This terminal must NOT be operated in an environment with
restricted ventilation. There must be at least 25 mm air clearance around any
top or side ventilation holes with a free flow of air around the unit at ALL
times for the installation.
Operating Environment
The equipment must not be operated or stored in extremes of both
temperature and humidity/moisture. (Operating range 5°C to 40°C and up to

Power Supply
The operating voltage range of the power adaptor should cover the
local power supply for proper operation. The power cable, the power outlet

Please never do any connection / disconnection when system is still
powered on. Please always keep the external power adaptor in a free air
circulation.
