Here are some photos of my battery backup system to power my two Tunze Streams (6105) using the Tunze Safety Connectors and also power my Neptune Systems Apex controller.
It's acutually a very simple setup. I use a 35 Amp Hour car battery with simple automotive trailerhitch wiring connectors. I could have hardwired the Tunze Safety Connectors and the Apex 12V power supply leads directly to the terminal posts of the battery, but I wanted a simple and reliable way to disconnect the battery or individual components.
Photo 1: So I selected these simple pos/neg SAE type tailerhitch connectors and connected one to each pair of leads from the Tunze Safety Connectors and one to the Apex 12V power supply plug.
Photo 2: Next I purchased 3 TechMate SAE-71 connectors to attach to the terminal posts of the battery. And the CTEK battery charger came with it's own pigtail to attach to the battery terminal posts. The second photo is of these TechMate SAE and CTEK pigtails.
Photo 3: I was also pleased to see that each of these pigtails included an inline automotive type fuse and eyelets on each of the leads. As can be seen in the third photo.
Photo 4: And finally I purchased a simple plastic automotive battery case to protect me and any equipment from the exposed battery terminal posts.
Photo 5: This is the CTEK battery charger that I use to maintain the battery.
I purchased the Tunze Safety Connectors, the CTEK battery charger and the TechMate SAE-71 connectors online and all of the other items at my local automotive supply. I did not include a photo of the Tunze Safety Connectors, but they come with pos / neg battery leads that I simply crimp connected to the SAE type trailerhitch connectors shown in Photo 1.
Hope this helps...:hmm1:
