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.

Storage Temperature -20°C to +70°C (-4°F to +158°F)

Relative Humidity (non-condensing) 5% to 95%

Vibration resistance (operation) 5≤ f < 9 Hz 7mm 9 ≤ f ≤ 150 Hz 2g

Shock Resistance (operation) 15g / 11 ms

Housing

Construction Double-walled ABS housing withstands grease, oil, lubricants, alcohol, etc.

Flammability Class UL 94-V0

Dimensions (W x H x D) 160 mm x 140 mm x 70 mm (6.3 in x 5.5 in x 2.76 in)

NEMA Rating IP65

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)
