6 Electrical connection
6.1 Connecting requirements
6.1.1 Power supply
Connect a regulated class 2 DC power source to the gateway. The supply voltage can be from
10.8 to 30 V
DC
, with a recommended nominal voltage of either 12 V
DC
or 24 V
DC
. The power
supply must be able to supply 290 mA current at 24 V
DC
. External connecting cables must be
used in accordance with NEC, ANSI/NFPA70 (for US applications) and Canadian Electrical
Code, Part 1, CSA C22.1 (for Canadian applications) or in accordance with local country codes
for all other countries.
The control cabinet or switch box must meet the specifications of EN 60950-1: 2001 for fire
enclosures.
The power supply to the device must meet the following requirements:
• Class 2 circuit in accordance with National Electrical Code, NFPA-70 and Canadian
Electrical
• Limited Power Supply (LPS) as per EN/IEC 60950-1 or EN/IEC 62368-1
• Limited-energy circuits EN/IEC 61010-1
6.1.2 Ethernet
The FieldGate SWG50 has an Ethernet interface (RJ45) on the front for connecting a twisted-
pair cable with an impedance of 100 Ω. Data transmission is 10, 100 or 1 000 Mbit/s. Slide
the Ethernet cable with the RJ45 connector into the device until it locks into place. When two,
three or four Ethernet ports are used, the FieldGate SWG50 is classified as a switch. If only
one port is used, it is a straightforward end-node device. The maximum number of linked
gateways and the maximum distance between the units are based on the Ethernet standards
and are determined by the environment and the compliance of the network with the standard.
