WARNING
The pump requires correct motor rotation. After
connecting the plug to the main power supply, start
the motor and check rotation against the arrow label
on the motor and correct phase if required.
6.4.1 Manual SHS HPU Controls
The controls of the Manual SHS HPU are indicated on
the following picture:
Figure 12: Manual SHS HPU Controls
1. Control levers: The user controls the cylinder
movements manually with these levers. Pulling
up the levers will make cylinders pull or retract
and pulling down will make cylinders to extend or
advance. There can be more than one lever pulled
up or down at the same time.
2. Stop Motor Button: The HPU motor and pump will
power off if this button is pushed.
3. Start Motor Button: The HPU motor and pump will
power on if this button is pushed.
7. Screens
7.1 Main Screen
Figure 13: Main Screen
This is the main screen showed by the PRD when the
system is powered on. In this screen the system shows

CAUTION
Extend and retract the piston rods a few centimeters
before installing the cylinders under the hook.
Enerpac recomends this to be done while cylinders
are located in the transport structure. Check all
cylinders for leakage.
6.4 Electrical 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 will vary, depending on voltage and
motor size:
Motor Size
Electric Plug
7.5 kW
10 hp
3Ph + PE 400V 16A
11 kW
14.75 hp
3Ph + PE 400V 32A
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.
If the cylinder includes pressure transducers or stroke
sensors, in order to connect them to the HPU, the user
must connect a cable from the sensor connection port,
which is connected to the electrical distribution box of
the cylinders safety block, to the connectors on top of
the Pressure Reading device.
