Electrical Specifications
24V dc Power Supply Use a 24V dc Safety Extra Low Voltage power
supply.
Supply Voltage Range: 18V dc to 32V dc
Current Consumption: 300mA at 24V dc
Peak Inrush Current: 5.6 A maximum
Grounding Connect Earth Ground to the Junction Box using
the Earth Ground Screw (shown on previous
page 2-4).
ATTENTION
!
• The device meets the safety class III in
accordance with EN 61131-2 and EN 50178. The
24V power supply for the equipment must
provide appropriate isolation between the
safety-extra-low-voltage circuits and
dangerous-contact voltage circuits (for example,
by safety transformers or similar facilities).
• The power supply circuit must be protected with
a 3.15 A fuse.
• The nominal supply voltage of the MobileView
terminal (without MobileView Connection Cable)
is 24V dc (supply voltage range: 18-32V dc) with
a typical input current of 300 mA.
When planning the power supply, consider the
voltage drop in the connection cable.
Specifications of power supply lines in the
connection cable are:
- Cross section: AWG24 (0.24mm
2
)
- Material: zinc-coated copper strand
- Line resistance:
< 90 Ohm/km ( < 145 Ohm/mile)
