4.2 Personal Protection
Danger of serious injury from electric shock!
Before starting any servicing work, verify that all power supply lines are off-circuit and cannot be
energized while working on the light!
The building installation must include a disconnector (e.g. circuit breaker) allowing all-pole and
simultaneous disconnection of all electric circuits of the light (100–240 V mains supply, 24–36 V direct
voltage supply) from the power source to which the light is connected. The switch or circuit breaker
used must comply with IEC 61058-1 requirements regarding creepage distances and clearances or
must be UL-listed.
To prevent any risk of electric shock, be sure to connect the lights only to power supply systems
providing protective grounding.
For mobile lights with detachable mains plug (power supply cable), free access to the socket-outlet
must be possible at any time to ensure that the light can be easily disconnected from the power
supply.
The light’s direct voltage supply must meet the requirements for safety extra-low voltages (SELV) acc.
to IEC 60601-1 (VDE 0750).
Be sure to switch off the building-side circuit breaker before performing any servicing work on the
light system!
The mains connecting wires must be protected against accidental loosening or fracture at the
terminal.
Danger of serious injury from
defective lights!
ing lights can damage the health or even threaten the lives of users and/or patients!
• Therefore, never operate defective lights!
ay be used only at a safe distance from openings or surfaces emitting or releasing
