11 Commissioning
The following subsections detail the procedure required to commission and start up the
UPS Solution. Refer to section 10 for details on isolation switch locations and section
12.3.1 for information on the Alpha FXM UPS unit's three-button interface.
All commissioning results must be recorded within the UPS Commissioning Certificate
found in APPENDIX D – UPS Commissioning Certificate. The certificate must then be
presented to the customer as part of the installation handover process. A copy must also
be retained by Siemens Traffic Solutions. A copy should also be kept within the UPS
cabinet for reference during maintenance actions.
NOTE: In order to avoid unduly stressing the UPS Solution it is advisable to
follow the switch on procedure set out below.
WARNING: Ensure all power sources are switched off and safely isolated
before starting the commissioning process. All switches and MCBs should
be in the OFF or BYPASS position.
WARNING: Any traffic controller, Siemens type or third party, which is powered
via the UPS solution must be fitted with a 300mA RCD. See section 7.2 for
more details.
11.1 Electrical Safety Testing
Upon completion of UPS Solution installation, the following Electrical Safety Tests are to
be carried out before the solution is powered or switched on.
Tests required are set out in the TS Traffic Installation Testing Document
(667/HE/20664/000):
·
2.1 Test Gear Requirement
·
2.2 Core to Core Testing – This applies to all cables between Feeder Pillar and
·
2.3 Visual Inspection
·
2.4 Circuit Protective Conductor Test – This applies to all cables between Feeder
·
2.5 Basic Polarity Test
·
2.6 Site Insulation Test
·
2.7 Polarity Test
·
2.8 Earth Loop Impedance Tests – The UPS Solution needs to be in BYPASS for
this test as described in section 11.3.
·
2.9 RCD Test – A 300mA RCD must be fitted within the controller.
11.2 TT Earth Electrode Test
The bonded elements of the installation must be tested to confirm whether they form an
adequate TT earth electrode in case the incoming supply earth is lost.
ENSURE THE SUPPLY HAS BEEN SWITCHED OFF. The UPS cabinet must be
disconnected from the incoming supply earth. An Earth Loop Impedance Tester can then
be connected across the UPS Live output and the CET Plate in the base of the UPS
Cabinet and a test performed. This reading is taken as the earth electrode resistance.
