■External Connection
Terminal Block Connections
Thermocouple
A thermocouple has polarity. Connect thermocouples to the terminal
block correctly using compensating conductor that are suitable for
the thermocouples.
Be sure to use the cold junction compensator (no. 13 and 15) pro-
vided with the E5ZE. The lot and serial numbers of the cold junction
compensator must be identical to those of the E5ZE. Do not touch
the cold junction compensator while operating the E5ZE.
The number of each of the above thermocouples is a point number.
Platinum Resistance Thermometer
Make sure there in no difference in resistance among the three con-
ductor of each platinum resistance thermometer used with the E5ZE.
Do not short-circuit terminals 7, 8, 20, and 21.
The number of each of the above platinum resistance thermometer is
a point number.

■Wiring for Conformance to the EMC Directives
Conformance of the E5ZE to the EMC Directives has been confirmed according to the following conditions.
Note: 1. Place the power supply, filter, input sensor, I/O terminals, and communications cable inside the control panel when wiring them.
2. If the communications cable between devices extends outside the control panel, satisfy the following conditions when wiring them.
•Use shielded cables for communications cables and ground to the FG.
•Insert at least five ferrite cores close to the E5ZE.

Installation
■I/O Units
I/O Units are not mounted on the E5ZE.
Mount the appropriate I/O Units according to the specification of the E5ZE.
The diagram below is the view from the back of component side.
Type of I/O Units
Tighten the screws through the holes marked with a black dot (●) to the fixing studs of the E5ZE.

Mounting the Units
Use appropriate Phillips screwdriver for the screws. Use of aninappropriate screwdriver may damage the screws and cause insufficient tightening.
Mount the Units in an environment where anti-static electricity countermeasures have been taken.
Store the removed screws carefully and use them again when required.
Model With Casing
1. Remove the connector fixing screws (2 screws each for a connec-
tor) from the Units (except for communication unit).
2. Remove the casing fixing screws (6 screws).
3. Remove the casing.
4. Mount the Units in the same manner as the model without casing.
5. Fix the connector to the case using the connector fixing screws
with a torque of 0.34 to 0.39 N·m.
6. Replace the casing in its original position using six casing fixing
screws.
Model Without Casing
1. Remove the Unit fixing screws.
When CT Input Unit is not required, do not touch the correspond-
ing screws. To prevent the studs from loosening, use a wrench to
fix the studs.
2. Fix the Units in the designated position.
Connect the Units and the E5ZE connector properly.
3. Fix the Units to the studs with fixing screws with a torque of 0.43
to 0.58 N·m.

■Mounting the Controllers
E5ZE-8@AAM@B-E (Casing Type)
Side-by-side, Close Mounting
Saves space and improves wiring efficiency.
Wall Mounting
Can be mounted to places with limited depth.
Precautions
■Correct Use
!WARNING
A lithium battery is used in the Temperature Controller.
Do not take the Temperature Controller apart or allow it to be de-
formed under pressure, heated to 100°C or higher, or incinerated.
The battery may ignite or erupt.
■General Mounting Precautions
E5ZE-8@AAM@B-E (Casing Type)
The side of the E5ZE with the terminal block and connectors must
not face up, otherwise operating errors may result.
Prepare four M4 screws to mount the E5ZE to control panels. Use
flat washers and spring washers with screws to mount the E5ZE to
control panels so that the screws will not loosen.
The mounting brackets must be attached to the E5ZE with the four
M3 x 6 screws provided with the E5ZE and each of the screws
should be tightened to a torque of 0.43 to 0.58 N·m, or 4.4 to
5.9 kgf·cm.
E5ZE-8@AAM@-E (Open Type)
The side of the E5ZE with the terminal block and connectors must
not face up, otherwise operating errors may result.
Use flat washers and spring washers with screws to mount the E5ZE
to control panels so that the screws will not loosen.
Each of the screws should be tightened to a torque of 0.43 to
0.58 N·m, or 4.4 to 5.9 kgf·cm.
Do not use any mounting stud or screw other than the ones provided
with the E5ZE.
If the stud screws are loose, tighten each of them to a torque of 0.43
to 0.58 N·m, or 4.4 to 5.9 kgf·cm.
