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.
