2. Determine where to put the HPU. Consider the following:
•
The room dimensions must be adequate to accommodate the HPU.
–
Refer to your local electrical codes for the required free space
surrounding the HPU.
–
A minimum of 914.4 mm (36 in) between the ends of the HPU and any
obstruction.
–
The rear of the HPU can be as close as 25.4 mm (1 in) to the wall.
–
A minimum of 2362.2 mm (93 in) from the floor to an overhead
obstruction.
•
The HPU can fit through a standard 1.04-m or 41-in door.
•
The HPU can be moved by a fork lift, pallet jack, or over head crane. Read
the caution on the previous page.
•
Placement considerations should include proximity to the facility electric
power 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 72 dB (A) of sound pressure level fully
compensated in a free field acoustic environment.
3. 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 or six (if parallel phase conductors are used)
electrical power feed wires to the input lugs of the power disconnect in
a counterclockwise phase orientation as indicated by the L3, L2, and
L1 labels shown in the next figure (Model 505.90 shown, the location
of the disconnect and ground varies slightly on other models).
Incorrect motor rotation at high pressure can cause severe damage to your
HPU.
It is imperative that you verify proper motor rotation while in low pressure, as
described in Step 6, to assure proper operation of the HPU and to prevent
damage to the HPU.
