NOTE: The appliance should be permanently connected to ground during operation.
Connect Power to SSR1200
The AC power supply units (PSUs) in an SSR1200 are hot-removable and hot-insertable field-replaceable
units (FRUs). You can remove and replace the PSUs without powering off the appliance or disrupting its
functions.
Before you begin to connect AC power to the appliance:
• Ensure that you have connected the appliance chassis to an earth ground.
CAUTION: Before you connect power to the appliance, a licensed electrician must
attach a cable lug to the grounding and power cables that you supply. A cable with an
incorrectly attached lug can damage the appliance (for example, by causing a short
circuit).
To meet safety and electromagnetic interference (EMI) requirements and to ensure
proper operation, you must connect the chassis to an earth ground before you connect
it to power. For installations that require a separate grounding conductor to the
chassis, use the protective earthing terminal on the appliance chassis to connect to the
earth ground. The appliance gains additional grounding when you plug the PSU in the
appliance to a grounded AC power outlet by using the AC power cord appropriate for
your geographical location.
• Ensure that you have a power cord appropriate for your geographical location available to connect
AC power to the appliance.
• Read
"General Electrical Safety Guidelines and Warnings" on page 73
and
Electrical Accident" on page 73
.
• Ensure that you have taken the necessary precautions to prevent electrostatic discharge (ESD)
damage.
• Ensure that you have an ESD grounding strap.
• If not already installed, install the power supplies in the appliance.
