CHAPTER 13
Providing Power to the TCX1000-RDM20
• Connecting AC Power to a TCX1000-RDM20 on page 73
• Connecting DC Power to a TCX1000-RDM20 on page 75
Connecting AC Power to a TCX1000-RDM20
Before you begin connecting AC power to a TCX1000-RDM20 :
• Read “Prevention of Electrostatic Discharge Damage” on page 178 and “General Electrical
Safety Guidelines and Warnings” on page 177 .
•
Ensure that you have taken the necessary precautions to prevent electrostatic discharge
(ESD) damage (see
“Prevention of Electrostatic Discharge Damage” on page 178 ).
• Ensure that you have connected the TCX1000-RDM20 chassis to earth ground.
CAUTION: Before you connect power to the TCX1000-RDM20, 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 switch
(for example, by causing a short circuit).
NOTE: 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. For installations that require
a separate grounding conductor to the chassis, use the protective earthing
terminal on the TCX1000-RDM20 chassis to connect to the earth ground
(see
“Connecting the TCX1000-RDM20 Grounding Cable” on page 70 ).
NOTE: An AC-powered TCX1000-RDM20 gains additional grounding when
you plug the power supply in the device into a grounded AC power outlet
by using an AC power cord appropriate for your geographical location. See
“TCX1000-RDM20 AC Power Cord Specifications” on page 51 .
