3.2.11.1. Mains power connection AC
1. Take the Mains power cable that was delivered with the RU.
2. Locate or install a suitable power junction box or receptacle near the RU and
route the power cable from the power source to the RU. Do not connect the
cable to the RU’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 RU to plug
or unplug the cable into the Mains connector of the RU.
4. Wire the power cable to the junction box or receptacle. Refer to the color code
and pin numbers shown in
figure 3-18 (AC cable), and table 3-2.
5. With the cable’s Mains plug disconnected from the RU, 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 RU (figure
3-17).
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.
