Power Supply Requirements

Electrical Specifications

24V dc Power Supply

Grounding

ATTENTION

Publication 2727-QS002E-MU-P

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

Connect Earth Ground to the Junction Box using the Earth

Ground Screw (shown on page 14).

• 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 directly of the MobileView

terminal (without the MobileView Connection Cable) is

+24V dc (supply voltage range: 18 to 32V dc).

Typical current consumption is:

- 300 mA at 24V dc

-400 mA at 18V dc

When planning the power supply, take into account the

voltage drop on the Connection Cable.

Specification of power supply lines in this cable:
