SITOP UPS1600 / UPS1100
108 Operating Instructions, 05.2014, C98130-A7628-A1-4-7629
6.1
UPS1600 input side connection
The UPS1600s are designed for connection to a 24 VDC power system. The 24 V supply
voltage must be SELV in accordance with EN60950-1 and EN50178.
Figure 6-2 Input side connection
The 24 V power supply is connected at the "IN+", and "IN-" ① terminals (see Figure 6-2
Input side connection (Page 108)).
The deployed cables must be suitable for temperatures of at least 90° C. (only for
applications for UL508)
Maximum cable length 3 m
6.2
UPS1600 output side connection
The output of the UPS1600 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 113))
Figure 6-3 Output-side connection
The output voltage is connected at the "OUT+" and "OUT–" ② terminals (see Figure 6-3
Output-side connection (Page 108)). Ensure that the output cables are dimensioned
correctly for the maximum output current rms value and fused accordingly.
The deployed cables must be suitable for temperatures of at least 90° C. (only for
applications for UL508)
