Remark
(1) For installations where there is voltage drop, it is recommended to use stranded wire with a cross sectional
area greater than 2
㎟
.
(2) It is recommended that cable connections are twisted and secure. Short cable runs are also recommended
between the point of supply and the XGT panel.
(3) For safety reasons it is recommended that you use color coded outer sheaths on the conductors to aid safe
terminations.
Wiring of power is as follows.
[DC Power connection]
Remark
(1) Use a regulated power supply transformer when the power fluctuation is bigger than the standard.
(2) If electromagnetic interference is experienced or expected use an insulation transformer to protect the
XGT panel from interference.
(3) All field-wiring connections to this unit shall be from Limited Voltage/Limited Current, below 24V dc
isolated secondary source, Class 2 secondary circuits or SELV/PELV circuits.
