3.6.4 Orientation
When panel-mounted, there are no orientation restrictions on the XL4 OCS.
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 XL4 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 XL4 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 XL4 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 XL4 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 XL4 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?
