1 Safety information for operation in the
Exarea
▲ The PBK9-series high precision weighing platforms except PBK989-XS0.6 provide
options for operation in Category3 or Category 2 / DIV 1 hazardous areas (gases and
dusts). There is an increased risk in injury and damage when using the explosionprotected weighing platforms in a potentially explosive atmosphere. Special care must
be taken when working in such hazardous areas.
▲ Any protective foils present in the hazardous area, e.g. on the load plate, must always
be removed.
▲ In hazardous areas, the weighing platforms may only be installed, maintained and
repaired by authorized METTLER TOLEDO service personnel.
▲ No modications may be made to the weighing platform and no repair work may be
performed on the system modules. Any weighing platform or system modules that are
used must comply with the specications contained in the installation instructions.
Non-compliant equipment jeopardizes the intrinsic safety of the system, cancels the
"Ex" approval and renders any warranty or product liability claims null and void.
▲ The safety of the weighing system is only guaranteed when the weighing system is
operated, installed and maintained in accordance with the respective instructions.
▲ Also comply with the following:
– the instructions for the system modules,
– the regulations and standards in the respective country,
– the statutory requirement for electrical equipment installed in hazardous areas in
the respective country,
– all instructions related to safety issued by the owner.
▲ The explosion-protected weighing system must be checked to ensure compliance with
the requirements for safety before being put into service for the rst time, following any
service work and every 3 years, at least.
▲ Prevent the build-up of static electricity.
– Always wear suitable working clothes when operating or performing service work
in a hazardous area.
– Avoid strong mechanical rubbing of the powder-coated surfaces against any
material when operating in Category3 or Category 2 / DIV 1.
– Only use the weighing platforms when electrostatic processes leading to propagating
brush discharges are impossible.
▲ Do not use protective coverings for the devices.
▲ Avoid damage to the system components.
▲ If system damage occurs, the system must be put out of operation immediately.
▲ Damaged system components must be replaced immediately.

Safet y information for operation in the Exarea
PBK9-series 30233012B
▲ Only install or perform maintenance work on the weighing system in the hazardous
areas if the following conditions are fullled:
– the intrinsically safe characteristic values and zone approval of the individual
components are in accordance with one another,
– the owner has issued a permit ("spark permit" or "re permit"),
– the area has been rendered safe and no explosive dust is present and the owner's
safety coordinator has conrmed that there is no danger,
– the necessary tools and any required protective clothing are provided (danger of
the build-up of static electricity).
▲ The explosion protected PBK9-series high precision weighing platforms may only be
operated in hazardous areas of Category3 or Category 2 / DIV1 in conjunction with
weighing terminals that have the appropriate approval and interface specication.
▲ The certication papers (certicates, manufacturer’s declarations) must be present.
▲ Before setting up the system secure the connection between weighing terminal and
weighing platform.
▲ Lay cabling securely so that it does not move and effectively protect it against damage.
▲ Only route cables into the housing of the system modules via the approved earthing
cable glands and ensure proper seating of the seals.
▲ The connection cable may not be separated from the weighing terminal while it is
energized.
▲ Make sure that no conductive dusts exist when removing the plug of load cell.
▲ Only use METTLER TOLDEO approved and marked connection cables.
▲ Secure M12 connectors via hexagon nut and appropriate tools.
Torque range: 1.0 to 1.2Nm.
▲ Connect the weighing platform with an equipotential bonding conductor to the system
safety ground.
▲ Protect the M12 ange socket and the cable connector effectively against mechanical
damage by using the assembled protective bracket.
▲ Avoid direct sunlight radiation.

2 Installation
2.1 Preparatory work
2.1.1 Selecting installation location
▲ The foundation at the installation location must be capable to safely support the
weight of the weighing platform at its support points when it carries the maximum
load. At the same time, it should be so stable that no vibrations occur during weighing
operations. These requirements also apply when the weighing platform is integrated in
conveying systems and the like.
▲ Ensure that the ground at the installation location is even.
▲ Ensure that there are no vibrations from machines near the installation site.
▲ Ensure that there are no drafts at the installation site.
EXPLOSION HAZARD
PBK989-XS0.6 is not approved for hazardous areas.
▲ Do not use PBK989-XS0.6 in any kind of hazardous areas.
2.1.2 Ambient conditions
• Use powder-coated/enamelled weighing platforms only in a dry environment.
• In a damp environment, in wet operation or when working with chemicals: Use
stainless-steel weighing platforms.
2.1.3 Accessories
➜ Completely unpack the accessories provided with the weighing platform.
– 1 bottle of oil, suitable for foodstuffs
– 1 set of measuring data signs for selectable congurations
– Optional: ACC409xx-SICSpro-IDNet converter (incl. identcard kit, not for Category2/
DIV1)

2.2.5 PBK98_-CC150 / PBK98_-CC300
1. Remove the weighing platform from the packing.
2. Remove the load plate by pivoting the two side handles (1) outward.
3. Remove the transport locks (2 x 2 cardboard strips between lever and base frame +
4 cardboard angles in the corners).
4. Replace the load plate (2) so that the symbol is located above the level indicator.
5. Make sure that the load supports (3) in the corners of the weighing platform are
vertical.
2.3 Levelling
Notes
• Only weighing platforms that have been levelled precisely horizontally provide accurate
weighing results.
• Redo levelling when the weighing platform has been moved.
1. Level the weighing platform with the 4 foot bolts (1) using the level indicator (2): The
air bubble of the level indicator must come to rest within the ring marking.
2. Ensure even contact of the foot bolts. Every foot must stand safely and must have full
contact with its entire surface. Check the stability of the weighing platform by pressing
down on or rocking it at the corners.
3. Lock the foot bolts with the nuts.

2.4 Lengthening and installing connection cable
The connection cable may be lengthened.
Standard version up to 100 m
Ex version up to 50 m
➜ Route the connection cable directly out of the weighing platform to the weighing
terminal or the ConBloc (PBK98_APW weighing platforms only).
CAUTION
If the cable is laid in a pipe, ensure that the pipe is of a sufcient diameter.
2.5 Equipotential bonding in hazardous areas
EXPLOSION HAZARD
▲ Always use equipotential bonding in hazardous areas.
▲ Use only cables with cross section 4 mm2.
The equipotential bonding must be installed by a professional electrician when using the
weighing platform in hazardous areas. METTLER TOLEDO Service only has a monitoring
and consulting function here.
