•
ALWAYS switch mains of input power OFF before connecting and disconnecting the
input voltage to the unit. If mains are not turned OFF, there is risk of explosion / severe
damage.
To guarantee sufficient convection cooling, keep a distance of 40 mm (1.57 inch)
•
above and 20 mm (0.79 inch) below the device as well as a lateral distance of 5 mm
(0.2 inch) to other units and if load less than 50%, lateral distance can be 0 mm. In
case the adjacent device is a heat source, the lateral distance will be 15 mm (0.6
inch).
•
Note that the enclosure of the device can become very hot depending on the surrounding
air temperature and load of the power supply. Risk of burns!
•
The main power must be turned off before connecting or disconnecting wires to the
terminals.
•
DO NOT insert any objects into the unit.
Hazardous voltages may be present for up to 5 minutes after the input mains voltage is
•
disconnected. Do not touch the unit during this time.
The power supplies are built in units and must be installed in a cabinet or room
•
(condensation free environment and indoor location) that is relatively free of conductive
contaminants.
