Mounting and Grounding the Power Supply
CAUTION – Electrical Shock Hazard
Failure to properly ground the power unit may result in electrical shock hazard
to personnel and inefficient operation of the Conveyostat.
1. Mount the power unit to the machine frame or to a convenient wall or post. Mount
the power unit to a flat surface using the mounting flanges at the base of the power
unit. Be sure to position it so that the power unit’s case is properly grounded in order
to ensure safe and efficient operation of the Conveyostat.
2. Ground the Dual Phase+ Power Supply by the following method: When installing the
AC line power wiring, use 3-conductor cable. Two conductors will supply the line
voltage. The third conductor will provide the ground connection between the ground
at the power source (junction box or panel) and the ground post on the inner side of
the wiring compartment of the power unit’s case.
High Voltage Connections
The Conveyostat wiring always terminates in to two black cables. Each cable is connected
to altering static bars in the Conveyostat and then to two different transformers in the
power supply.
Because we are using high voltage, 4000 VAC, and sources that are out of phase with
each other, it is important that the black cables be separate from each other and isolated
from any grounded material. If wire isolation is not adequate, damage to the wire may
occur, degrading system performance. Technically, the cables may be 100 feet long with
no problems if isolated.
To insure the best possible performance, the ground wire (braided metal strap) should be
used to connect the power supply to the Conveyostat. If not possible, the electrician must
insure that both the power supply and Conveyostat are connected to the same ground level
The outdoor units have special needs. The cables must be in weather tight conduit until
they connected to the power supply or run into the building. Any supply wiring to the
power from inside the plant must be sealed so no plant air can enter the outdoor box. The
box itself must be sealed from the outside environment.
The power supply is to be connected to a grounded, 120 VAC supply. As mentioned
before, the supply ground must be the same ground that the Conveyostat is connected to.
That is accomplished by using the braided cable or ensuring the common grounding of
both devices. If the grounding is not as specified here, the power supply transformers will
fail in a very short time.
