Electrical wiring workWARNING All wiring must be performed by an authorizedelectrician.All components procured on the side and all elecrticconstruction shall comply with the applicablelegislation.DANGER: HIGH VOLTAGE.To avoid electrical shock, make sure todisconnect the power supply 1 minute or morebefore servicing the electrical parts. Even after1 minute, always measure the voltage at theterminals of main circuit capacitors or electricalparts and, before touching , make sure thatthose voltages are 50VDC or less.NOTICETo persons in charge of electrical wiring work:Do not oerate the unit until the refrigerant pipingis complete. (Running it before the piping isready will break the compressor.)10.1. Precautions on electrical wiring work When servicing the unit requires the refrigerantsystem to be opened, treatment and evacuationof refrigerant must be done in accordance withapplicable legislation. Refrigerant can not be chargeduntil field wiring has been completed.Refrigerant may only be charged after performing theleak test and vacuum drying.DANGER Before obtaining access to terminal devices, allsupply circuits must be interrupted. Be sure to install an earth leakage circuit breaker inaccordance with aplicable legislation. Failure to doso may cause electrical shock. Use only copperwires. A main switch or other means for disconnection,having a contact separation in all poles, must beincorporated in the fixed wiring in accordance withapplicable legislation. Do not turn on the main switchuntil all the wiring is completed. Make sure to connect power supply cables in normalphase. Never squeeze bundled cables into a unit. Fix cables so that cables do not make contact withthe pipes (especially on high pressure side).1U140S2SP1FA/B 2.9 2.9 2.9 3.35 3.8 4.25 4.7 5.151U140S2SP1FA/B 2900 45 1250
