You will need
- a screwdriver, a knife, a phase tester, pliers, ring spanners 14 and 17 (you can use carob 14х17), a warning sign "do Not switch! Work on the line, if necessary tips for finishing multi-strand wires.
Before you start, you need to de-energize the switchboard in which they will be working. On the switch, post a warning poster. To check the absence of voltage use the display with a screwdriver. Just touch the tip of the screwdriver all contacts and the index finger need to touch the contact on the handle.
After we verify the absence of voltage taken for training the plug-in cable. To do this, with a knife carefully remove the top insulation of the cable by a distance that will allow you to easily manipulate the cable shield when connecting. The next step will prepare the cable wires. The same knife remove the insulation from the wires. pliers (pliers) are preparing contacts (the ends of the wires vygeboom as circles). Key Unscrew the clips in the panel and connect our cable. When connecting you should pay attention that the cable is three wires one section, and the fourth less. It is used as the zero and is connected primarily to the zero bus. When connecting the cable, the stranded wire which is used tips for making contacts.
If the load is connected at the other end of the cable using a phase tester, which determine the direct sequence of phases (ABC). Upon completion of installation, the robot removed a warning poster and connect 380 V.
In conclusion, don't be too arrogant! If you are unsure or in doubt, better call a technician because the electricity does not forgive mistakes.
When routing and connecting wiring 380 V it must be remembered that this voltage is dangerous for life and all work related to electricity should be done by the specialist. But if You are not afraid, then proceed.
