1 For your safety
•
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.
•
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.
•
Use only extra-low voltages (max. 24 V DC).
