Power Interface
The device is getting power through a 3-way terminal block socket/plug,
which the 3
rd
pin
(“E”)
is for protective earth connection and can be left
floating if not used. The power source must be within the ratings specified in
the product hardware manual, otherwise damage to the internal
electronics, as well as customer equipment, could happen. It is
recommended to use the 12VDC/1.5A power adaptor available from RFI,
which can be ordered as an optional accessory.
Power Interface
The device is protected against reverse-polarity voltage input and will not
be powered. However, please do NOT keep device supplied with improper
power source for an extended period.
Always take extra cautions when trying to connect the protective earth, as
different potential may exist in the electric wiring system and improper earth
connection can cause loop current and risk of equipment damage. It is
recommended to carry out a thorough review of the relevant electrical
circuit/wiring in advance.
