REGULATIONS FOR SAFE INSTALLATION • For electrical work, follow the local national wiring standards, regulations and these installation instructions. • Install the product in a heatproof environment. Ensure therefore that there are no chemicals, plastic parts, curtains or other textiles, etc. in the immediate vicinity of the equipment. • It is normal for the Scotty AI 1500 to get hot during operation. Keep any objects that are heat-sensitive away.

• Never install or use the product at sites where gas or dust explosions could occur. • Use flexible multi-stranded copper cables for the connections (UL: Class I; IEC: Class 5).

• The installation must include a fuse in accordance with the recommendations in the table Cable type recommendations. • Always remove all dirt and paint from chassis connection points. Apply the correct torque when fastening the connection bolts.

The alternator temperature sensor is essential for the operation of the Scotty Al. Attach the alternator housing as close as possible to the regulator, but not on it.

Connect Harness Wiring in this order: 1. Connect Alternator Temp (black) to Scotty AI ground. Connect the alternator Temp. (red) to the Alt Temp positive wire in the wiring harness. Connect the alternator voltage sensor wire (fuse at 3 A) JVSQXLIEPXIVREXSV to the Alt + wire in the wiring harness.

INSTALLATION Have your High Side 24 V or 48 V (HS) batterie connected and the isolator applied so there is no power connection. Connect the 12 V Low Side and the ‘Enable Wire to 12 V Side’. A green flashing LED starts flashing. No Power will flow as no 24 V or 48 V battery is connected to HS. Open phone/tablet/laptop to WiFi > scan> connect to ‘Scotty XXXX’ SSID. The initial password is IMXLIV 12345678 SVSRRI[IVZIVWMSRW7GSXX]EM$ GETMXEP7 . You can change the password later. Once connected, the ‘wheel connection indicator may still be turning’ as there is no internet. Go to the browser (we use Chrome) and type in: 172.24.24.1. Save this page to your home screen for future easy use. Check the values on the status page. You are ready to go. Just turn on the 24 V or 48 V battery on the HS to operate. Apply a voltage greater than 13 V and up to 125 A of current to the Low Side (LS), which will then charge a 24 V or 48 V battery on the High Side as a maximum of 60 A for a 24 V battery at 28 V, or 30 A for 48 V battery at 52 V. OPERATION • ‘Soft’ puts the lowest load on the 12V Power Supply. • Turn Scotty AI ‘Off’ and select ‘Soft’ for the lowest load setting. • Go to ‘Medium’ for first-time users who are unsure. • Go to ‘Hard’ to drive the maximum power from Low Side.
