Maximum Operating Altitude
3.5.2.1. Ventilation Requirements
The 4Links RG platform products require unobstructed airflow to their rear ventilation grilles to allow the internal
fans to operate efficiently and thus to allow operation across the temperature range specified in section 3.5.2,
“Environmental Requirements”, above.
3.5.3. Power Supply
Power is provided by an external supply.
3.5.3.1. Supply Voltage
The power input is designed to accept DC 22 to 50 V, with either polarity.
The power input circuit is isolated from both the rest of the circuit and from the equipment case. The potential
difference between the power source and the equipment case (functional ground) must not exceed 50 V. A 1.2
MΩ resistor is fitted internally to prevent the build-up of a static potential difference between the power input
and the case.
Note: This input has limited surge protection and must be connected to a surge-free supply. The AC/DC adapter
supplied with the unit contains surge protection at its mains-voltage input and should be used where surge
protection is required.
