WARNINGS
!
When electrical equipment is operated, certain parts of this equipment are automatically subjected to hazardous voltage.
Improper handling of the equipment may therefore result in fatal or severe personal injuries, as well as substantial damage
to property. Only qualified personnel should be allowed to work on or near this equipment. The equipment can function
correctly and safely only if it properly shipped, and stored, set up and installed in a workman-like manner
The R306 potentiometer must not be operated except with an insulated screwdriver conforming to DIN7437, since parts
subjected to hazardous voltage may be inadvertently touched. The equipment hood must not be removed for operating
adjusting elements until the mains voltage has been turned off and cannot be accidentally turned back on.
CAUTION
(ESD)
Reference to restrictions in compliance with the German national EMC act of September 18, 1998:
With regard to electromagnetic compatibility, this product complies with standards EN 50081-2 (emitted interference,
industrial environment) and EN 50082-2 (interference immunity, industrial environment).
With regard to emitted interference, this product is not suitable for applications in a residential environment.
Description and installation
Primary switched-mode power supply in IP65 degree of protection:
1. As a system load power supply for the ET200X programmable logic device:
2. As a stand-alone load voltage supply for general usage on industrial networks.
For connection to a single-phase 120 or 230 V, 50/60 Hz a.c. system.
Output voltage: +24 VDC, floating, short-circuit- and idling-proof.
The equipment is fitted with an internal circulating fan that cuts in as a function of temperature.

Mounting and installation notes
1. As a system power supply for the ET200X. The load power supply must always be mounted at the extreme right position on the
programmable logic controller. For an example refer to Figure 2 on page 6.
2. As a stand-alone load power supply. The load power supply can be operated at any mounting position. To preserve the high degree
of protection (IP65), the bus connectors have to be fitted with the "connector seal, IP65" accessory, order number 6EP1971 - 2CA00.
When installing the SITOP 24 V/10 A Power Supply, pay attention to the relevant DIN/VDE Regulations or national regulations.
The electrical connections (Figure 3, page 7) are accessible following removal of the terminal cover. To remove the terminal cover, undo 4
screws (Figure 4, page 7). Remove the terminal cover. Make sure that the shaped gasket is not damaged.
Prior to installation or maintenance work, turn off the main switch and immobilize it in the open position. In the event of failure to
comply with this safety regulation contact with live parts may result in lethal or severe personal injury.
Connection of the supply voltage (120/230 VAC) and of the optional bridge for the 120 V range must be performed in accordance with VDE
0100 and VDE 0160. A protective device (fuse) and a disconnecting device for isolating the power supply must be provided. For wiring
notes on power supplies connected in parallel refer to Figure 3 on page 7. Use only cables having an outer diameter of 4 to 10 mm that are
suitable for the ambient conditions concerned.
For operation of the power supply in the 120 V range, a bridge has to be connected between the two "AC120V-LINK" terminals. It must be
similar in design, in terms of cross-section and insulation, to the mains power leads. It must not be longer than 100 mm.
Caution: The optional bridge similarly conducts hazardous voltage.
