The provided cable lugs in an EX9214 switch are sized for 6 AWG (13.3 mm

), minimum 60°C wire. We
recommend that you install heat-shrink tubing insulaon around the power cables and lugs.

• Phillips (+) screwdriver, number 2
• Mulmeter
You can install four DC power supplies in EX9214 switches.
WARNING: Before performing DC power procedures, ensure that power is removed
from the DC circuit. To ensure that all power is o, locate the circuit breaker on the
panel board that services the DC circuit, switch the circuit breaker to the OFF posion,
and tape the switch handle of the circuit breaker in the OFF posion. Verify that the
INP0 OK and INP1 OK LEDs are o.
CAUTION: Before you connect power to the switch, a licensed electrician must aach a
cable lug to the grounding and power cables that you supply. A cable with an incorrectly
aached lug can damage the switch (for example, by causing a short circuit).
CAUTION: Do not mix dierent types of power supplies (AC and DC) in the same
chassis.
NOTE: Each power supply input feed must be connected to a dedicated DC power source outlet.
WARNING: Ensure that the power cords do not block access to switch components or
drape where people can trip on them.
To connect DC power to an EX9214 switch:
1. Switch o the dedicated customer site circuit breakers. Ensure that the voltage across the DC
power source cable leads is 0 V and that there is no chance that the cable leads might become
acve during installaon.
2. Aach the ESD grounding strap to your bare wrist, and connect the strap to the ESD point on the
chassis.
