E5@C Digital Temperature Controllers User’s Manual (H174)
Preparations for Use
Be sure to thoroughly read and understand the manual provided with the product, and check the follow-
ing points.
*1 The specified torque is 0.5 N·m for the E5CC-U.
*2 When two or more E5GC Digital Controllers are mounted, make sure that the ambient temperature of the
Digital Controller does not exceed the allowable operating temperature range given below.
Horizontal group mounting: −10 to 55°C
Vertical group mounting of two Digital Controllers: −10 to 45°C
Vertical group mounting of three or more Digital Controllers: −10 to 40°C
For vertical group mounting, use Digital Controllers with screwless clamp terminal blocks.
For E5EC models with two control outputs (QQ, QR, CQ, RR, CC, or PR) and 011, 012, 013, or 014 options,
the ambient temperature for group mounting must be 45°C max.

Purchasing
the product
Product
appearance
After purchase, check that the product and packaging are not dented or
otherwise damaged. Damaged internal parts may prevent optimum control.
Product model and
specifications
Make sure that the purchased product meets the required specifications.
Setting the
Unit
Product installation
location
Provide sufficient space around the product for heat dissipation. Do not
block the vents on the product.
Wiring Terminal wiring Do not subject the terminal screws to excessive stress (force) when
tightening them.
Make sure that there are no loose screws after tightening terminal screws to
the specified torque of 0.43 to 0.58 N·m.
*1
Be sure to confirm the polarity for each terminal before wiring the terminal
block and connectors.
For the E5@C-B (models with Push-In Plus terminal blocks), do not attempt
to wire anything to the release holes.
For the E5CC-B or E5DC-B (models with Push-In Plus terminal blocks), use
crossover wiring only for the input power supply and communications. Do
not exceed the maximum number of Digital Controllers given below if you
use crossover wiring for the input power supply.
100 to 240 VAC Controllers: 16 max.
24 VAC/VDC Controllers: 8 max.
Do not perform crossover wiring for the E5DC-B (models with Push-in Plus
Terminal Blocks).
Power supply
inputs
Wire the power supply inputs correctly. Incorrect wiring will result in
damage to the internal circuits.
Operating
environment
Ambient
temperature
The ambient operating temperature for the Digital Controller is −10 to
55°C
*2
(with no condensation or icing).
To extend the service life of the product, install it in a location with an
ambient temperature as low as possible. In locations exposed to high
temperatures, if necessary, cool the products using a fan or other cooling
method.
Vibration and
shock
Check whether the standards related to shock and vibration are satisfied at
the installation environment. (Install the product in locations where the
contactors will not be subject to vibration or shock.)
Foreign particles Install the product in a location that is not subject to liquid or foreign
particles entering the product.
