4.4.2 Guidelines for electrical connection
• Check that the mains voltage and frequency match the specifications on the data plate.
• Protect the supply cord from high temperatures, vibrations, collisions and abrasions.
• Check that the power supply line is provided with a short circuit protection device of
appropriate size.
• If the pump unit is supplied with a power cord with grounding-type attachment plug, connect
it only to a properly grounded, grounding-type receptacle.
• Do not use an extension cord.
• If the pump unit is supplied without a power cord, use only a (UL) certified, SJTW type, PVC
insulated and sheathed, hard service flexible cord with copper conductors, with a cross
section of 18 AWG. Follow the next connection steps.
