Safety instructions – summarised, part 1
Safety instructions
We exclude any claims for damages of any kind for injury to persons and damage to equipment arising from non-observance
of the following safety instructions.
Use according to the intended purpose
Do not make any alterations to the machine and use only spare parts and accessories approved by Retsch. Otherwise the
Declaration of Conformity to the European directives declared by Retsch will lose its validity.
Furthermore this will lead to loss of any kind of guarantee claims.
Packing
Please keep the packing material for the duration of the guarantee period, since if you have a complaint and the equipment
is returned in inadequate packing your guarantee claim is at risk.
Transport
The PP40 must not be knocked, shaken or thrown during transport. Otherwise the electronic and mechanical components
can be damaged.
Lifting above head height is not permitted.
Temperature variations
If the PP40 is subjected to high temperature variations (e.g. during air transport) it must be protected against condensed
water. Otherwise there may be damage to the electronic components.
Supplied items
If the supplied items are incomplete and/or there is transport damage you must inform the transporter and Retsch GmbH
immediately (within 24 hrs). Later complaints may possibly be no longer considered.
Ambient temperature
If the temperature drops below or exceeds ambient temperature the electrical and mechanical components can become
damaged and performance data can change to an unknown extent.
Atmospheric humidity
At high atmospheric humidity the electrical and mechanical components can become damaged and performance data can
change to an unknown extent.
Electrical connection
If the values on the type plate are not observed the electrical and mechanical components can become damaged.
Only a qualified electrician should carry out electrical connection. Danger through current surge.
Important instructions for electrical connection
If your mains connection for the PP40 includes a fault-current protective system, fault throwing may result through the anti-
interference wiring of the frequency converter when this is switched on (switching on takes place each time the pressing
chamber hood is closed).
If the values on the type plate are not observed this can result in damage to the electrical and mechanical components.
Serial interface
The serial interface cables must not be longer than 2.5 m.
If the cables are longer this can result in disturbances during transmission of data.
Connecting the power supply
If the values on the type plate are not observed the electrical and mechanical components can become damaged.
Opening / closing / emergency unlocking
The emergency unlocking device must never be operated when the machine is running – only when the machine is at a
standstill and is disconnected from the mains supply.
Danger of injury through pressing.
Insertion of the pellet press ring at the PP40
Use only the specificated pellet press ring size.
Mechanical components can become damaged through using wrong ring sizes.
Preparation of the press process
Please take necessary measures, depending on the dangerous nature of your pressing material, to avoid danger to persons.
Check the quality of the press rings regularly.
Damaged rings can cause a damage to press tool.
The filling quantity shall be 8 – 12 ml.
The rings and press tool used could otherwise become damaged.
