Main power cable
You must prepare the power cables to connect the 4072/4073 tester to the switchboard because it is not bundled
with the tester. This chapter describes how to prepare the main power cables.
Figure 2-11 Connecting power cable
When you connect the ground wire to the PDU of the system cabinet, use the terminal as shown in Figure 2-11.
Table 2-5 shows the main power cable specification. The cable must comply with the local regulation.
If you need to perform an ELECTRICAL SAFETY LEVEL CHECKS before the installation, see Appendix A ,
“Confirming the System Power Safety” to connect the site power line to the 4072/73 tester and check it.
NOTE The torque specifications of the power cable connections at the PDU are 4.0 N-m for 208/220/240
V and 2.5 N-m for 200 V option.
