CAUTION: Do not mix AC and DC power modules within the same router.
You connect AC power to the router with three-phase delta AC PDMs by connecting the
AC power cord from an AC PDM to an AC power source.
To connect an AC power cord to an AC power source:
Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect
1.
the strap to an approved site ESD grounding point. See the instructions for your site.
Switch off the dedicated customer site circuit breakers. Ensure that the voltage across
2.
the AC power source cable leads is 0 V and that there is no chance that the cable
leads might become active during installation.
