MTS Model 506-62-72 Hydraulic Power Supply - Manual (Page 31)

Installation 4-3
4.2 Electrical Connections
The HPS is operated from a three-phase electrical power source. The
operating voltage is labeled on the outside of the starter assembly and
on the pump motor.
Before you begin
Install a fused power disconnect switch (customer supplied). This
switch removes electrical power to the HPS. Local codes dictate the
type of switch to be used. Electrical connections must be made by
qualified personnel and conform to local codes and regulations.
WARNING !
When the electrical connections have been made, high voltage is
present in the starter assembly when power is on. Do not open the
starter box door with power applied to the HPS.
Touching components with high voltage can cause death.
Remove electrical power at the power disconnect switch before you open
the front starter box door.
