Using washers when mounting the DC link adapter
WARNING
Danger to life as a result of overheating and risk of fire when mounting the DC link adapter
without washers
When mounting the DC link adapter with combination screws M4x20 without using the
washers provided, can result in the DC link busbar overheating and causing a fire. This can
result in death or severe injury.
• Use one of the washers provided for each screw.
DC link adapters are supplied with washers, which are attached using a securing strap at the
inner hole of the DC link busbar. These washers must be used if a DC link adapter is
mounted on the left-hand side of a 150 to 300 mm wide module (one for each screw). It is
not permissible that they are used for other mounting scenarios.
