Electrical hazards
• Ensure that the multiplexer and all associated
ancillary equipment are connected to a suitable
mains network power supply.
• Disconnect the multiplexer from the power supply
(and from all other devices) immediately if the
presence of smoke or an acrid smell suggests that
a malfunction has occurred.

technicians are authorized to carry out installation
or servicing work on this unit.
• If you intend to take the multiplexer out of service
for an extended period, disconnect it from the
power supply and ensure that it is stored in a dry,
weather-protected location.
• Do not allow liquids of any type to get inside the

at once and have it examined by the installer or a
qualified service technician.
