tal use:
- Before connection.

• Only operate the appliance when completely assembled. Do not drill into
or interfere with the explosion-proof housing in any way.
• Observe the nominal voltage (24V DC, stabilised).
• Please note: The application of voltages >26 V will break the zener barrier
and permanently damage the signal tower.
