NOTE:
1) Do not run input wires with power cables.
2) For TC wiring use proper compensating cable,
preferably shielded (see Thermocouple Compen-
sating Cable Color Codes).
3) Shielded cable should be grounded at one end
only.
NOTE: Any external components (like Zener diodes,
etc.) connected between sensor and input terminals may
cause errors in measurement due to excessive and/or
not balanced line resistance or possible leakage cur-
rents.

NOTE: When a relay output is used to drive an inductive
load, connect an external snubber network (RC) across
the terminals:
in accordance with the following table:
