A 20 – Safety
Connection
• The equipment must be connected to a mains socket that has an earth contact.
• Protect the power cord from being walked on or pinched particularly at plugs, convenience receptacles, and the
point where they exit from the apparatus.
• Lay all connection cables so that they do not present a trip hazard.
• Whenever working on the inputs and outputs of the equipment switch off power.
• Check whether the connection figures comply with the existing mains supply. Serious damage could occur due
to connecting the system to the wrong power supply. An incorrect mains voltage could damage the equipment or
cause an electric shock.
• Please note that different operating voltages require the use of different types of power cable and plugs.
Please refer to the following table:
Voltage Power plug according to standard
110 - 125 V UL817 and CSA C 22.2 no 42.
220 - 230 V CEE 7 page VII, SR section 107-2-D1/IEC 83 page C4.
240 V BS 1363 (1984): "Specification for 13A fused plugs and switched and un-switched socket
outlets."
• If the equipment causes a blown fuse or a short circuit, disconnect it from the mains and have it checked and
repaired.
• Do not hold the mains cable with wet hands. There must be no water or dust on the contact pins. In both cases
you could receive an electric shock.
• The mains cable must be firmly connected. If it is loose there is a fire hazard.
• Always pull out the mains cable from the mains and/or from the equipment by the plug – never by the cable. The
cable could be damaged and cause an electric shock or fire.
• Do not use the equipment if the mains plug is damaged.
• If you connect defective or unsuitable accessories, the equipment could be damaged. Only use connection
cables available from or recommended by beyerdynamic. If you use cables you have made up yourself, all claim
to warranty is null and void.
• In order to disconnect the receiver from AC power, switch it off and disconnect the power plug from the power
socket.
Maintenance
• Only clean the equipment with a slightly damp or dry cloth. Never use solvents as these damage the surface.
Troube shooting and servicing
• Do not open the equipment without authorisation. You could receive an electric shock. There are no user-
serviceable parts inside.
• Leave all service work to authorised expert personnel.
