Endress+Hauser WirelessHART Fieldgate SWG70 - Connecting to Power Supply and Grounding

WirelessHART Fieldgate SWG70 Electrical Installation
Endress + Hauser 23
5.2 Connecting to power supply and grounding
There are two 24 VDC power supply terminal blocks located inside Fieldgate SWG70, allow-
ing for redundant power supply. Open the housing cover to access the terminal blocks.
NOTICE!
• Ensure adequate strain relief for the cables.
• Pay attention to the bending radii of the cables. Do not drop below the permitted bending
radii.

Connecting to 24 VDC
power supply and
grounding
Fieldgate SWG70 must be connected to a 24 VDC power supply. For details, see the
Technical Information for "WirelessHART Fieldgate SWG70" (TI00027S) on the CD-ROM
provided.
DANGER!
Risk of electric shock if the wrong power unit is used.
• Always use a SELV/PELV power unit to guarantee electrical safety.
1. Switch off the power supply.
2. Connect the protective ground to one of the two ground terminals.
3. Unscrew the 4 screws of the housing cover and remove the housing cover. See
Figure 4-5 on page 21.
4. Route the 24 VDC power cable through the second cable gland from right.
The permissible cable diameter lies between 6 mm and 10 mm.
5. Connect the 24 VDC power cable to the first power supply connection "Line 1" observing
polarity. See Figure 5-1 on page 22.
6. If you want to connect a redundant power supply (optional), route the second 24 VDC
power cable through the cable gland on the far right of the housing.
7. Connect the second power cable to the second power supply connection "Line 2"
observing polarity.
