3.9.1 Mains Power Supply
Power is fed to the machine via the mains
lead, to power an optional auxiliary output
panel, and/or lighting system.
Mains Power Indicator
The warning lamp (1) is illuminated, when
mains power is connected.
Current Leakage
NOTE
a) It is the user’s responsibility to ensure that the
total sum of leakage currents from additional
equipment plugged into the auxiliary sockets plus
the leakage current from the machine does not
exceed the values specified in any relevant
national standards that may apply in the country
where the machine is in use (see also, below)
b) Each socket is protected with a 5 A fuse in both
the live and neutral wire.
3.9.2 Auxiliary Power Supply Sockets
CAUTION
The requirements of IEC 60601-1-1 apply to any
device connected to the auxiliary sockets. Users
must be aware of the risks of increased leakage
currents when equipment is connected to the aux-
iliary power sockets.
The optional mains electricity outlet panel is
fitted to the rear of the machine.
The supply is controlled by an ON/OFF
switch (2), which also incorporates a circuit
breaker.
Switch labelling: I indicates On
0 indicates Off
CAUTION
In the event of malfunction of any device powered
by the auxiliary sockets, check if the circuit break-
er has tripped.
3.9.3 Flowmeter Bank Lighting
The lighting system is controlled by a three-
way switch (3).
The three positions denote:
A: Off
B: Bright light
C: Dim light
