Installation; Electric Connections; Hydraulic Connections - Enerpac SFP Serie Manuel D'utilisation

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 high
force tool equipment. In case of doubt, contact
Enerpac.
4.1 Transportation
The frame has two forklift truck pockets 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 follows:
Dwg 1
Motor size KW
Motor size Hp
The disconnection and line circuit protection will be
provided by the customer. Line circuit protection will be
115% of motor full load current at maximum pressure
of application.
IMPORTANT: The pumps with reservoir of 40 l. (10
gal) require correct motor rotation. After connecting the
male plug to the electric main power, start the motor
and check rotation against the arrow label on the motor
and correct phase if required.

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 back and
forth between the advance and retract positions with
the motor switched off (manual valves). For solenoid
valves turn the handle clockwise completely on every
valve as shown in the picture below (make sure to
unlock the locknut) and leave valves deactivated.
Connect the hydraulic hoses as follows:
1. Port A to the advance side of the cylinder
2. 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.
