4 Prepare for installation

4.1 Installation personnel

Read

Local authorization regulations for work with electrical equipment must always be obeyed.

The Site Commissioner is responsible for the installation of the eSite x10 and must be an approved user. The Site Commissioner is responsible for using correct cables to and from the eSite x10 and applicable MCBs or circuit breakers on the associated systems to prevent damage to the eSite x10.

4.2 Placement

Figure 4.1 shows a correct placement of the eSite x10 unit.

Figure 4.1. Placement of the eSite x10 unit (mm).

Placement of the eSite x10 unit must satisfy the following conditions.

• The cabinet that will host the eSite x10 must be safely anchored to the ground.

• The eSite x10 must be installed on a flat surface.

• The eSite x10 must be installed in a vertical position.

• The eSite x10 must not be installed closer than 3 m to a heating source, for example a genset exhaust pipe.

• The eSite x10 must not be installed in a position of constant exposure to dripping water.

• The eSite x10 must have a minimum of 440 mm of free space above the Mounting Frame to dock the Main Compartment.

• The eSite x10 Mounting Frame must be installed a minimum of 200 mm above solid ground to fit the connecting cables.

• The eSite x10 has a total height of 1 575 mm from top to bottom and requires a minimum space of 1935 mm with mounting space.

It is recommended to prevent direct sunlight from reaching the eSite x10 to maximize the efficiency.

4.3 Dimensions

Figure 4.2 shows the dimensions of the eSite x10 Main Compartment and the Mounting Frame.

Figure 4.2. Main Compartment dimensions (mm).

Mounting Frame dimensions (mm).

The Main Compartment is supplied in a box with the dimensions 1 168 mm × 620 mm × 457 mm. The RC Main Compartment has a weight of ~60 kg and the RSC Main Compartment has a weight of ~65 kg.

Dimensions for the Connection Compartment are shown in figure 4.3.

4.4 Prepare the work

Prepare the activities described below before you go to the installation site to prevent disruption of the installation.

• Make sure that you have access to the site.

• Make sure that a minimum of two persons are available for the installation.

• Make sure that a minimum of one person is an approved eSite user.

• Make sure that you have the correct cables for the installation, see section 4.6 Cable requirements.

• Make sure that all necessary tools are available, see section 6.1 Tools list for installation.

• Make sure that you have the equipment for the site commissioning, see section 8.2.1 Site Commissioning equipment.

4.5 Prepare the site

Prepare the site before you install the eSite x10.

• Dig down cable channels for cables to be drawn from the associated systems to the eSite x10.

• Make sure that the grounding system on the site is done in accordance with local and international standards.

• Make sure that the ground resistance is not more than 5 ohm.

• Measure resistance between all ground points and make sure that it is continuous.

4.6 Cable requirements

The current-carrying capacity changes if the insulation material, number of conductors in a power cable, installation procedures, grouping or ambient temperature changes. The power cable dimension in this document is only recommended by eSite Power Systems in these conditions:

• Multicore cables with PVC insulation.

• Cables with dual insulation.

• Maximum ambient air temperature 50 °C.

• Maximum cable length is 20 m.

• Maximum ground resistance is 5 ohm.

Cable use	Cable area	Nominal DC load (W)
Battery cable *	$100 \text{ mm}^2 - 250 \text{ A battery breaker}$ $70\text{ mm}^2 - 125\text{ A battery breaker}$	N/A
Ground cable	$50 \text{ mm}^2$	N/A
AC power cable (grid and genset)	$5 \times 6 \text{ mm}^2 \text{ (max 16 mm}^2)$	N/A
Solar power cable	$10 \text{ mm}^2 \text{ (max 25 mm}^2)$	N/A
Signal cable (screw terminals)	$0.5 \text{ mm}^2 - 2.5 \text{ mm}^2$	N/A
Customer load cable * *	$2.5 \text{ mm}^2$ $6 \text{ mm}^2$ $10 \text{ mm}^2$ $16 \text{ mm}^2$ $25 \text{ mm}^2$ $35 \text{ mm}^2$ $50 \text{ mm}^2$	$0-300$ $300-600$ $600-1000$ $1000-1500$ $1500-2000$ $2000-2500$ $2500-3000$

*Cable lugs are used for the connection of the battery bank. The dimension of the cable lug entrance depends on the battery cable. The dimension of the ring connector is Ø10 mm (see figure 4.4).

Figure 4.4. Dimension of power cable ring connector.

**The voltage drop from the point of supply to the load must not be more than 5 % of the nominal voltage during usual conditions for operations if the conditions above are obeyed. Conductors with a smaller or larger cross-sectional area than in the table above can be used if the conditions for installation and operation are different.
