Second Generation MobileView Tethered Operator Terminal
MobileView 2711T Terminal Operation
See the MobileView 2711T Tethered Operator Terminal User Manual, publication
, for more handling instructions to avoid terminal malfunctions or damage.
Power Supply
The second generation MobileView 2711T terminal meets the Safety Class III requirements for
electrical shock in accordance with EN 61131-2. See
for the DC power
supply requirements for the second generation MobileView 2711T terminal, IP65 junction box,
and 22-pin connection cable.
Supply the junction box and terminal exclusively from power sources with safety extra-low
voltage (SELV) or protected extra-low voltage (PELV) circuit protection according to
EN61131-2.
Specifications of power supply lines in the connection cable are:
• Cross section: 26 AWG (0.126 mm
2
)
• Material: zinc-coated copper strand
• Line resistance: <136 Ω/km (<219 Ω/mi)
Enabling Switch
On the second generation MobileView 2711T terminal, the enabling switch consists of a 3-
position operating element with two independent circuits.
ATTENTION:
The 24V DC power supply to the control cabinet or operator panel must have a fuse
that is rated 3.15 A (maximum) and complies with UL 248.
Failure to install a fuse can result in fire from component failure.
ATTENTION:
Only the operator of the enabling device on the second generation MobileView
2711T terminal is allowed in the dangerous area or zone.
The enabling switch is only suitable as a safety device if the operator of the enabling switch on the
second generation MobileView 2711T terminal recognizes the dangerous situation and reacts in
time to avoid the danger.
Consider reduced speed of movements as a precautionary measure, which can be done through
the risk assessment of machinery.
