Earth
Check touch current (earth leakage current)! The total touch current is the sum
of the touch currents of all units. Safety limits – depending on the field of
application - apply for the allowed touch current!
EMC
The device is suitable for applications in industrial environment as well as in residential,
commercial and light industry environment without any restrictions.
For further details see datasheet.

(1) Use only power supplies from the same
Dimension Q-series.
(2) Adjust the output voltages of all power
supplies to approximately the same value
(±500mV). Otherwise, the DC-ok signal
might not work properly.
(3) A fuse (or diode) on the output is only
required if more than three units are
connected in parallel.
(4) Keep an installation clearance of 15mm
(left/right) between two power supplies and
avoid installing the power supplies on top of
each other.
(1) It is possible to connect as many units in
series as needed, providing the sum of the
output voltage does not exceed 150Vdc.
(2) Voltages with a potential above 60Vdc
are not SELV any more and can be
dangerous. Such voltages must be installed
with a protection against touching.
(3) For serial operation use power supplies
of the same type.
(4) Earthing of the output is required when
the sum of the output voltage is above
60Vdc.
(5) Keep an installation clearance of 15mm
(left/right) between two power supplies and
avoid installing the power supplies on top of
each other.

Use appropriate copper cables that are designed for an operating temperatures of 60°C (for ambient
up to 45°C) and 75°C (for ambient up to 60°C), minimum. Follow national installation codes and
regulations! Ensure that all strands of a stranded wire enter the terminal connection! Up to two
stranded wires with the same cross section are permitted in one connection point (except PE wire). Do
not use without PE (Ground) connection!
Air flow
Do not obstruct air flow! The unit is convection cooled. Ventilation grid must be kept free of any obstructions.
Keep installation clearances at higher ambient temperature and full load:
40mm on top, 20mm on the bottom, 5mm on the left and right side are recommended when loaded
permanently with full power. In case the adjacent device is a heat source, 15mm clearance are recommended.
(1) A phase to phase connection is allowed
as long as the supplying voltage is below
+15%

Fuse
(2) Use a fuse or a circuit breaker to protect

the N input. The N input is internally not
protected and is in this case connected to a
hot wire.
(1) The power supply will operate with a DC
input voltage.
(2) Use a battery or similar DC source.
(3) Connect +pole to L and –pole to N
+
(4) In case the –pole of the battery is not

-
the N terminal.
(5) Connect the ground terminal of the power
supply to a PE wire or to machine ground.
