Grouding; Grounding The Got - Mitsubishi Electric GOT1000 General Description Manual

POINT
(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
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
equipped at the lower-left corner on the GOT main unit back
face.(Refer to the previous page.)
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
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.

6.4.1 Grounding the GOT

About grounding
Perform the following three items for grounding.
• Independent grounding should be performed as possible for
the GOT.
Perform grounding works. (grounding resistance 100
less)
• When independent grounding cannot be performed for the
GOT, perform "(2) Shared grounding" shown below.
