Power Connection
Follow these basic guidelines when working with any electrical equipment:
Before beginning any procedures requiring access to the chassis interior, locate the emergency power-off
switch for the room in which you are working.
Disconnect all power and external cables before moving a chassis.
Do not work alone when potentially hazardous conditions exist.
Never assume that power has been disconnected from a circuit; always check.
Do not perform any action that creates a potential hazard to people or makes the equipment unsafe.
Carefully examine your work area for possible hazards such as moist floors, ungrounded power extension
cables, and missing safety grounds.
To prevent the MCU from overheating, do not operate it in an area that exceeds the maximum
recommended ambient temperature of 113°F (45°C).
Power connection information:
Connecting the shelf to earth ground
WARNING
Protective ground must be connected to the chassis before connecting any external power. Not
connecting the grounding cable creates a high voltage hazard condition.
Recommended minimum specifications for the grounding cable and its connection include the following:
• Recommended Minimum Wire Size: 18 AWG (1 mm
2
)
• Recommended Terminals: Use only 4M ring terminal
Verify the supply output voltage (DC or AC) and the connection rating limitation (circuit breaker).
WARNING
Depending on the particular chassis design, operations with open equipment enclosures can
expose the installer to hazardous voltages with a consequent danger of electric shock.
Ensure that line power to the equipment is disconnected during operations that make high
voltage conductors accessible.
