HVC 450 kW E-Bus Charger Installation Guide

3.3. Upgrade grid

The HVC 450 kW 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 576 A, 480 V AC, 60
Hz, 3P+GND connection is required. For each Power Cabinet (HVC 150 or HVC 150S) the
following requirements apply:

Fuse (type gG or fast-acting J type) 3 x 300 A AC or 3 phase 285 A circuit breaker.

Main switch.

GND connected to the main GND rail.

The components used in the HVC 450 kW E-Bus Charger are suited for a short circuit
capacity of 25 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.

Class 1 Surge Protection Device (SPD).

3.4. Location

The location of the HVC 450 kW E-Bus Charger must meet the following requirements:

The height is not more than 6561.68 ft above sea level.

The HVC 450 kW E-Bus Charger must not be immersed in water, or any other fluid.

The operational temperature of the HVC 450 kW 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 450 kW E-Bus Charger in areas where there is an
explosion hazard. You must provide information about the HVC 450 kW E-Bus Charger
to the fire brigade.

The protection rating of the housing of the Power Cabinet and ACS Control Module is
IP54 and designed for outdoor use.

The maximum wind speed the pantograph can still operate is 44.8 mph (8 Bft). The
maximum deflection of the ABB pole at a wind speed of 89.5 mph (14 Bft) is 3.94 Inch.

The stability of the ABB pole is calculated using the earthquake zone of Italy (S=12)
according to EN 1998.

It is recommended to provide good lighting around the ABB pole to increase safety and
reduce misalignment.

It is recommended to indicate the maximum drive-through height (177.17 Inch) for
other traffic.

Design and arrange the location around the HVC 450 kW E-Bus Charger on a matter
that the ABB pole and the Power Cabinet are hit by a vehicle is as small as possible.
For example, there can be installed bollards (see picture below).
