Lynx Smart BMS 5. Installation 5.1. Important warning Lithium batteries are expensive and can be damaged due to over discharge or over charge. The shutdown due to low cell voltage by the BMS should always be used as a last resort to be on the safe side at all times. We recommend not letting it get that far in the first place and instead either shutting down the system automatically after a defined state of charge (this can be done by using the Discharge floor setting [17] in the BMS) so that there is always enough reserve capacity in the battery, or to use the remote on/off function [12] of the BMS as a system on/off switch. Damage due to over discharge can occur if small loads (such as:
alarm systems, relays, standby current of certain loads, back current drain of battery chargers or charge regulators) slowly discharge the battery when the system is not in use. In case of any doubt about possible residual current draw, isolate the battery by opening the battery switch, pulling the battery fuse(s) or disconnecting the battery plus when the system is not in use. A residual discharge current is especially dangerous if the system has been discharged completely and a low cell voltage shutdown has occurred. After shutdown due to low cell voltage, a capacity reserve of approximately 1Ah per 100Ah battery capacity is left in the battery.
The battery will be damaged if the remaining capacity reserve is drawn from the battery, for example, a residual current of just 10mA can damage a 200Ah battery if the system is left discharged for more than 8 days. Immediate action (recharge the battery) is required if a low cell voltage disconnect has occurred. 5.2. Safety Precautions 5.2.1. Safety Warnings Lynx Distribution System Installation must strictly follow the national safety regulations in compliance with the enclosure, installation, creepage, clearance, casualty, markings and segregation requirements of the end-use application. Installation must be performed by qualified and trained installers only. Do not work on live busbars.
Ensure that the busbar is unpowered by disconnecting all positive battery poles prior to removing the Lynx front cover. Work on batteries should be carried out by qualified personnel only. Observe the battery safety warnings as listed in the battery manual. Store this product in a dry environment. The storage temperature should be -40°C to +65°C. No liability can be accepted for damage in transit, if the equipment is not transported in its original packaging. Page 7 Installation
