Precautions
Mounting
The dimensions of the Temperature Controller conform to DIN
43700. Recommended panel thickness is 1 to 8 mm.
Do not install the Temperature Controller in a location exposed to
excessive dust or corrosive gases. Moreover, avoid locations sub-
ject to heavy vibration or shock, water or oil spray, or high tempera-
tures. Any of these condition will affect product life.
Isolate the Temperature Controller from equipment that generates
strong, high-frequency noises such as high-frequency welders, be-
cause such equipment may prevent proper operation.
Attach the two mounting brackets supplied with E5AX on the top
and bottom of the Temperature Controller. Tighten the screws of the
mounting brackets with your fingers.

Connection Examples

With Solderless Terminal
Use M3.5 solderless terminals with the Temperature Controller's
M3.5 self-rising pressure plate screws.
Solder-dipped Leads
Strip 6 to 12 mm of the lead wires and carefully arrange the wire tips.
Do not tighten the terminal screw with excessive force, because do-
ing so may damage them. The terminal block of the Temperature
Controller is constructed so that the lead wires can be connected to
all the terminals from the same direction.

Input Connection

To reduce inductive noise influence, the lead wires connecting the
input to the Temperature Controller must be separated from the
power lines and load lines.
Use the specified compensating conductors for thermocouples.
When using a thermocouple as the temperature sensor, attach the
short-circuit bar shown in the terminal block diagram on the hous-
ing. Use lead wires having a small resistance for temperature resis-
tance thermometers.
Be sure to remove the short-circuit bar from the terminals when a
temperature resistance thermometer is used.
Sequenced Circuits
Several seconds are required until the relay in turned ON after pow-
er has been supplied to the Temperature Controller. Therefore, take
this time delay into consideration when designing sequenced cir-
cuits which incorporate a Temperature Controller.
Stickers Inside Frontcover
Stickers indicating the temperature sensor type (R, S, K, J, T, E, L,
and U) are supplied with the Temperature Controller. Attach the
proper stickers to the front panel as shown below.
