3.11 Connecting the Power Cables
1. After completing the set up, connect the interconnect cable to the Control Unit and to the
Power Supply. A 0.6 m (2 ft) [or a 3 m (10 ft) for remote mounting] interconnect cable is
supplied with your Controller and has identical 25 pin connectors at both ends. Secure the
ends at the Power Supply connector and the Control Unit connector using the two captive
screws on each connector.
2. If you have not already done so, verify that the line voltage switches are set properly. See
Section 2.2 on page 2-14.
3. Connect the power cable to a grounded outlet.
4. Assuming you have completed the set up and installation according to the foregoing
instructions, the Stabil-Ion System should now be ready to turn on and operate.
If you are
using the Process Control Option, you must prepare for process control operation before
turning ON the 370 in automatic mode.
See Section 4.11 on page 4-31. Attempting automatic
operation with process control before the controls are properly set can cause costly damage
and even be dangerous.

Compliance with the usual warning to connect the power cable only to a
properly grounded outlet is necessary but not sufficient for safe operation of
a vacuum system with this or any similar high voltage producing product.
Grounding this product does not and cannot guarantee that other
components of the vacuum system are all maintained at Earth ground.
It is the installer's responsibility to ensure that the automatic signals
provided by the product are always used in a safe manner. Carefully check
the system using manual operation and the setpoint programming before
switching to automatic operation.
Where an equipment malfunction could cause a hazardous situation, always
provide for fail-safe operation. As an example, in an automatic backfill
operation where a malfunction might cause high internal pressures, provide
an appropriate pressure relief device.
Installation and wiring must be in compliance with your local building and
electrical codes. CONNECT THE POWER CORD ONLY TO A PROPERLY
GROUNDED OUTLET.
Primary Mains disconnect is provided by the A.C. Power Cord. Install unit so
there is access to the A.C. Power Cord.
