Mechanical Installation
Grounding
Panel Box: The panel box must be properly connected to earth ground to provide a good common ground ref-
erence.
Panel Door: Tie a low impedance ground strap between the panel box and the panel door to ensure that they have
the same ground reference.
WARNING: Be sure meet the ground requirements of the panel manufactuer and also meet applicable electrical
codes and standards.
Temperature / Ventilation
Ensure that the panel layout design allows for adequate ventilation and maintains the specified ambient tem-
perature range. Consider the impact on the design of the panel layout if operating at the extreme ends of the ambi-
ent temperature range. For example, if it is determined that a cooling device is required, allow adequate space and
clearances for the device in the panel box or on the panel door.
Noise
Consider the impact on the panel layout design and clearance requirements if noise suppression devices are
needed. Be sure to maintain an adequate distance between the OCS and noisy devices such as relays, motor
starters, etc.
Shock and Vibration
The OCS has been designed to operate in typical industrial environments that may inflict some shock and vibration
on the unit. For applications that may inflict excessive shock and vibration please use proper dampening techniques
or relocate the OCS to a location that minimizes shock and/or vibration.
Panel Layout Design and Clearance Checklist
The following list provides highlights of panel layout design factors:
n
Meets the electrical code and applicable standards for proper grounding, etc.?
n
Meets the panel manufacturer’s requirements for grounding, etc.?
n
Is the panel box properly connected to earth ground? Is the panel door properly grounded? Has the appro-
priate procedure been followed to properly ground the devices in the panel box and on the panel door?
n
Are minimum clearance requirements met? Can the panel door be easily opened and closed? Is there
adequate space between device bases as well as the sides of the panel and wiring ducts?
n
Is the panel box deep enough to accommodate the controller?
n
Is there adequate ventilation? Is the ambient temperature range maintained? Are cooling or heating devices
required?
n
Are noise suppression devices or isolation transformers required? Is there adequate distance between the
base of the controller and noisy devices such as relays or motor starters? Ensure that power and signal wires
are not routed in the same conduit.
n
Are there other requirements that impact the particular system, which need to be considered?
