7.4.3 Strain relief of CS240DM analogue-to-digital module

The CS240DM has an analogue-to-digital, smart-sensor module incorporated that needs to be

secured to the side of PV module. Use two cable tie tabs and cable ties to do this.

This section discusses the following:

8.4 CS240DM and Device Configuration Utility

8.1 Electrical noisy environments

AC power lines, pumps, power inverters, and motors can be the source of electrical noise. If the

CS240 sensor or data logger is located in an electrically noisy environment, the CS240 sensor

should be measured with the 60 or 50 Hz rejection option.

8.2 Long cable lengths

Placement of the cable inside a rugged conduit is advisable for cable runs over 4.5 m (15 ft),

especially in locations subject to digging, mowing, traffic, power tools, animals, or lightning

strikes.

Cable resistance can cause significant error

configuration is the best configuration for long cable lengths.
