Precautions

Mounting

The dimensions of the Digital Controller conform to DIN 43700.
Recommended panel thickness is 1 to 8 mm.

Do not install the Digital Controller in a location exposed to exces-
sive dust or corrosive gases. Moreover, avoid locations subject to
heavy vibration or shock, water or oil spray, or high temperatures.
Any of these condition will affect product life.

Isolate the Digital Controller from equipment that generates strong,
high-frequency noises such as high-frequency welders, because
such equipment may prevent proper operation.

Attach the two mounting brackets supplied with E5AX on the top
and bottom of the Digital Controller. Tighten the screws of the
mounting brackets with your fingers.

Connection Examples

With Solderless Terminal

Use M3.5 solderless terminals with the Digital 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 Digital Control-
ler 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 Digital Controller must be separated from the power
lines and load lines.

Sequenced Circuits

Several seconds are required until the relay in turned ON after pow-
er has been supplied to the Digital Controller. Therefore, take this
time delay into consideration when designing sequenced circuits
which incorporate a Digital Controller.
