Precautions
Before installing, setting up or operating this equipment please ensure that you have read and fully understand all of this section and the “IMPORTANT SAFETY INSTRUCTIONS” at the front of this manual.
This equipment is supplied by a mains voltage that can cause electric shock injury!
The following special limitations must be observed in order to maintain safety and electromagnetic compatibility performance.
Safety warnings
This equipment is fitted with a mains power socket. For safety reasons the earth leads must not be disconnected.
Signal 0V is connected internally to the chassis.
To completely disconnect this equipment from the AC mains, while observing full safety precautions (see “Power” on page vii), switch off the mains at the mains outlet. It is now safe to isolate the unit by unplugging the mains lead from its rear panel.
To avoid electrical shock do not remove covers. Refer servicing to qualified personnel only.
The power supplies — even the DC ones — have a high current!
General precautions
The following information gives basic safety precautions that should be observed to reduce the risk of fire, electric shock and personal injury:
•Never operate damaged equipment and never operate equipment with damaged cables.
•Do not remove, obscure or deface any warnings or cautions.
Power
Please note that the system power supplies contain LETHAL VOLTAGES greatly in excess of the mains voltage and that its rails can produce extremely large currents that could burn out equipment and wiring if shorted. All
testing and servicing must ONLY be carried out by approved service engineers.
This apparatus should only be operated with the power supply connected to ground via the ground in the mains connector.
The internal power supplies are of the switch mode type that automatically sense the incoming mains voltage and will work where the nominal voltage is in the range 100VAC to 240VAC.
When removing the equipment’s electric plugs from the outlets, always hold the plug itself and not the cable. Pulling out the plug by the cable can damage it.
Never insert or remove an electric plug with wet hands.
Handling the equipment
Completely isolate the equipment electrically and disconnect all cables from the equipment before moving it.
When lifting or moving the equipment, always take its size and weight into consideration.
Do not insert your fingers or hand in any gaps or openings on the equipment, for example, vents.
Avoid inserting or dropping foreign objects, such as paper, plastic, metal etc., into any gaps or openings on the equipment, for example, vents. If this happens, immediately disconnect the equipment from the mains (see “Safety warnings” on page vii). Then, have the equipment inspected by the manufacturer's qualified service personnel.
