Damaging potential equalization currents due to different ground potentials
For electrical safety, the Bulkscan® LMS511 has been designed and checked accord-
ing to IEC 61010-1 and the Bulkscan® LMS111 according to EN 50178.
Risk of injury and damage caused by electrical current!
Potential equalization currents between the Bulkscan® and the peripheral devices can
have the following effects:
• Dangerous voltages on the metal housing, e.g., of the Bulkscan®.
• Incorrect function or irreparable damage to the devices.
•
Damage/irreparable damage of the cable shield due to heating and cable fires.
Make sure the devices connected together in a system (Bulkscan®, power supply,
encoder, PLC/host, etc.) all have the same ground potential.
Where local conditions are unfavorable and thus do not meet conditions for a safe
earthing method (same ground potential at all grounding points), take measures (see
"6.1.1 Avoiding potential differences“ on page 44).
