Requirements for Mounting
Requirements for the mounting location:
WARNING
Danger to life due to fire or explosion
Despite careful construction, electrical devices can cause fires. This can result in death or serious
injury.
• Do not mount the product in areas containing highly flammable materials or gases.
• Do not mount the product in potentially explosive atmospheres.
Optimum mounting location
The ambient temperature influences the tripping threshold of the circuit breakers for the
connected battery inverters. The higher the temperature, the earlier the circuit breakers will trip.
At high ambient temperatures, the derating function of the battery inverters inhibits premature
tripping of the circuit breakers.
• To ensure optimum operation, mount and install the Multicluster-Box and the battery
inverters at the same location.
Requirements:
☐ A solid, flat support surface must be available for mounting.
☐ The mounting location must be suitable for the weight and dimensions of the product (see
☐ The mounting location must be less than 2000 m above Mean Sea Level. If you would like to
use the Multicluster-Box at altitudes above 2000 m, contact Service (see Section 14,
page 36).
☐ The mounting location must not hinder access to disconnection devices.
☐ All local requirements concerning minimum passage widths and escape routes must be
observed.
☐ The mounting location should be freely and safely accessible at all times without the need for
any auxiliary equipment (such as scaffolding or lifting platforms). Non-fulfillment of these
criteria may restrict servicing.
☐ All ambient conditions must be met (see Section 12, page 30).
