WARNING Installing the device in a housing or a control cabinet The SITOP PSU2600 3ph power supply is a built-in device. It must be installed in a housing or control cabinet, to which only qualified personnel have access. The device can be mounted in a control cabinet on standard mounting rails (see Chapter...
A clearance of at least 50 mm should be maintained above and below the device (maximum depth of the cable duct, 50 mm). No space is required at the side. Output current as a function of the ambient temperature Figure 4-1 Output current in the standard mounting position SITOP PSU2600 3ph Manual, 01.2018, A5E39263454-2-76...
Particularly when installing on a vertically fastened standard mounting rail, additional measures may be required, e.g. to prevent the device from slipping on the rail. Figure 4-2 Mounting position 1 Figure 4-3 Mounting position 2 SITOP PSU2600 3ph Manual, 01.2018, A5E39263454-2-76...

Installation 5.1 Line-side connection The protective conductor of the line supply must be connected at the PE terminal. NOTICE Country-specific regulations must be observed when installing. SITOP PSU2600 3ph Manual, 01.2018, A5E39263454-2-76...
5.2 Output-side connection Output-side connection The SITOP PSU2600 3ph power supply provides at its output an isolated (= non-grounded) SELV output voltage (Safety Extra Low Voltage). The output of the power supply is no-load, overload and short-circuit proof. If an overload occurs, the electronic current limiting function limits the output current to a maximum value (see Section Technical data (Page 27)).
