LCAUTION
‣Switch off the power supply before installing or connecting the device. Non-compliance
may result in the destruction of parts of the electronics.
‣When connecting Ex-certified devices, please take special note of the instructions and
connection schematics in the Ex-specific supplement to these Operating Instructions.
‣Do not occupy the display connection. An incorrect connection can destroy the electronics.
‣Before connecting the power supply, connect the potential equalization line to the external
ground terminal.
‣The device may only be powered by a power unit with an energy-limited circuit in
accordance with UL/EN/IEC 61010-1, Section 9.4 and the requirements of Table 18.

‣ ESD - Electrostatic discharge. Protect the terminals from electrostatic discharge. Non-
compliance may result in the destruction or malfunction of parts of the electronics.
5.2.1 Fieldbus connection
Devices can be connected to the fieldbus in two ways:

iTEMP TMT86 Electrical connection
Endress+Hauser 11
• via conventional cable gland →  11
• via fieldbus device connector (optional, available as an accessory)
Risk of damage
• Switch off the power supply before installing or connecting the head transmitter. Non-
compliance may result in the destruction of parts of the electronics.
• Grounding via one of the grounding screws (terminal head, field housing) is
recommended.
• If the shielding of the fieldbus cable is grounded at more than one point in systems
without additional potential equalization, mains-frequency equalizing currents may
occur and cause damage to the cable or shielding. In such cases, the shielding of the
fieldbus cable should be grounded on one side only, i.e. it must not be connected to the
ground terminal of the housing (terminal head, field housing). The shield that is not
connected should be insulated!
• We recommend that the fieldbus not be looped using conventional cable glands. If you
replace even just one measuring device at a later date, the bus communication will
have to be interrupted.

5.2.2 Supply voltage
Connecting to an APL field switch
The device must be used in accordance with the APL port classification:
Hazardous areas: SLAA or SLAC (details in Ex safety instructions)
Non-hazardous areas: SLAX connection to an APL field switch with maximum voltage of 15
VDC and minimal output power of 0.54 W. This corresponds to an APL field switch with APL
port classification SPCC or SPAA, for example.
Connecting to an SPE switch
In non-hazardous areas, the device can be used in accordance with PoDL power class 10: The
device can be connected to an SPE switch with a maximum voltage of 30 VDC and a minimum
output power of 1.85 W. This corresponds to an SPE switch that supports PoDL power classes
10, 11 or 12, for example.
Ethernet-APL power class A (9.6 to 15 VDC, 540 mW)
Maximum power consumption: 0.7 W
The field switch must be tested to ensure that it meets safety requirements (e.g. PELV,
SELV, Class 2).
5.3 Connecting the sensor cables
Terminal assignment of sensor connections

iTEMP TMT86 Electrical connection
Endress+Hauser 13
NOTICE
When connecting 2 sensors ensure that there is no galvanic connection between the
sensors (e.g. caused by sensor elements that are not isolated from the thermowell). The
resulting equalizing currents distort the measurements considerably.
‣The sensors must remain galvanically isolated from one another by connecting each sensor
separately to a transmitter. The transmitter provides sufficient galvanic isolation (> 2 kV
AC) between the input and output.

5.4 Ensuring the degree of protection
Compliance with the following points is mandatory following installation in the field or
servicing in order to ensure that IP67 protection is maintained:
• The transmitter must be mounted in a terminal head with the appropriate degree of
protection.
• The housing seals must be clean and undamaged when inserted into their grooves. The
seals must be dried, cleaned or replaced if necessary.
• The connecting cables used must have the specified external diameter (e.g. M20x1.5, cable
diameter 8 to 12 mm).
• Firmly tighten the cable gland. →  6,  15
• The cables must loop down before they enter the cable glands ("water trap"). This means
that any moisture that may form cannot enter the gland. Install the device in such a way
that the cable glands are not facing upwards. →  6,  15
• Replace unused cable glands with dummy plugs.
• Do not remove the grommet from the cable gland.
