Electrical Installation
Note
Avoid running instrument cable next to power cables in cable trays or near heavy electrical
equipment.
It is important that the instrument cable shield be:
- trimmed close and insulated from touching the transmitter housing
- continuously connected throughout the segment
- connected to a good earth ground at the power supply end
4.6 Hazardous areas
When the Rosemount 5400 Series transmitter is installed in a hazardous area, all national and
local regulations and specifications in applicable certificates must be observed.
4.7 External circuit breaker
For compliance with Low Voltage Directive 2006/95/EC, an external circuit breaker should be
installed.
4.7.1 Connecting the transmitter
The Rosemount 5400 Series accepts power supplies ranging from 16 Vdc to 42.4 Vdc. It uses
4-20 mA power superimposed with a HART signal.
To connect the transmitter:
1. Verify that the power supply is disconnected.
2. Remove the terminal block cover (see Figure 4-3).
3. Pull the cable through the cable gland/conduit. For explosion-proof/ flameproof
installations, only use cable glands or conduit entry devices certified explosion-proof or
flameproof. Install the wiring with a drip loop where the bottom of the loop must be
lower than the cable/conduit entry.
4. To connect the wires, see the illustrations on the following pages.
5. Remove the orange protective plastic plugs used for transportation. Seal any unused
port with the enclosed metal plug.
6. Mount the cover and make sure it is fully engaged to meet explosion-proof
requirements (adapters are required if M20 glands are used).
For ATEX, IECEx, NEPSI, INMETRO, and TIIS installations, lock the cover with the locking
screw.
7. Connect the power supply.
Note
Use PTFE tape or other sealant at the NPT threads in the cable entries.
