1. Take the Mains power cable that was delivered with the EU.
2. Locate or install a suitable power junction box or receptacle near the EU and
route the power cable from the power source to the EU. Do not connect the
cable to the EU’s Mains connector at this time. The power source must be
interruptible.
3. The Mains cable must be properly secured observing local regulations and
electrical codes. Be sure to allow enough slack in the cable at the EU to plug
or unplug the cable into the Mains connector of the EU.
4. Wire the power cable to the junction box or receptacle. Refer to the color code
and pin numbers shown in figure 4-16 (AC cable), and table 4-3.
5. With the cable’s Mains plug disconnected from the EU, turn the circuit breaker
on, unscrew the plug’s protective cover, and carefully test the plug with a
voltmeter to ensure that the voltage and polarity are correct.
6. Once the testing has been completed, turn off the circuit breaker.
7. Unscrew the protective cover from the Mains connector of the EU (figure
4-15).
8. Insert the plug into the Mains connector and tighten the clamping ring until it is
hand tight. Do not over-tighten the clamping ring.
