Ambient Temperature
Units and systems by LightViper are generally designed for an ambient temperature range (i.e. temperature of the incoming air) of +5...+40
°C. When rack mounting the units, the following facts must be considered:
 The admissible ambient temperature range for operation of the semiconductor components is 0 °C to +70 °C
(commercial temperature range for operation).
 The air flow through the installation must provide that the outgoing air is always cooler than 70 °C.
 Average heat increase of the cooling air shall be about 20 K, allowing for an additional maximum 10 K increase at
the hot components.
 In order to dissipate 1 kW with this admissible average heat increase, an air flow of 2.65 m³/min is required.
Example: A rack dissipating P = 800 W requires an air flow of 0.8 * 2.65 m³/min which corresponds to 2.12
m³/min.
 If the cooling function of the installation must be monitored (e.g. for fan failure or illumination with spot lamps),
the outgoing air temperature must be measured directly above the modules at several places within
Earthing and Power Supply
Earthing of units with mains supply (class I equipment) is performed via the protective earth (PE) conductor integrated in the mains cable.
Units with battery operation (< 60 V, class III equipment) must be earthed separately. Earthing the unit is one of the measures for protection
against electrical shock hazard (dangerous body currents). Hazardous voltage may not only be caused by defective power supply insulation,
but may also be introduced by the connected audio or control cables.
This equipment may require the use of a different line cord, attachment plug, or both, depending on the available power source at
installation. If the attachment plug needs to be changed, refer servicing to qualified service personnel
If your unit mains supply is provided via a Neutrik PowerCon™ connector the following precautions must be followed:
 The PowerCon must be installed and fully engaged before AC power is applied to the unit.
 The unit must be disconnected from the mains supply before disengaging the PowerCon connector.
Class I Equipment (Mains Operation)
Should the equipment be delivered without a matching mains cable, the latter has to be prepared by a trained person using the attached
female plug (IEC320/C13 or IEC320/C19) with respect to the applicable regulations in your country.
Before connecting the equipment to the AC power outlet, check that the local line voltage matches the equipment rating (voltage,
frequency) within the admissible tolerance. The equipment fuses must be rated in accordance with the specifications on the equipment.
Equipment supplied with a 3‐pole appliance inlet (protection conforming to class I equipment) must be connected to a 3‐pole AC power
outlet so that the equipment cabinet is connected to the protective earth.
WARNING
If the ground is defeated, certain fault conditions in the unit or in the system to which it is connected can
result in full line voltage between chassis and earth ground. Severe injury or death can then result if the
chassis and earth ground are touched simultaneously.
