Safety Instructions
These safety instructions apply to the installation, operation, maintenance and repair of the equipment
1)
Install the equipment in compliance with applicable laws, rules and regulations, ordinances and standards�
Inparticular, be sure to conform to the European Standards EN 60079-14 (Electrical apparatus for use in potentially
explosive gas atmospheres)�
2)
Be sure to follow the installation, operating, maintenance and servicing instructions given in the manuals supplied�
3)
The PMA35001-Y must be installed so that the IP protection rating (IP4x) is maintained� Reduce the risk of
mechanical damage to a minimum� Take measures to ensure that neither foreign objects (particles) nor direct
or indirect water spray can penetrate into the equipment� Connections not in use must be sealed by appropriate
sealingcaps (do not remove using pressure)� Exposure to UV radiation is not allowed!
4) The
external connecting cables must be installed in a protective tube and secured
to prevent damage and
stress caused by strain� The cable glands must be secured to prevent them from working loose�
5)
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!
Never connect or disconnect cables while the
power is on in a hazardous area!
6)
If the equipment does not operate properly, unplug it immediately from line power (mains supply)!
7)
All metal parts
(housing, column, load plate, bench, etc�) must be electrically connected to the
terminal for
theequipotential bonding conductor (PA)
� The equipment operator is obligated to connect a lead with a gauge
of atleast 4 mm
2
(cross section) to the PA terminal located on the side of the housing� The low resistance of this
connection to the PA busbar 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 if no impermissible difference in voltage is generated and
the shielding is able to conduct any equipotential current�
8)
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�
9)
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�
10) Use equipment only in the temperature ranges indicated� Avoid exposing the equipment to heat�
11) If you wish to use other category 3 equipment in a zone 2 hazardous area, be sure that it has the required group for
gases and temperature class� The outputs must have EEx nA electrical circuits�
12) The equipment operator is responsible for any non-Sartorius cables used�
13) Check the Ex approval marking (particularly the group for gases and temperature class) on all equipment in the
hazardous area before operation to ensure that this category 3 Ex approved equipment is permitted to be operated
in this area�
14) At reasonable intervals, have your equipment installation checked for proper functioning and safety by a trained and
certified technician�
15) If your equipment needs to be repaired, use only genuine replacement parts supplied by the manufacturer!
16) 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 for zones 2 and and in the forfeiture of all claims under the
manufacturer's warranty� Only authorized specialists may open the equipment�
17) Modifications, including those to be carried out by Sartorius employees, may be permitted only after the express
written authorization has been obtained from Sartorius�
18) The data cables connected to the equipment are considered non-igniting EEx nA circuits� These connections must be
secured to prevent accidental disconnection and may be plugged in or disconnected only if the power is completely
shut off� Unused outputs must be sealed so that the IP4x protection is maintained�
