Installing and Connecting

3.3 ELECTRICAL INSTALLATION

The following information is a guide to the proper installation. Also comply with the applicable local
regulations for electrical installations.
DANGER!

The WEMOB-STATION demands high current and consequently high power for its
operation. Make sure that the demand requirements will be met by the electrical
infrastructure of the facilities;

Guards and installations must comply with national, state and local electrical
installation rules and regulations;

Make sure the supply line is disconnected before starting the connections;

The supply line voltage must be compatible with the WEMOB-STATION voltage
range;

The charging station must be connected to a protective earth (PE).
ATTENTION!

When flexible cables are used for the power and ground connections, it is
necessary to use suitable terminals at the cable ends;

All electrical connections must be well tightened so that there is no risk of sparking,
excessive heating or voltage drop in the circuits;

It is recommended to use copper conductors;

Ensure that during installation and use, the charging station is constantly and
properly connected to a protective earth (PE);

Do not share the grounding wiring with other equipment that operate with high
currents (e.g., welding machines, high power motors, etc.).

3.3.1 Grounding Requirements

The charging station must be connected to a protective earth (PE).
Do not use the neutral for grounding, but a specific conductor. The grounding resistance must be lower
than 100 Ω or lower than the maximum value defined in the applicable electrical installation standards, and
the voltage between neutral and earth, lower than 10 V.
Do not share the grounding wiring with other equipment that operate with high currents (e.g., welding
machines, high power motors, etc.).
ATTENTION!
Ensure that during installation and use, the charging station is constantly and properly
connected to a protective earth (PE).

3.3.2 Connecting the Power Supply

The WEMOB-STATION must be installed with a 5-wire 16 mm² multicore cable, with three cores for the
phases, one core for the neutral, and one core for the ground. The multicore cable must have an external
diameter of 18 to 25 mm to guarantee the sealing of the charging station through the cable gland.
The cables to the WEMOB-STATION must be connected to the points of the circuit breaker, neutral terminal
and ground bar, as shown in the figure:
