Delta 31-140 Manuale Utente

A separate electrical circuit should be used for your machines. This circuit should not be less than #12 wire and should 

be protected with a 20 Amp time lag fuse. If an extension cord is used, use only 3-wire extension cords which have 

3-prong grounding type plugs and matching receptacle which will accept the machine’s plug. Before connecting the 

machine to the power line, make sure the switch (s) is in the "OFF" position and be sure that the electric current is of 

the same characteristics as indicated on the machine. All line connections should make good contact. Running on low 

voltage will damage the machine.

Your machine is wired for 115 volts, 60 HZ alternating current. Before connecting the machine to the power source, 

make sure the switch is in the “OFF" position.

1.  All grounded, cord-connected machines: 
In the event of a malfunction or breakdown, grounding provides a path of least resistance for electric current to reduce 

the risk of electric shock. This machine is equipped with an electric cord having an equipment-grounding conductor and 

a grounding plug. The plug must be plugged into a matching outlet that is properly installed and grounded in accordance 

with all local codes and ordinances.
Do not modify the plug provided - if it will not fit the outlet, have the proper outlet installed by a qualified electrician.
Improper connection of the equipment-grounding conductor can result in risk of electric shock. The conductor with 

insulation having an outer surface that is green with or without yellow stripes is the equipment-grounding conductor. If 

repair or replacement of the electric cord or plug is necessary, do not connect the equipment-grounding conductor to a 

live terminal.
Check with a qualified electrician or service personnel if the grounding instructions are not completely understood, or if 

in doubt as to whether the machine is properly grounded.
Use only 3-wire extension cords that have 3-prong grounding type plugs and matching 3-conductor receptacles that 

accept the machine’s plug, as shown in Fig. A.
Repair or replace damaged or worn cord immediately.
