Warning

The pow

er supplies are constructed in accordance with the safety requirements of IEC/EN/UL 60950-1, CSA-C22.2 No.

60950-1-03, UL508, CSA-C22.2 No. 14-95, EN60204, EN50178, EN61558-2-4, CSA C22.2 No. 213 (Class I and II, Division

2) and ANSI/ISA 12.12.01. They fulfil the requirements for CE-compatibility and carry the CE-mark and are UL & cUL
approved by CSA and UL.

The PRO-H Series built-in power supplies were designed especially for use in process automation and other industrial applications.
Components with dangerously high voltage and high stored energy are located in the device. However, these are
inaccessible. Failure to properly maintain the power supply can result in death, severe personal injury or substantial property
damage. The power supplies may only be installed and put into operation by qualified personnel. The
corresponding national regulations (e.g. UL, CSA, ANSI, VDE, DIN) must be observed. The successful and safe operation of
this power supply is dependent on proper storage, handling, installation and operation.

The potentiometer to adjust the output voltage is only allowed to be actuated using an insulated screwdriver, because
accidental contact may be made with parts inside the power supply carrying dangerous voltages.

Please observe following points before putting the device into operation:

• Read operating instructions thoroughly.

• That the mains connection has been carried out by a competent person and protection against electrical shock is

guaranteed!

• That the device can be disconnected outside the power supply in accordance with the regulations as in IEC/EN/UL/CSA
60950 or other national regulations.

• That the protective earth is connected.

• That the input wiring is sufficiently protected and dimensioned!

• That the output wiring is dimensioned according to the maximum output current or separately protected!

• Sufficient cooling is guaranteed!

• The temperature of the housing can become very high, depending on the ambient temperature and load.

Caution:

Risk of electrical shock and electrical discharge. The power supply must not be opened until at least 5 minutes after complete
disconnection of the mains.

Electrostatic sensitive device. Qualified and trained personnel only may open the power supply.

Attention: In case of non-observance or exceeding the mentioned limiting value of the data sheet, the function

and

electrical safety can be impaired and can destroy the power supply.

Before installation ensure that the main switch is switched off and prevented from being
switch

ed on again. In case of non-observance, touching of any live components or improper

dealing with this power supply can result in death or fatal injury.

Dang

er: Never work on power supplies if power is applied!

1. D

escription and construction

The PRO-H Series power supplies are built-in units. The mounting position has to fulfil the requirements for fireproof case according to UL60950,

EN 60950 or other appropriate national standard. The relevant UL regulations or equivalent national regulations must be observed during

IEC/
installation.

The PRO-H Series power supplies are designed for mounting on a DIN rail TS35 (DIN EN 50022-35x15/7.5) and for operation from 115 or
230VAC, 50/60Hz (Universal input voltage range for CP T SNT 70W 12V 6A, CP T SNT 90W 24V 3.8A and auto range for CP T SNT 140W
12V 12A, CP T SNT 180W 24V 7.5A, CP T SNT 180W 48V 4A, CP T SNT 360W 24V 15A, CP T SNT 360W 48V 7.5A, CP T SNT 600W 24V
25A and CP T SNT 600W 48V 12.5A single-phase systems.

The output voltage of the PRO-H Series power supplies is potential-free (floating), protected against short circuit and open circuit conditions (see
Fig 1.1, Fig 1.2 and Fig 1.3).

2. Installation

A sufficiently strong DIN-rail has to be provided. The correct mounting position for optimal cooling performance must be observed. Above and
below the power supply a minimum free space of 80mm [3.15in] is required and on each side of the power supply a minimum space of 50mm
[1.97in] is required which allows air convection. The air temperature measured 10mm [0.39in] below the power supply must not exceed the
specified values in the data sheet. Observe power derating above ambient temperatures of 40°C and at low line. (see Fig 4.1 and Fig 4.2)

2.1 Assembly

To fix unit on the DIN-rail, hook top part of clip on DIN-rail, push down- (see Fig 2.1) and inwards (see Fig 2.2) until you hear a clipping sound.

To remove the unit, pull the latch of the clip with the aid of an insulated flat head screwdriver (see Fig 2.3). When clip has cleared bottom DIN
rail remove the screwdriver from recess. Lift the unit off DIN-rail. See Fig 2.4.

Wall mounting or chassis mounting can be achieved by use of optional mounting brackets CP MB01 (1 bracket, see Fig. 6.1) for CP T SNT
(70W 12V 6A, 90W 24V 3.8A, 140W 12V 12A, and 180W xx) or CP MB02 (2 brackets, see Fig. 6.2 and Fig. 6.3) for CP T SNT (360W xx,
600W xx) . Remove the DIN-clips by removing the screw and place the mounting brackets in the same place as the DIN-clips.

2 Connecting cable

Only qualified personnel may carry out the installation. The devices are equipped with PCB plug connectors (CP T SNT 70W 12V

6A, CP T SNT 90W xx, CP T SNT 140W 12V 12A, CP T SNT 180W xx and CP T SNT 360W xx) or PCB terminals (CP T SNT 600W xx). This
reliable and easy-to-assemble connection method enables a fast connection of devices and a visible isolation of the electrical connection if
necessary.

2.2.1 Input (Fig. 5.1, Fig 5.2, Fig 5.3 and Fig. 5.4  Connector J1):

The 100-240VAC connection is made by using the L, N and
Suff

iciently dimensioned input wiring has to be ensured (see 2.2.1.1). A protective device (fuse, MCB, etc; see 2.2.1.2) and an easily
accessible isolating device for disconnecting the power supply from mains must be provided. The protective earth conductor has to be
connected.

If flexible wires are used the wires have to be terminated. (e.g. by using ferrules)

connections and has to be carried out in accordance with the local regulations.

Note: This unit contains an automatic input voltage selection switch. Do not change the input voltage from 110/115Vac to

230/240Vac without disconnecting the input supply line first.

2.2.2 Output (F

The 12VDC, 24VDC or 48VDC connection is made using the “+” and “-“ connections. All output terminals should be connected to the load.
Make sure that all output lines are dimensioned according to the maximum output current (see 2.2.1.1) or are separately protected! The wires
on the secondary side should have large cross sections in order to keep the voltage drops on these lines as low as possible.

To achieve a reliable and shockproof connection strip the connecting ends according 2.2.1.1. If flexible wires are used the wires have to be
terminated. (e.g. by using ferrules)

At the time of delivery, the output voltage is either 12VDC, 24VDC or 48VDC. The output voltage can be set (using an insulated screwdriver)
from 12 to 14VDC, 24 to 28VDC or 48 to 56VDC on the potentiometer (see Fig. 5.1, Fig. 5.2, Fig. 5.3 and Fig. 5.4).

The device is electronically protected against overload and short circuit. In the event of malfunction, the output voltage is limited to 20VDC for
12VDC units, 35VDC for 24VDC units or 60VDC for 48VDC units.

2.2.3 Signalling (Fig. 5.1, Fig 5.2, Fig 5.3 and Fig. 5.4  Connector J2):

The two DC-OK outputs are for enabling monitoring of the functions of the power supply. A floating signal contact (see Fig. 5.1, Fig 5.2, Fig 5.3
and Fig. 5.4  Connector J2, pin 6 & pin 7) and an active DC-OK signal (see Fig. 5.1, Fig 5.2, Fig 5.3 and Fig. 5.4  Connector J2, pin 5) are
available. The DC-OK LED also enables a visual evaluation of the function of the power supply directly on site.

2.2.3.1 Floating contacts (Fig. 5.1, Fig 5.2, Fig 5.3 and Fig. 5.4):

The floating signal contacts opens and signals a drop in the output voltage below: 12VDC units  between 9 and 11VDC; 24VDC units 
between 18 and 22VDC; 48VDC units  between 36 and 44VDC. Relay contacts are available at CP T SNT 70W 12V 6A and CP T SNT 90W

the 12VDC and 24 VDC units or 48VDC and current up to 0.5A for 48VDC units. For heavily inductive loads such as relay, a suitable protection
circuit (e.g. damping diode) is necessary.
