Sartorius PMA.Evolution Instrucciones De Instalación página 59

These safety instructions apply to the installation, operation, maintenance and repair of the equipment
Be sure to follow the installation, operating, maintenance and servicing instructions given in the manuals supplied.
1) Install the equipment in compliance with applicable laws, rules and regulations, ordinances and standards. For
ATEX: In particular, be sure to conform to the European Standards EN 60079-14 (Explosive atmospheres – Part
14: Electrical installations design, selection and erection). Be sure to follow the installation, operating,
maintenance and servicing instructions given in the manuals supplied.
2) No connection to any device that uses or generates in excess of 250Vrms or 250Vdc.
3) All metal parts must be electrically connected to the terminal for the equipotential bonding conductor (PA).
The equipment operator is obligated to connect a lead with a gauge of at least 4 mm² (cross section) to the PA
terminal located on the housing of the Ex-Link converter and scale. The low resistance of this connection to
the PA bus bar must be checked when the system is installed at the intended place of use. The shielding of the
connecting cables may only be used for grounding when no impermissible difference in voltage is generated
and, if necessary, the shielding is able to conduct the equipotential current.
4) Only the Sartorius cable type YCC01-0052Mxx (XX = 10 for 10m, 20 for 20m; 30 for 30m) may be used.
Maximum cable length: 100ft (30.5m). The data cable connected to the scale (weighing unit) is considered as
intrinsically safe circuit. Check the correct function of the data transfer before you use the equipment in a
hazardous location. The equipment operator is responsible for any non-Sartorius cables used.
5) If the Ex-Link Converter YCO14-Y is installed in Zone 2, the installation must be done in such a way that the
pollution degree 2 of the YCO04-Y board is guaranteed.
6) If the Ex-Link Converter YCO14-Y is installed in Zone 2, it must be connected via an USB cable to a apparatus
with intrinsically safe (Ex ic) output. The input parameters of the YCO14-Y in type of protection Ex ic IIB are
Ui = 17.0V, Ii = 2.0A, Pi = any, Ci = 5.7μF, Li = 0mH or Ui = 16.0V, Ii = 2.5A, Pi = any, Ci = 5.7μF, Li = 0mH.
7) In Zone 2 the „USB Power" port may not be used.
8) If the cable contains no Ex ic circuits, the cable must be protected against unintended release by use of
Sartorius „Strain Relief for USB Cord" type YSR01.
9) The equipment shall be installed in such a way that it is protected against the entry of solid foreign objects or
water capable of impairing the safety of the apparatus. Reduce the risk of mechanical damage to a minimum.
10) Exposure to UV radiation is not allowed!
11) Use equipment only in the temperature ranges indicated. Avoid exposing the equipment to heat.
12) The connecting cable of the display unit must be prevented against damage and stress caused by strain.
13) If the equipment does not operate properly, unplug it immediately from line power (mains supply)!
14) Avoid generating static electricity. Use only a damp cloth to wipe down the equipment. The equipment
operator shall be responsible for preventing any risks caused by static electricity.
15) Keep chemicals and other agents, which can corrode the housing seals and cable sheaths, away from the
equipment. These agents include oil, grease, benzene, acetone and ozone. If you are not sure about the safety
of a certain substance, please contact the manufacturer.
16) At reasonable intervals, have your equipment installation checked for proper functioning and safety by a
trained and certified technician.
17) Prior to opening the equipment, disconnect the power supply or make sure that there is no potentially
explosive atmosphere or any other explosion hazard in the surrounding area!
18) WARNING: SUBSTITUTION OF COMPONENTS MAY IMPAIR INTRINSIC SAFETY. If your equipment needs to be
repaired, use only original spare parts supplied by the manufacturer!
19) Any tampering with the equipment by anyone, other than repair work done by authorized Sartorius service
technicians, will result in the loss of EX conformity and in the forfeiture of all claims under the manufacturer's
warranty. Only authorized specialists may open the equipment.
20) Modifications, including those to be carried out by Sartorius employees, may be permitted only after the
express written authorization has been obtained from Sartorius.
