Connect SSR120 to Power
Connect Earth Ground to SSR120
To meet safety and electromagnetic interference (EMI) requirements and to ensure proper operation, you must connect the chassis to earth ground before you connect it to power.
Before you connect an earth ground to the protective earthing terminal of an SSR120 appliance, ensure that a licensed electrician has attached an appropriate ground ring terminal to the grounding cable. Using a grounding cable with an incorrectly attached ring terminal can damage the appliance.
You ground the SSR120 by connecting a grounding cable to earth ground and then attaching the grounding cable to the chassis grounding point located on the rear of the appliance. Under all circumstances, use this grounding connection to ground the chassis. For AC-powered systems, you must also use the grounding wire in the AC power cord along with the one-hole grounding ring terminal connection. This tested system meets or exceeds all applicable EMC regulatory requirements with the one-hole protective grounding terminal.
To ground the appliance:
The appliance should be permanently connected to ground during operation.
Connect Power to SSR120
Ensure that you have a power cord appropriate for your geographical location.
To connect power to the appliance:
Power Off the SSR120
You can power off the SSR120 in one of the following ways:
Graceful shutdown—You can do a graceful shutdown in two ways:
Use the Linux
poweroff
command at the Console. The appliance begins gracefully shutting down the operating system and then powers itself off.Press and hold the POWER button for 3 seconds, then release. The appliance begins gracefully shutting down the operating system and then powers itself off.
CAUTION:Use the graceful shutdown method to power off or reboot the appliance.
Forced shutdown—Press and hold the POWER button for 7 seconds, then release. The appliance immediately powers itself off without shutting down the operating system.
CAUTION:Forced shutdown can result in data loss and corruption of the file system.
Use the forced shutdown method as a last resort to recover appliance if the appliance operating system is not responding to the graceful shutdown method.
Do not press the POWER button while the appliance is shutting down.
To remove power completely from the appliance, unplug the power cord or switch off the power source.
After powering off a power supply, wait at least 10 seconds before turning it back on. After powering on a power supply, wait at least 10 seconds before turning it off.
