Siemens Building Technologies CE2M5324xx 15.05.2015 12
Terminals
2-pole or 4-pole terminals are used for connection of the ex-
ternal cables to the modules.
 Strip-back length 5 mm
 Connection capacity
 rigid or flexible, 0,2 … 2,5 mm²
 flexible with wire end ferrule, 0,25 … 1,5 mm²
 conductor sizes 26 … 14 AWG
 Multiple conductor connector (2 conductors with the same
cross-section)
 rigid or flexible, 0,2 … 0,75 mm²
 flexible with wire end ferrule without plastic sleeve,
0,25 … 0,34 mm²
 flexible with TWIN wire end ferrule with plastic sleeve,
0,5 … 0,75 mm²
 Recommended screwdriver:
 0,6 × 3,5 mm
 Tightening torque: 0,4 Nm
3.5 Non-detachable temperature sensors
Note: Wires must not be separated, shortened or
extended in factory-set, non-detachable temperature
sensors.
 Insert the temperature sensors into the pockets, ball-valves
or T-pieces.
 Seal the temperature sensors to protect against manipula-
tion.
3.6 Detachable temperature sensors
Note: If detachable temperature sensors are used
they must have their own calibration or certification of
conformity.
Note: The maximum cable length of the temperature
sensors is 10 m. Extension is not permitted.
 Press the 4 side lugs of the housing cover inwards and
remove the cover.
 Guide the wire of the temperature sensor from the outside
through the 2nd sleeve from the left and the return sensor
through the 3rd sleeve from the left.
 Strip both wires as in the figure 12.

 Connect the cores in line with the inscription printed on the
meter.
The 2-wire connection occurs on terminal 5/6 and 7/8. This
also applies to 4-wire connection).
Note: Do not connect the shielding braid on the meter
side.
 Insert the temperature sensors into the pockets, ball-valves
or T-pieces.
 Seal the temperature sensors to protect against manipula-
tion.
When the LCD display shows , you can reset
this error message via the parameterisation menu, as de-
scribed in chapter 4.4 „Call up parameter operation“.
 Put the housing cover in position gently and press it gently
until all the lugs click into place audibly.
