The requirements of individual installations vary significantly. It is not possible to give detailed instructions that apply for all sites. Consider these general factors when planning the layout of a machine charging site:

• Local rules and requirements:

  • Follow local rules for civil works, electrical installations, cable routing, and cable dimensioning.

  • The electrical designer is responsible for cable dimensioning. For help, contact Epiroc Service Support.

• When you determine cables length:

  • Add 1000 mm of extra supply power cable length above the installation surface.

  • For Satellites, add 1700 mm of extra control cable and communication cable length above the installation surface.

• How the units are moved to and within the installation site:

  • Do not tilt the charging power units more than 6 degrees.

  • Install units on a flat, level, and solid surface that can support their weight or on concrete foundations (prefabricated or made on-site).

  • Route cables above or below ground.

  • If using cable channels, make sure they are wide enough for all cables.

• Site-specific requirements and conditions:

  • If installing the charging power unit in a closed space, contact Epiroc Service Support to approve the location before installation.

  • If installing the charging power unit indoors, Make sure sufficient airflow to the unit.

  • If the temperature exceeds 30  °C for long periods, place the charging power unit in a ventilated shelter. Keep the display screen out of direct sunlight. For assistance, contact Epiroc Service Support.

  • The location of the main supply point supply grid main distribution board or one of the secondary substations.

  • Make sure an internet connection is available for Epiroc ChargEye and any OCPP backend system.

  • Use a SIM card or Ethernet (SuperCat 6/7 shielded) cables for your wide area network (WAN) router.

  • Make sure the charging power unit is accessible for maintenance without blocking traffic or movement in the charging area.

  • Make sure the charging points are easily accessible to users.

  • The maximum distance between the charging power unit and a charging point is 80 meters.

Mechanical Planning

The requirements of individual installations vary significantly. It is not possible to give detailed instructions that apply for all sites. Consider these general factors into the account the local rules and requirements on civil works, electrical installations, cable routing, and cable dimensioning.

Epiroc delivery includes the charging equipment and cabling inside the units. The steel base is the standard installation foundation for all the charger cabinets.

• For the footprints and clearances, see 5.3: Foot prints and clearance Charger 200, Charger 160 MV / Charger 320 and Charger 600.

• Consider the bending radius of cables, especially when installing units near walls.

• The cables to all units are always routed from below the unit:

  • Route AC mains power cables to the charging power unit from the front or the left side. See Section 4.2.1: AC Mains Power Cables to the Charging Power Unit.

  • Route connection cables to the charging points from behind or the right side of the charging power unit. See Section 4.2.2: Cabling Between the Charging Power Unit and DC Charging Points.

• To reduce the cable diameter:

  • Place the charging points as close to the charging power unit as possible.

  • Position the charging power unit approximately midway between the charging points connected to it.

• Make sure that the charging points are placed and oriented so that the charging cables easily reach the machine to be charged.

  • The maximum reach of a 7 m charging cable (nominal length) is approximately 6 m.

  • Rotate a single Satellite 45–60 degrees to maximize the operating area of the charging cable.

  • Rotate a double Satellite 90 degrees to provide maximum operating area for cables on both sides.

Electrical Planning

The Epiroc delivery includes the charging equipment and cabling inside the units. Cabling from the AC main power supply to the units, cabling between the units, and any other components are the customer responsibility.

AC Mains Power Cables to the Charging Power Unit

Phases 1–3 (L1, L2, L3) can be aluminum or copper wires. We recommend using copper wire for protective earth (PE).

Units Manufactured After 3/2023

When the AC supply terminal blocks of the cabinets are not jumpered:

• In single cabinet units, at maximum two AC mains power cables can be connected to one cabinet.

• In double and triple cabinet units, one AC mains power cable must be connected to each cabinet.

• If you want to install jumpers, Follow the specifications for units manufactured before 3/2023.

Units Manufactured Before 3/2023

• Jumpers can be removed on-site. If removed, follow the specifications for units manufactured after3/2023.

• When the AC supply terminal blocks of double cabinets are jumpered together, one AC mains power cable can be connected to one of the cabinets.

• When the AC supply terminal blocks of triple cabinets are jumpered together, one AC mains power cable can be connected to each of the end cabinets. No AC mains power cable is connected to the middle cabinet.

Cabling Between the Charging Power Unit and DC Charging

DC Output Power Cables

The dimensioning of the DC output power cable depends on the maximum output current of the charging point. Multiply the output current with the number of cabinets in the charging power unit.

The DC output power cable can be shielded or non-shielded. Non-shielded cables must have 5 wires (2 x DC+, 2 x DC-, and PE). Copper wires are recommended.

Indicative cable types for single Satellite (300 A)

• 2 x (4 x 35 mm² + PE) or 2 x (5 x 35 mm²)

• 4 x 50 mm² + PE or 5 x 50 mm²

Indicative cable types for double Satellites (300 A)

• 4 x (4 x 25 mm² + PE) or 4 x (5 x 25 mm²)

• 2 x (4 x 50 mm² + PE) or 2 x (5 x 50 mm²)

Control Cable

Use a 4 x 1.5 mm^² Cu control cable if the distance between the charging power unit and the charging point is up to 50 m. Use a 6 x 1.5 mm^² Cu control cable if the distance is more than 50 m.

For distances over 50 m, use two parallel auxiliary power wires (+24 V) and ground wires (0 V) to reduce voltage drop. Ground the cable shield at the charging power unit end.

Indicative cable type

• 7 x 1.5 mm² Cu cable

  • Control signal wire

  • Auxiliary power wire for the user interface of the satellite (+24 V)

  • Ground wire (GND, 0 V)

Communication Cable

Indicative cable type

• SuperCat 6/7 shielded Ethernet cable 4 x 2 x 0.25 mm²

The ethernet shield is grounded at one end only, either charging power unit or Satellite.

Connectivity to the Epiroc ChargEye and possible OCPP backend system requires an Internet connection, either with a SIM card in the control module of the master charging power unit or Ethernet cabling between your wide area network (WAN) router and the master charging power unit.
