Electric Pump Installation

NOTE: Electric Grease Jockey pumps are available with

or without a timer. Choose the appropriate installation

section.

Fuses

The following fuse information applies to all models:

• Use standard automotive style blade fuses, ATO

series 257. Fuses are available from your Graco

distributor.

• Never use a higher amperage capacity fuse. Dam-

age to the pump and vehicle electrical system could

occur.

• Install fuse holders in a protected area, as far from

the pump as possible. This will provide maximum

protection to the vehicle electrical system.

Pump Models without a Timer

Refer to Wiring Schematic (FIG. 4) for these instructions.

1. Install 10 Amp fuse (12 VDC models) or 5 Amp fuse

(24 VDC model) in line with the White wire con-

nected to the first pole of the Hirschmann connector.

2. Wire as follows. If using a Graco mating cable, the

wire color corresponding to the 3-Pole Hirschmann

connection point is provided in parenthesis.

• Chassis Ground (-) to Hirschmann connection,

labeled number 2 (Black wire)

• Ignition (+) to Hirschmann connection, labeled

number 1 (White wire) - This source should only

provide a voltage supply when the vehicle igni-

tion switch is on.

NOTE: The Hirschmann connection labeled ground, or

the green wire of a Graco mating cable, is not used for

either voltage models.

Pump Models with a Timer

Refer to Wiring Schematic (FIG. 5) for these instructions.

1. Install 10 Amp fuse (12 VDC model) or 5 Amp fuse

to the first pole of the Hirschmann connector

(applies to both 12 and 24 VDC models).

connection point is provided in parenthesis.

• Chassis Ground (-) to Hirschmann connection,

labeled number 2 (Black wire)

• Battery (+) to Hirschmann connection, labeled

number 1 (White wire) - This source should

always provide a voltage supply.

• Ignition (+) to Hirschmann connection, labeled
