1.5.1 Important Warning Notices
WARNING!
Fire risk caused by inaccessible or missing disconnection device!
A fire risk exists in case of overheating, e.g. due to a device fault.
Furthermore, touching hot housing parts can cause burns. The mains switch
disconnects the device from the power supply and is used to switch it off in
case of danger. If the mains switch is not freely accessible, use the mains
plug to disconnect the device in case of danger.
» Always keep the mains switch or respectively mains plug freely accessible.
» If you can keep neither the mains switch nor the mains plug freely
accessible, install an additional disconnection device.
WARNING!
Electric shock caused by applied voltage!
» Always disconnect the instrument from the mains before maintaining or
cleaning it.
ATTENTION!
Damage to the device caused by insufficient opportunity for air
circulation!
Heat is created inside the device during operation. If the heat cannot escape
from the housing, a heat accumulation is being caused. This will overheat the
electronic parts inside the device and may result in a defect.
» Always keep free all air inlets and outlets of the device.
» Keep at least 50 mm distance to the wall when you set up the device.
» If the devices are in a system cabinet: Remove all covers of the system
cabinet before switching on the devices.
» If you notice a cooling fan failure, switch off the device immediately.
