Safety Requirements
The equipment described in this manual has been designed and tested according to the

operation.
This might be the case when the equipment shows physical damage or is stressed beyond
tolerable limits (for example, during storage and transportation).
Important: Before opening the equipment, disconnect it from all power sources.
The equipment must be powered by a SELV* power supply. This is equivalent to a Limited Power

module is operated in extremely elevated temperature conditions, it is possible for internal and
external metal surfaces to become extremely hot.

SELV: conforming to IEC 60950-1, <60VDC output, output voltage galvanically isolated from mains. All
power supplies or power supply cabinets available from Siqura comply with these SELV requirements.
