ABB PPC380AE01 HIEE300885R0001 medium and high voltage frequency conversion cabinet control unit
Extended function with accessories
Decoupling of power supply units with output currents > 20 A
Control of input voltages of CP-A RU with CP-A CM
The control module CP‑A CM indicates the presence of both input voltages of the CP‑A RU via LEDs
and energized output relays.
The threshold values for the output relays are adjustable separately per channel from 14 to 28 V. If, by
a fault (e.g. failure of a power supply, blown fuse), the voltage in a channel drops below the adjusted
threshold value, the corresponding output relay de‑energizes. The green LEDs “IN 1”, “IN 2” glow, if the
corresponding voltage exceeds the adjusted threshold value. The green LED “OUT” glows, if the output
voltage is higher than 3 V.
Examples of application with accessories
CP-A RU with CP-A CM for monitoring of two power supplies -
In case of fault: Fault signal
If both relays are de‑energized, the voltages of both channels are below the adjusted threshold value
(e.g. 20 V). This could mean, that both power supply units failed or are switched off, or that there is an
overload on the secondary side. Momentary de‑energization of the relays may be caused by inrush cur‑
rent of a connected load, during starting.
If one of the two relays de‑energizes, this can indicate that the primary power supply unit failed or is
switched off, and the redundant power supply is now supplying power to the load.
Examples of application with accessories
CP-A RU with CP-A CM for monitoring of one power supply -
In case of fault: Transfer to an alternative power supply
The following example of application shows transferring to an alternative power supply (in this example a
battery) after a failure in the primary power supply unit.
Installation
Mounting
The switch mode power supply can be snapped on a DIN rail
(TH 35-15 or TH 35-7.5 according to IEC/EN 60715) as shown
in the accompanying picture. For that the device is set with its
mounting rail slide on the upper edge of the mounting rail and
locked by lifting it downwards.
Demounting
Remove the switch mode power supply as shown in the accom‑
panying picture. For that the latching lever is pulled downwards by
means of the screwdriver. Then the device can be unhinged from
the mounting rail edge and removed.

Mounting position
The devices have to be mounted horizontally with the input terminals on
the bottom.
In order to ensure a sufficient convection, the minimum distance to other
modules must not be less than 80 mm in vertical direction and 10 mm in
horizontal direction.
Electrical connection of primary and secondary side
Connect the input terminals L and N. The protective earth conductor PE must be connected. Actuate
plug connector only when power is off. The installation must be executed acc. to EN 60950, provide a
suitable disconnecting device (e. g. line protection switch) in the supply line. The input side is protected
by an internal input fuse.
Rate the lines for the maximum output current or provide a separate fuse protection. We recommend to
choose the cable section as large as possible in order to minimize voltage drops. Observe the polarity.
Actuate plug connector only when power is off. The device is overload, short‑circuit and open‑circuit
proof. The secondary side of the power supply is electrically isolated from the input and internally not
earthed (SELV) and can therefore be earthed by the user according to the needs with L+ or L‑ (PELV)
Safety instructions and warnings
The device must be installed by qualified persons only and in accordance with the specific national
regulations (e. g. VDE, etc.).
The CP‑S 24/5.0 is a chassis‑mounted unit. It is maintenance‑free and does not contain any integral
setting elements and should therefore not be opend.
Before any installation, maintenance or modification work:
Disconnect the system from the supply network and protect against switching on!
Before start of operation the following must be ensured:
Connect to main according to the specific national regulations for class of protection I.
Power supply cables and unit must be sufficiently fused. A disconnecting device has to be provided
for the end product to disengage unit and supply cables from supply mains if required.
The protective earth conductor must be connected to the terminal PE.
Rate the output lines for the output current of the power supply and connect them with the correct
polarity.
In order to ensure sufficient air‑cooling the distance to the other devices has to be considered.
Screws at the enclosure are for internal grounding. Do not remove them! Do not connect cable!
Attention! Improper installation/operation may impair safety and cause operational difficulties or
destruction of the unit.
In operation pay attention to:
Do not modify the installation (primary and secondary side)! High current! Risk of electric arcs and
electric shock (danger to life)!
(Dis)connect the plug connector only when the power is off.
Risk of burns: Depending on the operation conditions the enclosure can become very hot.
If the internal fuse blows, most probably the device is defect. In this case, an examination of the
switch mode power supply by the manufacturer is necessary.
Attention! Danger to life!
Disconnect the system from the supply network before executing any works at the device and protect
against switching on! The power supply contains components with high stored energy and circuits with
high voltage! Do not introduce any objects into the unit and do not open the unit.
With some units of this range the output is capable of providing hazardous energy. Ensure that the
service personnel is protected against inadvertent contact with parts carrying energy.
