3-1 Installing the PT
3-5
Secure the panel mounting brackets from the back of the panel, as shown in the following
diagram.
Insert the catch on each bracket into the square hole on the PT, and secure the PT to the
panel by tightening the screws with a Phillips screwdriver while gently pulling in the PT.
Precautions
for Safe Use
•
Do not allow metal particles to enter the PT while work is being performed
on the panel.
•
The allowable thickness of the panel for mounting is between 1.6 and 4.8
mm.
Secure the mounting bracket with a uniform tightening torque of between 0.5
and 0.6 N
⋅
m to keep the PT waterproof and dustproof.
The front sheet may become distorted if the tightening torque is more than
the specified limit or not uniform. Always use a panel that is clean, undis-
torted, and strong enough to adequately withstand mounting the PT.
Precautions
for Safe Use
This product conforms to shipbuilding standards. The shipbuilding standards
have conditions that may make them unusable depending on the location in
which the PT is installed. When using a PT on a ship, be sure to contact your
OMRON sales representative.
Shipping Standards (NK, LR, ABS, BV, DNV, KR, GL)
The conditions for use in locations other than the bridge or deck are as follows:
•
The NS-series PT must be installed in a control panel.
•
The control panel must be equipped with an air conditioner.
•
The entire surface of the NS-series PT must be covered with electromag-
netic shielding (specified below) that is also grounded using conductive tape
(e.g., copper tape).
•
Gaps in the door of the control panel must be completely filled or covered
with gaskets or other material.
•
Gaps between the PT and the panel cutout must be completely covered with
conductive tape, such as copper tape, and the PT must be secured using
mounting brackets.
The conditions for use
on a bridge (Class NK certification only)
are as follows:
•
The NS-series PT must be installed in a control panel.
•
The control panel must be equipped with an air conditioner.
•
The entire surface of the NS-series PT must be covered with electromag-
netic shielding that is also grounded using conductive tape (e.g., copper
tape).
•

•
The following noise filter must be connected to the 0 to 24 VDC power line.
Electromagnetic Shielding
* Electromagnetic shielding reduces the permeability by approximately 50%.
