Precautions When Wiring - Omron E5EC-T Datasheet

E5EC-T/E5AC-T
● Precautions when Wiring
• Separate input leads and power lines in order to prevent external
noise.
• Use a shielded, AWG24 to AWG18 (cross-sectional area of 0.205
2
to 0.8231 mm ) twisted-pair cable. Use a shielded, AWG24 to
AWG14 (cross-sectional area of 0.205 to 2.081 mm
cable for the E5CC-U. The stripping length is 6 to 8 mm for the
E5CC, E5EC, E5AC, E5DC, or E5CC-T and 5 to 6 mm for the
E5CC-U.
The E5GC stripping length is 6 to 8 mm for models with screw
terminal blocks and 8 to 12 mm for models with screwless clamp
terminal blocks.
• Use crimp terminals when wiring the terminals.
• Use the suitable wiring material and crimp tools for crimp terminals.
• Tighten the terminal screws to a torque of 0.43 to 0.58 N·m.
The specified torque is 0.5 N·m for the E5CC-U.
• For the E5GC, E5CC, E5EC, E5AC, E5DC, or E5@C-T, use the
following types of crimp terminals for M3 screws.
• For the E5CC-U, use the following types of crimp terminals for
M3.5 screws.
Three-year Guarantee
● Period of Guarantee
The guarantee period of the Unit is three years starting from the date
the Unit is shipped from the factory.
Scope of Guarantee
The Unit is guaranteed under the
following operating conditions.
1. Average Operating Temperature
(see note): −10°C to 50°C
2. Mounting Method: Standard mounting
Note: Average Operating Temperature
Refer to the process temperature
of the Unit mounted to a control
panel and connected to peripheral
devices on condition that the Unit
is in stable operation, sensor input
type K is selected for the Unit, the
positive and negative thermocouple input terminals of the Unit
are short-circuited, and the ambient temperature is stable.
Should the Unit malfunction during the guarantee period, OMRON
shall repair the Unit or replace any parts of the Unit at the expense of
OMRON.

• For E5GC Controllers with screwless clamp terminal blocks, use
braided or solid wires with a gauge of AWG24 to AWG18 (equal to
a cross-sectional area of 0.205 to 0.823 mm
The length of the conductive portion inserted into the terminal must
be 8 to 12 mm. Ferrules must be 0.8 to 1.4 mm in diameter..
