Extension Cable Arrangement
It is strongly recommended that only LTH 54E is used to extend the sensor / instrument distance. When
extending the cable a terminal block can be used to connect two lengths of cable.
The user should be careful to avoid wiring the positive drive and return signals into adjacent locations
on the terminal block. The preferred arrangement would be to have the positive signals as far apart
from each other as the terminal block will allow with the negatives between them and the earth
between the negative signals as shown in the following diagram.

The following diagram details the connections required to extend a 54H cable as found on the ECS20
sensors with 54E cable.
