Connecting The Device - Siemens SITRANS P500 HART Compact Operating Instructions

WARNING
Incorrect selection of type of protection
Danger of explosion in areas subject to explosion hazard.
This device is approved for several types of protection.
1. Decide in favor of one type of protection.
2. Connect the device in accordance with the selected type of protection.
3. In order to avoid incorrect use at a later point, make the types of protection that are not used permanently
unrecognizable on the nameplate.
NOTICE
Ambient temperature too high
Damage to cable sheath.
At an ambient temperature ≥ 60 °C (140 °F), use heat-resistant cables suitable for an ambient temperature at least 20
•
°C (68 °F) higher.
NOTICE
Incorrect measured values with incorrect grounding
The device must not be grounded via the "+" connection. It may otherwise malfunction and be permanently damaged.
If necessary, ground the device using the "-" connection.
•
Note
Electromagnetic compatibility (EMC)
You can use this device in industrial environments, households and small businesses.
For metal housings there is an increased electromagnetic compatibility compared to high-frequency radiation. This
protection can be increased by grounding the housing, see Chapter "Connecting the device (Page 16)".
Note
Improvement of interference immunity
Lay signal cables separate from cables with voltages > 60 V.
•
Use cables with twisted wires.
•
Keep device and cables in distance to strong electromagnetic fields.
•
Use shielded cables to guarantee the full specification according to HART.
•
Refer to HART communication information in Chapter "Technical data (Page 27)".

Connecting the device

Opening the device
1. Unscrew the cover of the electrical cable compartment. An identification text "FIELD TERMINALS" is provided at the side
of the housing.
Connecting the device
1. Insert the connecting cable through the cable gland
2. Connect the device to the system with the protective conductor connection
3. Connect the wires to the connecting terminals
Observe the polarity when doing this. If necessary, ground the device using the "-" connection by connecting the
"-" connection to the ground terminal
