3. Provide adequate ventilation of battery during charging discharging WARNING Refer to battery charger installation insturctions on how to connect and charge batteries WARNING Batteries are electrically alive at all times and must be treated with extreme caution They can supply high short circuit currents even if they appear damaged Take care that dropping or touching of metal objects onto the battery cell does not cause short circuits Remove any personal metal adornment such as a chain watch or ring which could cause short circuits and personal injury READ THIS FIRST BEFORE INSTALLING THE BMS 001 CAREFULLY READ THE FOLLOWING INSTRUCTIONS ESPECIALLY THE SAFETY NOTES AND WARRANTY CONDITIONS Introduction Congratulations on purchasing the Setec BMS 001 The BMS 001 is a high quality Australian made unit that will continuously monitor your battery and act as a fuel gauge to estimate the state of charge and the time left until it is discharged What is supplied 2 Mounting Bracket 1 BMS 001 Battery Monitor 3 Battery Shunt 4 Shunt wire 5 Wiring loom with fuse amp 4 way connector BMS 001 Basics The BMS 001 product is compatible with any 12 V Lead Acid battery including Valve Regulated Lead Acid VRLA Absorbed Glass Mat AGM and Gel batteries as well as the traditional non sealed batteries The BMS 001 is permanently wired in to your 12 V electrical system and continuously monitors the battery
