2.4 Work and operational safety
Warning
!
Carefully observe the following notes and the complete chapter 2 "Safety”,
page 8 !
• The local standards, rules and regulations relating to the installation
and operation of electrical appliances in potentially explosive atmo-
spheres must be observed (e.g. EN 60079-14 and EN 60079-17 in the
EU and ElexV in Germany).
• Appliances designed for use in potentially explosive atmospheres must
not be modified. The technical specifications for ambient conditions and
operation must be maintained and observed (see
chapter 8 "Technical
specifications”, page 31 ).
• Any work involving the units must be carried out by qualified electri-
cians (see chapter 3 "Assembly and installation”, page 12 , chapter 5
"Maintenance”, page 28 , chapter 7 "Troubleshooting”, page 31 ).
• The unit may only be used by qualified personnel trained for explosion
hazard areas.
• A "Connect/Disconnect Approval“ by the plant operator must be
obtained before carrying out any installation, assembly, service, repair
or maintenance work in potentially explosive atmospheres. Make sure
that there is no potentially explosive atmosphere prevailing in the wor-
king area (see
chapter 3 "Assembly and installation”, page 12 , chapter
5 "Maintenance”, page 28 ).
• Electrical systems used in explosion hazard areas must at all times be
in a technically faultless condition. Any defects must be repaired or
remedied immediately (see
chapter 4 "Operation”, page 25 ).
• The point of installation of the TCB030 Terrabox must be dry and the
indicator lamp must remain in full view. Avoid direct exposure to sun-
light (see
chapter 3.1.2 "Assembly”, page 13 ).
• The unit must be connected to the equipotential bond via the external
ground terminal (7, Fig. 4 / Fig. 5). In addition, the ground terminal
inside the enclosure must be connected to a PE conductor or a bonding
conductor (see
chapter 3.1.2 "Assembly”, page 13 ).
• Intrinsically safe circuits must be routed separately from non-intrinsi-
cally safe circuits (separate cable conduits/ducts). Crossing intrinsically
safe and non-intrinsically safe leads is not permitted. An equipotential
bonding connection (PA) must be established along the entire intrinsi-
