Risk of fatal injury from interrupted protective earth conductor
– The protective earth conductor (yellow/green) must not be interrupted either outside or inside of
the device.
– The insulation of the protective earth conductor must not be damaged or removed.
•
In industrial facilities, the regulations BGV A3 “Electrical systems and equipment” of the Employer’s
Liability Insurance Association must be observed.
•
In schools and training facilities, the operation of power supply units must be responsibly monitored by
trained personnel.
•
Caution!
Capacitors in the device can still be charged even if the device has been disconnected from all power
sources.
•
When replacing fuses, use only prescribed fuses with the correct nominal current intensities.
•
Never switch on your power supply unit immediately if it is moved from a cold room to a warm one. The
condensate that forms can, under unfavourable conditions, damage your device. Leave the device
switched off until it has reached room temperature.
•
Risk of fatal injury from connecting power supply units in series
Contact voltages > 25 V DC are no longer permitted.
Voltages > 120 V DC can be fatal to the touch.
– Do not connect power sources in a row.
•
The ventilation slits of power supply units must not be covered. The devices must be placed on hard,
flame-resistant surfaces so that the air can enter the devices unhindered. The devices are primarily
cooled by convection.
•
When working under electrical voltage, use only expressly suitable tools.
•
Set the device up so that activation of switches and disconnectors is not rendered difficult.
•
Risk of fatal injury from electrical shock
Protect the outputs of the power supply units (output sockets/terminals) and cables connected to them
from direct contact.
– Use only cables with adequate insulation and/or electric strength.
– Use safety sockets with touch-safe contact points.
•
Safe operation of the device is no longer possible in the case of
– visible damage,
– faulty operation,
– inappropriate storage or
– inappropriate transport.
– Switch off the power immediately.
– Protect the device from being unintentionally turned on again.
•
Disconnect the power before making or breaking electrical connections.
