Electrical Requirements
WARNING: The DC power source providing power to the MTS must be compliant with
requirements specified for a safety extra low voltage circuit (SELV) per EN60950.
WARNING: Any device (that is power supply) providing isolation between the AC mains and the
MTS must provide reinforced insulation to hazardous voltages.
CAUTION: All electrical wiring for the MTS site must meet the requirements of all applicable
local codes and regulations.
CAUTION: The battery installation needs a short circuit protection closest to the batteries.
Install the batteries in the same building and provide proper ventilation.
