3. Assembly

3.1. Residual risks

Danger to life due to fire or explosion
Fire caused by flammable or explosive material near the device may result in serious injury

  • Do not install the device in potentially explosive atmospheres or in the vicinity of highly flammable substances.

Property damage caused by gases that react aggressively to surfaces in conjunction with weather-related humidity.

  • The housing of the device can be severely damaged by gases in conjunction with weather-related humidity. (e. g. ammonia, sulphur).

    1. If the device is exposed to gases, it must be installed in a visible location.

    2. Carry out regular visual inspections.

    3. Remove moisture from the housing immediately.

    4. Ensure sufficient ventilation at the installation site.

    5. Remove soiling immediately, especially from ventilation systems.

→ In the event of non-compliance, material damage to the device is not covered by the warranty.

Access by maintenance personnel in case of service

  • Additional costs arising from unfavorable structural or installation conditions will be charged to the customer.

3.2. Foundation

  • We recommend preparing a foundation on site for the assembly of the inverter rack.

  • This foundation must be designed by the customer, taking into account the statics.

  • Please refer to the following image for the connection drilling diagrams.

drill markings
Figure 2. Drilling pattern

3.3. Ground anchor

We recommend fastening the inverter rack using ground anchors. Please use the enclosed ground anchors (list item 11 in the parts list: ZUS791).
(Hilti bolt anchor HST3-R M16 x 135 35/15 #2105876)
Please also observe the manufacturer’s setting instructions.

Please also note the torque of the bolt anchor (ZUS791).
The recommended torque is 110 Nm.
