4.1.2 Make Power Connections
After the STS 2000A unit is correctly positioned, make power connections to input and output buses as
described in
2.8.2 Customer Power Connections.
4.1.3 Commissioning: Initial Power-up Site Test
A PDI certified technician must commission and perform acceptance testing on the STS 2000A unit to
initiate warranty coverage. All the work performed in this section must be performed or witnessed by a
PDI Service Representative.
The commissioning sequence is as follows:
1. Before applying input power to the STS, the Installer and the PDI Service Representative should
perform the following checks:
a. Verify that the incoming power matches the unit rating (building electrical service and voltage)
match the unit rating and the STS 2000A Bill of Materials.
b. Check the customer connections to input and output buses.
c. Verify that the STS is connected to the grounding electrode conductor.
2. Before applying input power to the STS, open all MCCBs and MCSWs in the STS.
3. With all internal MCCBs and MCSWs open, apply power to the unit by energizing the building
power circuit breaker or UPS output circuit breaker supplying the STS 2000A unit.
4. Perform the following measurements:
a.
Measure the incoming voltage at input to the unit. Incoming voltage should match the unit’s
rating (-10% to +5% of nominal rating).
b. Check for correct phase rotation (clockwise) and voltage at the source 1 Power Input bus.
c. Verify input phasing is correct as given in 4.1.5 Phasing Verification Procedure .
5. The initial bring-up must be performed in Bypass Mode:
a. Close Bypass 1 MCCB and verify output voltage is present.
b. Open Bypass 1 MCCB; close Bypass 2 MCCB; and verify output voltage is present.
4.1.4 Commissioning: Acceptance Testing
As part of acceptance testing, the STS should pass a Performance Test at 80% load minimum.
A PDI service technician will perform or witness the Site Acceptance Test as indicated in the "Site
Acceptance Report.” The technician will then ask the customer representative to sign the completed
Acceptance Test Report/Work Order. The Warranty Period begins when the customer signs the
Acceptance Test/Work Order.
4.1.5 Note on STS Testing and Commissioning Methodology
The PDI WaveStar Static Transfer Switch (STS) has built in redundant logic and transfer abilities. The
primary logic is connected to the line side of input Molded Case Switches (MCSW) and output bus in the
static switch to detect upstream events
– this then allows the switch to sense and transfer sources. The
