If power cord(s) WERE NOT supplied with the unit, choose a cord based on the following information:

For units installed in the USA or Canada: Select a flexible, three-conductor power cord that is UL-listed and CSA-certified, with individual conductor wire size of #18 AWG, and with a maximum length of 4.5 meters. The power cord terminations should be NEMA Type 5-15P (three-prong earthing) at one end and IEC appliance inlet coupler at the other end.

Any of the following types are acceptable: SV, SVE, SVO, SVT, SVTO,

SVTOO, S, SE, SO, SOO, ST, STO, STOO, SJ, SJE, SJO, SJOO, SJT,

￿SJTOO, SP-3, SPE-3, SPT-3, G, W.

For units installed in all other countries: Select only a flexible, three-conductor power cord, approved by the cognizant safety organization of your country. The power cord must be of the type HAR (Harmonized), with an individual conductor wire size of 0.75 sq.mm. The power cord terminations should be a suitably-rated earthing-type plug at one end and an IEC appliance inlet coupler at the other end. Both of the power cord terminations must carry the certification label (mark) of the cognizant safety organization of your country.

Plugging in the Unit

To plug in the unit:

1Plug the power cord into the power source.

2Plug the other end of the cord into the AC inlet located in the topmost section of the CoreBuilder 7000 family ATM switch front panel. Make sure the power cord is fully seated. A green power LED on the power supply should be lit. The unit is automatically powered up when the power cord is plugged in.
