Graco 260028 Manual De Usuario

To install wiring for a negative ground system:

1. Ensure pump switch is OFF.

2. To remove electrical cover (2a), remove four bolts 

(2c).

3. Strip 3 in. (76 mm) of outside insulation from power 

cable (6c) from end opposite of fuse. 

4. Strip 3/8 in. (10 mm) of insulation from red and black 

wires.

5. Slide strain relief (6b) over end of power cable (6c) 

on the end just stripped. Male thread of strain relief 
should be toward stripped end.

6. Insert power cable through conduit thread in electri-

cal cover (2a). Connect wires from power cable to 
wires from the motor using wire nuts (2e): red to red 
and black to black.

7. Screw strain relief (6b) into electrical cover (2a). 

8. Position power cable (6c) so the large diameter of 

power cable extends through strain relief (6b).

9. Tighten nut on strain relief to form a seal around the 

power cable.

10. Reinstall electrical cover (2a) on the pump.

11. Remove 1/2 in. (13 mm) of insulation from wires on 

the fuse holder end of the power cable.

12. Attach battery clamps (6a) with red sleeve to red 

wire and black sleeve to black wire. Wire must be 
crimped to the battery clamp firmly to get a good 
electrical connection.

13. Connect red wire with fuse holder inline to positive 

battery terminal. Connect black wire to negative bat-
tery terminal. 

1. Ensure pump switch is OFF and electrical power is 

disconnected.

2. Install conduit and user-supplied power cord to 

pump.

3. Strip 3 in. (76 mm) from power cord jacket and 1/2 

in. (13 mm) from individual conductor insulation. 

4. To remove electrical cover (2a), remove four bolts 

(2c).

5. Remove 1/2 in. (13 mm) of insulation from power 

wires inside pump electrical terminal cavity.

6. Insert electrical power wire through conduit opening 

in back of pump.

7. Using wire nuts (2e), connect wires: green to green, 

white to white, and black to black.

8. Replace electrical cover.

If you are installing models 260580 or 260581 skip 
this section. These pumps have been factory wired

Power cable can be cut to shorter length if 18 feet 
(5.5 m) is not required. Cut to proper length and 
proceed with steps 3 and 4.

On 115 VAC and 230 VAC pumps, electrical con-
nections must be made by a licensed electrician per 
requirements of local, state, and national codes 
regarding class 1, group D installations. Only rigid 
conduit with threaded connections should be used. 
Conduit opening in pump must be sealed with 
waterproof, fuel-resistant sealant. Failure to comply 
with this warning could result in injury from electrical 
shock.
