Atmosphere; Electrical Environment - Omron NYP25-*-11 SERIES User Manual

is designed so that malfunctioning will not occur within the specifications for vibration and shock. If,
however, the Panel PC is to be used in a location in which it will be directly subjected to regular vibra-
tion or shock, then implement the following countermeasures:
• Separate the Panel PC control panel from the source of the vibration or shock. Or secure the Panel
PC and the control panel with rubber padding to prevent vibration.
• Make the building or the floor vibration-resistant.
• Prevent shocks when other devices in the panel, such as electromagnetic contactors, operate. Se-
cure either the source of the shock or the Panel PC with rubber padding.

Atmosphere

Using the Panel PC in any of the following locations can cause defective contact with connectors and
corrosion of components. Implement countermeasures such as purging the air as required.
• In locations exposed to dust, dirt, salt, metal powder, soot, or organic solvents, use a panel with an
airtight structure. Be careful of temperature increases inside the panel.
• In locations exposed to corrosive gas, purge the air inside the panel to clear the gas and then pres-
surize the inside of the panel to prevent gas from entering from outside.
• In locations where flammable gas is present, either use an explosion-protected construction or do
not use the Panel PC.

Electrical Environment

When installing or wiring devices, make sure that there will be no danger to people and that noise will
not interfere with electrical signals.
Installation Location
Install the Panel PC as far away as possible from high-voltage (600 V or higher) and power devices to
ensure safe operation and maintenance.
