•
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 (starter panel assembly for multi-pump (300-480 V) shown).
b) Connect the grounding wire to the lug labeled PE GND (protective earth ground).
Caution:
Incorrect motot rotation at high pressure 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.
