d.
Orientation
Observe guidelines for proper orientation of the bases when mounting the MiniOCS / MiniRCS (page 25).
Proper orientation helps to ensure a good connection when MiniOCS / MiniRCS models are installed into
the devices.
e.
Noise
Consider the impact on the panel layout design and clearance requirements if noise supression devices
are needed. Be sure to maintain an adequate distance between the MiniOCS / MiniRCS and noisy
devices such as relays, motor starters, etc.
Note: Do not route power and signal wires in the same conduit.
2.3.1
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? (See page 25.)
____Are minimum clearance requirements met? (See Table 2.1.) 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 MiniOCS / MiniRCS. (Be sure to consider the
Ground Screw extension.)
____Are the device bases oriented correctly? (See page 25.) The MiniOCS / MiniRCS devices are
mounted on the door of a panel box.
____Is there adequate ventilation? Is the ambient temperature range maintained? Are cooling or heating
devices required?
____Are noise suppression devices or isolation transformers be required? Is there adequate distance
between the base of the MiniOCS / MiniRCS 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?
Warning: To provide maximum noise immunity and to insure minimum EMI radiation, the V-
signal (DC power return) need to be connected to earth ground at the power supply. The user must
ensure that the power supply selected is compatible with this method of grounding.
