3.3. Upgrade grid
The HVC-PD E-Bus Charger can be connected directly to the electrical grid or to an existing
customer low voltage power distribution cabinet. In both cases a 198 A, 480/277 V AC or for
the Canada version a 168 A, 600/347 V AC, 60 Hz, 3P+GND connection to each Power
Cabinet (HVC 150 or HVC 150S) is required. For each Power Cabinet (HVC 150 or HVC
150S) is necessary that meets the following requirements:
3 phase 250 A Circuit Breaker.
Main switch.
GND connected to the main GND rail.
The components used in the HVC-PD E-Bus Charger are suited for a short circuit
capacity of 65 kA.
A TN-C earthing system. Possibly an extra 0.9 Ω earth electrode is required, consult
the grid owner.
EMC filter is required to meet EMC conducted emission class B: Schaffner type FN
3359HV-400-99. When EMC conducted emission class A is required there is no filter
required.
Specifications of the following parts must be determined by your electrical engineer.
They depend on local laws, safety and electrical regulations:
Adjustable GFCI in the range of 30 mA up to 300 mA. The Power Cabinet has
an integrated 300 mA GFCI (Type A) for the power section.
UL 1449 Type 1 Surge Protection Device (SPD).
3.4. Location
The location of the HVC-PD E-Bus Charger must meet the following requirements:
The charging system should not be installed in the hazardous location identified per
the standard ANSI/API RP 500-2012: Recommended Practice for Classification of
Locations of Electrical Installations at Petroleum Facilities Classified as Class I,
Division 1 and Division 2.
The height is not more than 6561.68 ft above sea level.
The HVC-PD E-Bus Charger must not be immersed in water, or any other fluid.
The operational temperature of the HVC-PD E-Bus Charger is between -35 and 45 ⁰C.
For locations where the Power Cabinet will be exposed to direct sunlight and
high ambient temperatures for most of the day, it is recommended to install
protection from direct sunlight. Otherwise, the temperature inside the cabinet
might exceed the maximum temperature.
Do not install or use the HVC-PD E-Bus Charger in areas where there is an explosion
hazard. You must provide information about the HVC-PD E-Bus Charger to the fire
brigade.
The protection rating of the housing of the Power Cabinet is IP54 while the ACS Control
Module is IP65. Both designed for outdoor use.
The maximum wind speed the pantograph can still operate is 44.8 mph (8 Bft). The
maximum deflection of the Charge Pole at a wind speed of 89.5 mph (14 Bft) is 3.94
Inch.
The stability of the Charge Pole is calculated using the earthquake zone of Italy (S=12)
according to EN 1998.
It is recommended to provide good lighting around the Charge Pole to increase safety
and reduce misalignment.
It is recommended to indicate the maximum drive-through height (177.17 Inch) for
other traffic.
