Safety Warnings
Please follow these instructions for personal and operational safety.
WARNING
Assumes that incorrect handling may cause hazardous
conditions, resulting in severe injury or death.
CAUTION
Assumes that incorrect handling may cause hazardous
conditions, resulting in medium or slight injury, or
may cause equipment damage.
WARNING
Don’t use this equipment in a flammable or explosive
environment in order to avoid accidental injury or fire.
You should use external electromechanical devices that are
independent of the PLC (Programmable Logic Controller)
system to provide protection for any part of the system;
otherwise malfunction or output failures may result in a
hazardous accident.
24VDC power is required from a secondary circuit or a specific
power supply unit only.
Ensure the Ground Terminal of the Power Supply (C0-00AC/
C0-01AC) for the CLICK PLUS CPU is connected to Earth
Ground to avoid electric shock or equipment damage during a
short circuit.
Don’t operate the equipment with a nonconforming external
power supply to avoid electric shock, equipment damage or fire.
Don’t intentionally fault the wiring; this may cause equipment
damage or fire.
To avoid electric shock or malfunctions which might result in an
accident, don’t touch any terminal while the PLC power is on.
Don’t put metals (e.g. screwdriver) into vent holes, or drop trash
or foreign objects (e.g. wire cut-offs) into the device, in order to
avoid electric shock or equipment damage.
If the equipment is used in a manner not specified by the
manufacturer, the protection provided by the equipment may be
invalidated.
CAUTION
For use in Pollution Degree 2 Environment. Use and store the
equipment in an environment described in the specifications
(regarding temperature, humidity, vibrations, shock, etc.) in
order to avoid equipment damage or fire.
Ensure all wiring has strain reliefs in order to avoid damage to
insulation that might result in electric shock or fire.
Ensure secondary external power circuits are only live after PLC
control program is started; otherwise a malfunction or output
failure may result in a hazardous accident.
Don’t block the vent holes. This may cause an increase of inter-
nal temperature resulting in equipment damage or fire.
Don’t disassemble or modify equipment so as to avoid electric
shock, equipment damage, or fire.
Cut off all phases of the external power source before mainte-
nance work, thus avoiding electric shock or equipment damage.
Hardware Installation
ENCLOSURES
It is important to select the appropriate enclosure to ensure
safe and proper operation of your CLICK PLUS PLC
system. Please use this product in a metal enclosure/cabinet.
Control applications vary and yours may require additional
considerations. At a minimum your enclosure should include:
Conformance to electrical standards
Protection from the elements in an industrial environment
Common ground reference
Maintenance of specified ambient temperature
Access to equipment
Security or restricted access
Sufficient space for proper installation and maintenance of
equipment
CLEARANCES AND ORIENTATION
Mount the unit horizontally to
provide proper ventilation.
There is a minimum clearance
requirement of 2in. (51mm)
from all sides of the cabinet and
the equipment.
There is a minimum clearance
requirement of 1.5 in. (38mm)
from the wiring ducts and the
equipment
Do not mount the unit upside down, on a horizontal surface, or
in a vertical arrangement.
Minimum clearance requirement
of 51mm for A, B, and C.
