Enerpac SFP-Series - Manual (Page 3)

4.0 INSTALLATION
Visually inspect all components for shipping damage.
Shipping damage is not covered by warranty. If
shipping damage is found, notify carrier at once. The
carrier is responsible for all repair and replacement
costs resulting from damage in shipment.
Install or position the pump to ensure that air flow
around the motor and pump is unobstructed. Keep the
motor clean to ensure maximum cooling during
operation.
IMPORTANT: Eliminate the presence of side load
forces when using hydraulic cylinders. Side load can
occur through:
1. An eccentric load on the plunger.
2. A horizontal load on a structure.
3. A structure and/or cylinder misalignment.
4. Non synchronized lifting actions.
5. Non stable cylinder base support.
Always use a flat, hard surface as a cylinder support
plate. Use a low friction material on top of the saddle.
To reduce cylinder offset loading, optional CATG-
swivel saddles are available. Always use grease
underneath swivel saddles.
IMPORTANT: It is mandatory that the operator has a
full understanding of all instructions, safety regulations,
cautions and warnings, before starting to operate any
of this high force tool equipment. In case of doubt,
contact Enerpac.
4.1 Transportation
For transportation the frame has two forklift truck
pockets that make available for forklift lift, and four
hoisting certified eyes for lifting with cranes.

4.2 Electric connections
The pump is factory equipped with a 3
phase electrical plug for the given voltage,
altering the plug type should only be done by
a qualified electrician, adhering to all applicable local
and national codes.
The plug supplied is set as follow: 3+N+PE 380V 16 A
1. The disconnection and line circuit protection to be
provided by customer. Line circuit protection to be
115% of motor full load current at maximum pressure
of application.
IMPORTANT: The pumps with reservoir of 40 L. have
the motor rotation direction sense. When connect the
male plug to the electric main power, be sure that there
is in the correct phase. If not, change the phase of the
motor.
4.3 Hydraulic connections
WARNING: On double-acting cylinders be certain that
hoses are connected to BOTH couplers. Never attempt
to pressurize a double-acting cylinder if only one hose
is connected.
IMPORTANT: To decompress ports prior to connecting
hoses, move the manual valve several times in position
advance and retract with the motor switched off
(manual valves). For solenoid valves turn clockwise
completely the valve handler in every valve as showed
in the picture (previous unlock the locknut) and leave
finally valves deactivated.
Connect the hydraulic hoses using the following
diagram.
Port A to the advance side of the cylinder
Port B to the retract side of the cylinder (only for double
acting cylinders, for single acting cylinder leave it
disconnected).
Follow the next steps to correctly connect the hoses:
1. Keep cylinder connected to a hydraulic system with
a fluid cleanliness level minimum of NAS 1638 Class 6.
2. Remove dust covers/rubber plugs from oil ports
3. Inspect all threads and fittings for signs of wear or
damage and replace as needed.
4. Clean all threads and fittings.
5. Make hydraulic connections for double-acting
cylinders using two hoses.
6. Fully hand-tighten all couplers. Loose coupler
connections will block the flow of oil between the pump
and the cylinder.
7. Check for leaks in system and have repaired by
qualified personnel.
