Surge protection for industrial connectors
HARTING's new Han-Modular Surge Protection Modules make it possible to move surge protection into its most widely used industrial connector series, a space-saving idea that simpli es wiring arrangements. Proper surge protection for Instrumental and Control (I&C) signals usually requires separate, external solutions that add to material and labor costs. When used correctly, the new surge protection (SP) modules will reduce the number of operating faults, increase the service life of the production line, and ultimately increase production uptime for better plant operating performance. ere are two types of SP module: a two-channel version for di erential signals and four-channel type
for signals with common reference potential. Each can transmit nominal 24Vdc and up to 0.5A. e protection level is approximately 50V depending on the type. Transient energy, which can disturb signal circuits and destroy electronic devices, is discharged to the ground via an appropriate spring element and the grounded Han-Modular Hinged Frame. is ensures interference-free transmission of the signal.

Detergent, or any other product that is added to the water in a panel cleaning system, should meet the following requirements:
1. It must be compatible with the solar panel lms, aluminum rails, racking, and epoxy.
2. It should be approved by the solar panel manufacturer.
3. It must be biodegradable with low environmental impact, and contain no VOCs.
4. It should have low toxicity for worker safety.
5. It should be speci cally formulated to remove contaminants commonly found on panels.
6. It should rinse o thoroughly, with no spotting or residue.
7. It should be dilutable in water, and suitable for use with either tap or deionized water.
8. It should dissolve and remove dirt, jet fuel residue, and
dust o of panels, o ering hydroscopic action to achieve this performance enhancement.
If you follow these guidelines for cleaning and maintaining your solar arrays, you will ensure that your system operates at its highest level, at maximum output, and with the longest possible equipment life and ROI.
