Precautions
PRECAUTIONS WHEN WIRING
•
Use wire ducts to separate input leads and power lines in
order to protect the Controller and its lines from external
noise.
•
Solderless terminals are recommended when wiring the Con-
troller.
Power Blocks
The E5AK/E5EK has independent power supplies for each of the terminal blocks shown below.

Option Boards.
OPERATING ENVIRONMENT
•
Keep within the rated ambient operating temperature, ambi-
ent operating humidity, and storage temperature ranges.
•
Use the Unit according to the vibration resistance, shock
resistance, and enclosure ratings.
•
Do not use the Unit in places with corrosive gas or excessive
dust.
•
Do not use the Unit near machines generating high-frequen-
cy noise.
CORRECT USE
Mounting
•
The dimensions of the Digital Controller conform to DIN
43700.
•
Recommended panel thickness is 1 to 8 mm.
•
Mount the Unit horizontally.

Connection
•
To reduce inductive noise influence, the lead wires connect-
ing the input type to the Digital Controller must be separated
from the power lines and load lines.
•
Use the specified compensating conductors for thermocou-
ples. Use lead wires having a small resistance for platinum
resistance thermometers.
Connection Example
•
Wire the terminals of the Unit using solderless terminals.
•
The tightening torque applied to the terminal screws of the
Unit must be approximately 0.78 N
Use the following type of solderless terminals for M3.5 screws.
7.2 mm max.
7.2 mm max.
