3 Important safety notes
Make sure, that all of the following safety rules are fulfilled.
The device must only be installed by qualified personnel to make sure all applicable safety rules are fulfilled.
Additional safety rules and legal restrictions may apply depending on the country of operation.
•
Risk of electric shock!
Lethal high voltage is present inside the unit and at the terminals. Due to high voltage storage devices lethal voltages
may be present inside the unit and at the terminals if the unit is switched off or disconnected from supply voltage.
• The unit must not be operated if there is any damage (e.g. mechanical damage after transport).
• The unit is intended for use in dry and chemically and biologically inactive environment only. Keep water and humidity
away from the whole electrical assembly. Lethal voltages across the complete system can result from contact
between lamp and water. A separate protective earthing of the complete system is mandatory.
• Disconnect unit from mains before any maintenance operation.
Dangerous voltage may be present inside the unit energy storage devices even if the unit is disconnected from mains.
Wait at least 10 minutes after disconnecting the unit from mains voltage before starting any service actions.
• Repeated rapid switching might lead to a fault. Do not turn off and on the unit within less than 10 seconds.
• During ballast section start up, in case of lamp defects or due to wrong lamp wiring high voltages up to 1200V
eff
may
occur at the lamp terminals. This high voltage may be present for a couple of milliseconds until the internal protection
circuits shuts down the ballast. At each ballast restart, after any temporary disconnection from mains voltage, the
ballast will try to ignite the lamp once more, so again, high voltages may occur.
• The ballast does not provide galvanic insulation from mains at the lamp terminals.
• Harmful voltage occurs at the lamp terminals even if the ballast is in standby mode and the lamps are switched off.
• Never cut the lamp wires while the ballast is in operation.
Risk of serious injury or death!
• The load for the fault detecting contacts has to be kept within the limits specified in the datasheet. It is recommended
to use parallel operation of contacts instead of serial operation in case of summarizing fault detection.
•
The insulated contacts of the status relays do not provide protection against electric shock.
All wires of the error control loop have to be installed with appropriate protection against contact according to
applicable regulations. The wires of the error control loop must never be accessed from outside the earthed cabinet
without protection against contact. You may use insulation relays to access the control loop from outside the cabinet.
