Installation Instructions
MobileView Junction Box
(Catalog Number 2727-MRJB2)
English
The MobileView Junction Box (2727-MRJB2) integrates the following terminals into
the control system:
• MobileView Guard G750
• MobileView Machine Terminal MT750
The Junction Box can be used either inside or outside a control cabinet based on its
IP65 rating.
The cables that connect the MobileView terminal to the Junction Box are available
as separate catalog numbers.
• MobileView Connection Cable (Catalog Numbers 2727-MRTxx) connects the
MobileView terminal to the Junction Box. The Connection Cable is available
in 5, 10, 15, 20 meter (16.4, 32.8, 49.2, 65.6 foot) lengths.
• MobileView Junction Box Cable (2727-MREY1) connects the Junction Box to
the MobileView Connection Cable when the Junction Box is mounted inside
a cabinet. The cable is 2 meters (6.56 feet) long.

The Junction Box and the MobileView terminal meet the safety
class III in accordance with EN 61131-2 and EN 50178. When
connecting the MobileView terminal, make sure all voltages
connected to the terminal are safety low voltages and isolated
from the low voltage supply system by a safety transformer or
a similar safety component.

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).
The power supply circuit must be protected by a 3.5A fuse.
The nominal supply voltage of the MobileView terminal
without the connection cable is 24V dc (supply voltage range:
18 -32V dc.
When planning the power supply, consider the voltage drop
in the connection cable. Specifications of the power supply
lines in the cable are:
• Cross section: AWG24 (0.24mm2)
• Material: zinc-coated copper strand
• Line resistance: <90 Ohm/km (<145 Ohm/mile)
