Corrective Maintenance; Machines With A Certificate Extended With An "X - Siemens SIMOTICS XP 1MB 1 Series Operating Instructions Manual

Explosion hazard caused by incorrect painting
The paint coat can become electrostatically charged if an excessively thick paint coat is applied.
Electrostatic discharge can then occur. There is a risk of explosion if potentially explosive
mixtures are also present at this moment.
This can result in death, serious injury or material damage.
Risk of explosion as a result of processes with high levels of electrostatic charging
For paint finishes in explosion group III, the paint can be electrostatically charged as a result of
intensive dust turbulence or processes with high levels of electrostatic charging. Electrostatic
discharges can occur. Minimize the risk of electrostatic charging by applying effective measures
according to IEC 60079-32-1. This can result in death, serious injury or material damage.
Suitability test of the paint system for hazardous areas
Suitability certificates for the electrostatic suitability on explosion-protected machines are
available for paint systems ordered as standard. Non-standard or customer-specific paint
systems that have been used as well as subsequent painting require that customers perform
a suitability check regarding electrostatic charge according to EN/IEC 60079-0.

Corrective maintenance

Comply with the following when carrying out any work on the machine:
• Comply with the general safety instructions (Page 15).
• Comply with the applicable national and sector-specific regulations.
• When using the motor within the European Union, comply with the specifications laid down
in EN 50110‑1 regarding safe operation of electrical equipment.
If the motor has to be transported, please observe the information and instructions in the
"Transport (Page 42)" chapter.
9.3.1

Machines with a certificate extended with an "X"

The machine marking based on IEC / EN 60079–0 was supplemented by the "X" symbol.
• Perform maintenance, repair and modification work on explosion-protected machines in
strict compliance with the corresponding national health and safety legislation, the safety
instructions and descriptions in the general maintenance instructions.
