(1) Precautions for wiring to the power supply section
• For 100V AC, 200V AC or 24V DC cable, use the thickest cable as possible
(Max. 2mm
2
) and start twisting them at the position closest to the connected
terminals.
To prevent a short circuit due to loose screws, use the solderless terminal with
insulation sleeve.
• When connection is made between LG and FG terminals, be sure to connect
them to the ground.
Otherwise, the system becomes susceptible to noise.
Since the LG terminal has potential equal to a half of the input voltage, touching
the terminal may lead to an electric shock.
• When grounding the GT155 , ground it with the ground terminal equipped at
the lower-left corner on the GOT main unit back face.
(Refer to the above.)
Connect only the ground cables of the bus connection cable and the CF card
extension unit connection cable to the FG terminal.
(2) Wiring the power section of the GT155 when using an extension unit
Be sure to wire the power section before connecting a cable to the extension unit.
If connecting a cable to the extension unit before wiring the power section, the
terminal block of the power section will be blocked by the cable and the power
section cannot be wired.
