Installation
This section describes how to install the Series 505 Hydraulic Power Unit (HPU).
Note The HPU is designed for indoor use. The HPU should be stored and
installed indoors.
Install the HPU
1. Position the hydraulic power unit.
Determine where to put the HPU. Review the following:
• The HPU can fit through a standard 1-m or 36-in door.
• The HPU can be moved by a fork lift, pallet jack, or dolly.
• Placement considerations should include proximity to the facility
electric power, water, and the hydraulic components. Positioning the
HPU close to the hydraulic components can reduce the cost of
hydraulic distribution.
• The HPU produces no more than 60 dB (A) of sound pressure level
fully compensated in a free field acoustic environment.
• Connect the electrical service to the HPU.
Note Local electrical codes supersede any information found here.
Electrical connections must be made by qualified personnel and conform to
local codes and regulations. The electrical box has a power disconnect
switch that must be off (O) in order to open the electrical box. An electrical
service panel to provide the electrical power feed (line voltage) to the HPU
is not necessary, but may be required by local electrical codes.
A. Connect the three electrical power feed wires to the input lugs of the
power disconnect in a clockwise phase orientation as indicated by the
L1, L2, and L3 labels shown in the following figure (the Model 505.07/
.11 high voltage configuration is shown).
Incorrect motor rotation at high pressure for longer than 10 seconds can
cause severe damage to your HPU.
It is imperative that you verify proper motor rotation to assure proper operation of
the HPU and to prevent damage to the HPU.
