Use the information in this section when designing your enclosure and
planning to mount your 8720MC-RPS unit and accessories on the panel.

System Mounting Requirements

• To comply with UL and CE requirements, the drive system powered by
the 8720MC-RPS unit must be mounted in a grounded conductive
enclosure offering protection as defined in standard IEC 60529 to IP20
such that they are not accessible to an operator or unskilled person.
To maintain the functional safety rating of the Kinetix® drive system, this
enclosure must be appropriate for the environmental conditions of the
industrial location and provide a protection class of IP54 or higher.
• The panel you install inside the enclosure for mounting your system
components must be on a flat, rigid, vertical surface that won't be
subjected to shock, vibration, moisture, oil mist, dust, or corrosive
vapors in accordance with pollution degree 2 (EN 61800-5-1) because
the product is rated to protection class IP20 (EN 60529).
• Size the system enclosure so as not to exceed the maximum ambient
temperature rating. Consider heat dissipation specifications for all
system components.
• Segregate input power wiring from control wiring and motor cables.
• Use high-frequency (HF) bonding techniques to connect the modules,
enclosure, machine frame, and motor housing, and to provide a low-
impedance return path for high-frequency (HF) energy and reduce
electrical noise.
Bond the 8720MC-RPS unit and accessory grounding screws by using a
braided ground strap as shown in
Refer to the System Design for Control of Electrical Noise Reference Manual,
publication GMC-RM001, to better understand the concept of electrical noise
reduction.
