The RTD cable connecting port is covered with a cap
to keep out dust. The cap should not be removed until
you are ready to install the cable.
• Components for the cable gland
The cable gland assembly consists of an entry, seal,
running coupler, and backnut. Confirm that the seal is
attached inside the entry and that the thread size of the
cable gland is the same as that for the RTD electrical
connection.

CAUTION
Input/output signal is non-isolated.
Do not turn on power supply until you complete
all the wiring work.
Procedure
(1) Disassemble the cable gland: loosen the
running coupler to separate the backnut from
the entry.
(2) Remove the protection cap over the transmitter
electrical connection and install the entry on
the electrical connection. Note that a non-
hardening sealant should be applied to the
threads for a 1/2 NPT connection and a gasket
should be used for an M20 connection.
(3) Pass the RTD cable through the running
coupler and backnut assembly.
(4) Remove the cap from the connecting port.
Then insert the RTD cable and firmly plug its
connector into the connecting port in the
transmitter's terminal box.
(5) Align the running coupler on the entry.
