
Alternatively, the constrainer can simply be removed.
With elastic constructions, it may be necessary to deviate from this recommendation
in order to guarantee the weighing object has sucient stability.

The mounting kits are equipped with an internal lift-o protection, i.e. no additional
borings apart from the mounting holes in the vessel foot are required.

3.2.2 Jack-up with centering guide
Note:
If the weighing object is fully displaced, the jack-up with the centering guide will be
restricted in terms of functionality.
Lift the vessel as follows:
Use the load cell as follows:
1. Turn the nut (5) until the load cell is unloaded and can be removed together with the
upper load disc.
2. Insert the load disc into the load cell.
3. Insert the load cell into the mounting kit.
4. Load the load cell slowly and adjust the built-in lift-o protection as described in
Chapter 3.2.3.

3.2.3 Adjusting the built-in lift-o protection
1. Turn the nut (5) downwards.
2. Check that the distance A = 1–2 mm.
Mounting kits PR 95T/00, ../01, ../10, ../11 3 Recommendations for installation
EN-8 Minebea Intec

If the distance is too short:
3. Turn the nut (5) upwards to loosen the nut (4).
4. Turn the screw (2) upwards to congure the safety distance "A".
5. Re-secure the nut (4).
6. Turn the nut (5) downwards again.

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

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.
WARNING
Warning of hazardous area and/or personal injury
The locking washers of the constrainers may only be used once.
Insert new washers in case they have been damaged or removed. Spare parts, see
Chapter 8.
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.
