XL7 User Manual
3.6.5 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 XL7 OCS and noisy devices such as
relays, motor starters, etc.
For details on output protection, especially when using contactors, solenoids… see MAN0962-01-EN.
3.6.6 Shock and Vibration
The XL7 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 XL7 OCS to a location that minimizes shock and/or
vibration.
3.6.7 Panel Layout Design and Clearance Checklist
The following list provides highlights of panel layout design factors:
 Meets the electrical code and applicable standards for proper grounding, etc.?
 Meets the panel manufacturer’s requirements for grounding, etc.?

Is the panel box properly connected to earth ground? Is the panel door properly grounded?
Has the appropriate procedure been followed to properly ground the devices in the panel box
and on the panel door?

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?
 Is the panel box deep enough to accommodate the XL7 OCS?

Is there adequate ventilation? Is the ambient temperature range maintained? Are cooling or
heating devices required?

Are noise suppression devices or isolation transformers required? Is there adequate distance
between the base of the XL7 OCS and noisy devices such as relays or motor starters? Ensure
that power and signal wires are not routed in the same conduit.
 Are there other requirements that impact the particular system, which need to be considered?
