2. Установка и подключение
Installation and connection
Установка
Место крепления устройства должно быть защищено от попадания механических объектов (пыли, грязи, крупных объектов) и воды.
Место крепления должно предполагать удобный доступ к устройству для подключения других элементов батарейной системы: батарейных модулей, термисторов, контакторов.
Габаритные и установочные размеры BMS Main X приведены ниже.
