Adapting The Grid - ABB HVC-R 100/150 V2 Installation Manual

3.4. Adapting the grid

The HVC 100 or 150 V2 Power Cabinet can be connected directly to the electrical grid or to
an existing customer low voltage power distribution cabinet. In both cases a 170 A (for the
HVC 100 V2) or 254 A (for the HVC 150 V2), 400 V AC, 50 Hz, 3P+PE connection to the
Power Cabinet is necessary that meets the following requirements:

Fuse (gG type) 3 x 315 A AC or 3 phase 285 A circuit breaker.

Main switch.

PE connected to the main PE rail.

The components used in the HVC 100 V2 and the HVC 150 V2 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 RCD in the range of 30 mA up to 300 mA. The Power Cabinet has
an integrated 300 mA RCD (Type A) for the power section.

Class 1 Surge Protection Device (SPD).
The Dual Depot Charge Box can be connected to the 230VAC output of the Power Cabinet
or: either directly to the electrical grid or to an existing customer low voltage power
distribution cabinet. In cases not involving power cabinet a 2.17 A, 230 V AC, 50 Hz, 1P+PE
connection is required. For each Dual Depot Charger Box connected to the distribution
board following requirements apply:

1 phase 16 A type A (30 mA) residual current circuit breaker.

Main switch.

PE connected to the main PE rail.

A TN-S earthing system. Possibly an extra 0.9 Ω earth electrode or local GND is
required, consult the grid owner.

Specifications of the following parts must be determined by your electrical engineer.
They depend on local laws, safety and electrical regulations:

Class 1 Surge Protection Device (SPD).

If circuit breaker is used in distribution cabinet, then specification of Inrush current of
Depot Charge Box must be taken into account during sizing of protection. Maximum
inrush current: 100 A < 5 ms.
