Additional Installation Tips 7 Additional Installation Tips When experiencing communication problems in for example noisy environments or when operating close to temperature limits, the following recommendations are to be noticed. 7.
Additional Installation Tips 7.2 Ethernet Connection in the Panel PC Industrial Ethernet RJ45 RJ45 1 RJ45 RJ45 Panel PC RJ45 3 2 Panel PC RJ45 4 Shielded 1-1 2-2 3-3 Short and unshielded Panel PC RJ45 8-8 5 Panel PC RJ45 0.1 uF 250 V 5351 In some industrial units for Ethernet, the RJ45 contact’s shield is connected to the chassis via a capacitor, see 1 in drawing above. The Panel PC’s Ethernet shield is directly connected to the chassis, see 2 in drawing above. 1.
Additional Installation Tips 7.3 • • • • • • • • To Achieve Better EMC Protection Initially, use the original cabling from Beijer Electronics primarily. Use shielded cables for RS232 communication. Use twisted pair and shielded cabling for RS422 and RS485. Use the cabling intended for the bus type; Ethernet, Profibus, CC-Link, CAN, Device Net etc. Install and connect according to applicable specifications for the relevant bus standard.
Additional Installation Tips 7.4 Ambient Temperature The maximum ambient temperature for the Panel PC is provided in the specifications. The ambient temperature refers to the temperature in the device cabinet which cools the Panel PC’s electronics.
Additional Installation Tips 7.5 Safety Most of the Panel PCs are fed with 24 V DC.

See 1 in drawing above.
Additional Installation Tips 7.6 Galvanic Isolation Internal electronic Filter Ethernet DC/DC galvanic isolation DC/AC VCC +24 V DC CFL 0 V (GND) 0V 1.5 m RS422/485 RS232 USB 5356 USB The Panel PC has galvanic isolation against the 24 V DC feed but no galvanic isolation between the communication ports for RS232, RS422/485 and USB. Only the Ethernet connection has galvanic isolation.
Additional Installation Tips 7.7 Cable and Bus Termination RS485 Use shielded and twisted pair cable. The pair capacitance may not exceed 52.5 pF/m and area at least 0.25 mm2 (AWG 24), if you want to use the maximum transfer distance and maximum transfer speed. 0 V, the reference voltage for communication should be included in the cabling. With two-way communication use two pairs; one pair for communication and one pair for 0 V. The shield must be grounded at one end.
