(3) Please connect a shielded cable and a hermetically sealed cable with the ground
separately.
(4) Terminals with insulation sleeves can not be arranged as a terminal block. It is
recommended that the terminals be covered with insulation tubes.
(5) The diameters of the input/output cables used should be in the range of 30 AWG to 24 AWG
(0.3 mm to 0.6 mm). The lengths of the plastic jackets removed should be in the range of 7
mm to 8 mm. The specifications for the terminals on AH08PTG-5A and the wiring of the
terminals are shown below. The temperature of the copper lead wires used should be
60/75°C.
