adjustments, set the unit to "Parallel Use" mode to achieve load sharing. "Parallel Use" mode regulates the
output voltage so that the voltage at no load is approx. 4% higher than at nominal load. See also

The ambient temperature may not 60°C.
If more than three devices are connected in parallel, a fuse or circuit breaker with a rated current of 15A or
16A is required at each output. Alternatively a diode can be used.
Energize all devices simultaneously. It may also be necessary to ramp up and shut down the input power
(turn off for at least five seconds) if the output was overloaded or short-circuited and the required output
current is higher than the current of a device.
Restrictions: Keep a mounting distance of 15mm (left/right) between two power supplies and do not install
the power supplies above each other. In parallel mode power supplies should only be used in the standard
installation position (terminals on the underside of the device), not in other installation positions or under
other conditions that require a reduction in the output current (e.g. installation altitude ...).
Remember that leakage current, electromagnetic interference, inrush current and harmonics increase when
using multiple power supplies.
