(1) General
This unit employs many features previously unavailable in an industrial power supply. It has been designed
to withstand the high levels of interference found in heavy industry and has emission levels low enough for
it to be used in residential, commercial and light industrial environments.
The MCS5-400/24 has a high level of reserve power. This enables loads with significant inrush current to
be supported and will also ensure that circuit breakers will trip in event of short circuit.
A protective feature is provided which will take control as the unit approaches the power limit due the
overload or excessive temperature brought about by lack of ventilation.
NOTE: The unit is intended to be connected to star-connected network where the main voltage is 380 - 430
VAC (Max. Line to Earth voltage 250 V).
In order to take the best advantage of the
features that this power supply has to offer
and to ensure long term reliability for your
equipment, please read these instructions
carefully before installation and use. They
should be retained for future reference.

[4] Autorestart ON / OFF selection with jumper. Change is only allowed after 5 minutes of
disconnection from the mains. Use flat nose pliers to change the position. "OFF" means shut down
by over current or overvoltage or over temperature. Reset by disconnecting the mains for 2 min. "ON"
means continuous pulsated restart operation instead of shut down (factory default).

(4) Location
The power supply is cooled by natural convection. It is important to maintain clearance to other components
as much as possible to ensure best performance and long term stability. Top and bottom clearances should
be 100mm at minimum. Side clearance to other equipment should be 50mm or >100mm if that equipment
is heat generating. The ambient temperature should be measured on the underside of the unit. There will
be an increase of 25°C at the top. If natural convection is restricted, forced cooling should be used. Mounting
should comply with EN 60950-1 point 4.7 and 4.6.1. Protection class of the case IP20 (EN 60529).

(5) Mounting

The rail should be fixed solidly so that it cannot twist when mounting or removing the unit. Mounting
instructions [6], / Removing instructions [7].

Factory set, ready to use, check the connection diagrams for parallel and series connection.
(7) Loading capacity
The nominal current is 5 A but due to the nature of industrial loading, the power supply has been designed
to support loads with high inrush currents without damage or shutdown. Curve [9] shows the typical voltage
/ current curve. Decreasing part of the curve [9] shows the current limitation. Dashed line [10] shows the
pulse over loading limitation. Curve [11] shows the typical overload / temperature limit. Curves [12] to [15]
show the typical pulse loading characteristics with various base loads. Curve [16] shows unit's cabapility
to supply higher current by start-up. To ensure correct convection cooling, the unit must always be mounted
with rail horizontally.
(8) Parallel connection [17]
Up to 5 units may be connected in parallel. The open circuit voltage of each unit should be set to same
value. Accuracy of setting will determine how well the units share the load current. The gauge and lenght
of the cable between each power supply and the common point should be the same. Units should only be
used in parallel where the supply exceed 380 volts.

(9) Series connection
Up to 2 units may be connected in series to give either 48 VDC or +/-24 VDC. Check the connection
diagram [18].
(10) Using circuit breakers on the power supply output:
On the short-circuit, the power supply will trip, for example, the following ABB-STOTZ circuit breaker:
