ƒ The capacitor module is approved exclusively for operation at
symmetrical mains. An operation at external conductor−earthed
mains is not permissible.
ƒ Observe the maximum permissible mains voltage. A higher voltage
destroys the capacitor module.
ƒ The discharge current to earth (PE) is > 3.5 mA AC or > 10 mA DC.
According to EN 50178, a fixed installation is required. The
PE connection must be made according to EN 50178.
ƒ All power connections are designed as pluggable and coded. The connectors
are part of the ECSZA000X0B capacitor module accessories set. It must be
ordered separately.
ƒ Installation of cables acc. to EN 60204−1.
ƒ The cables used must comply with the approvals required for the respective
application (e.g. VDE, UL, etc.).
