3.4. Adapting the grid
The HVC 100 or 150 Power Cabinet can be connected directly to the electrical grid or to an
existing customer low voltage power distribution cabinet. In both cases a 177 A (for the HVC
100) or 265 A (for the HVC 150), 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 and the HVC 150 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 directly to the electrical grid or to an existing
customer low voltage power distribution cabinet. In both cases a 2.17 A, 230 V AC, 50 Hz,
1P+PE connection is required. For each Dual Depot Charger Box, the 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
Dual Depot Charge Box must be taken into account during sizing of protection.
Maximum inrush current: 100 A < 5 ms.
