Table 41. Procedure options for AC power connection (continued)
Situation on site Procedure
The customer’s electrician is NOT available at the installation site,
but you have access to customer-supplied, labeled, power cables
(beneath a raised floor or overhead). Procedure B: Verify and connect on page 68
The customer’s electrician is NOT available at the installation site,
customer-supplied PDU source cables are already plugged into the
PDU and you have no access to the customer-supplied power
cables. Procedure C: Obtain customer verification on page 69
Procedure A: Working with the customer's
electrician onsite
Use this procedure if the customer’s electrician is available at the installation site.
This procedure requires three basic tasks that alternate between the customer's electrician, the Dell EMC CE and back to the customer's
electrician.
• Task 1: Customer's electrician
• Task 2: Dell EMC Customer Engineer (CE)
• Task 3: Customer's electrician
Procedure A, Task 1: Customer's electrician
About this task
NOTE: This task is performed by the customer's electrician.
Steps
1. Verify that the customer-supplied AC source voltage output on each customer-supplied PDU is within the AC power specification
shown in AC power specifications on page 70. Measure the voltage output of each power cable as shown in Figure 28. Circuit
breakers ON — AC power within specification on page 63.
2. Turn OFF all the relevant circuit breakers in customer-supplied PDU 1 and customer-supplied PDU 2.
3. Verify that the customer-supplied power cables connected to PDU 1 and PDU 2 have no power as shown in Figure 29. Circuit breakers
OFF — No AC power on page 64.
