4. Installation and Wiring
4.4 Grounding
The optimum method for grounding electronic equipment is to ground it separately
from other high-power systems, and to ground more than one units of electronic
equipment with a single-point ground.
Although the T1-16S has noise immunity to be used in industrial operating conditions,
grounding is important for safety and reliability.
Check the grounding against the following criteria.
1. The T1-16S must not become a path for a ground current. A high-frequency current
is particularly harmful.
2. Equalize the ground potentials when the expansion rack or unit is connected.
Ground the T1-16S and the expansion rack or unit at a single point.
3. Do not connect the ground of the T1-16S to that of high-power systems.
4. Do not use a ground that has unstable impedance, such as painted screws, or
ground subject to vibration.
The grounding marked terminal (see below) is provided on the T1-16S basic unit for
grounding purpose.
In case of the expansion rack is connected to the T1-16S, the rack mounting screw is
used for this purpose.

Mounting panel
• 1.25mm
2
(16 AWG) wire should be used to connect the T1-16S and the expansion
rack/unit with the enclosure grounding bus bar.
• 100Ω or less to ground is required.
!
CAUTION
1. Turn off power before wiring to minimize the risk of electrical shock.
2. Operation without grounding may cause electrical shock or malfunction.
Connect the ground terminal on the T1-16S to the system ground.
