Signaling
"Normal operation", i.e. the input voltage at the DC-UPS basic unit is higher than the set cut-in threshold. The loads are being fed by the line-side power supply. If a
expansion module is connected, it is fully charged. Under normal operation, the green LED (o.k.) is illuminated and relay contact X2.2 – X2.3 (o.k.) is closed.
">85% charge", i.e. capacitor is loaded more than 85% (available rest capacity dependent upon aging). The second green LED (Bat>85%) is illuminated and relay
contact X2.7 – X2.8 is closed. (second green LED off and relay contact X2.7 – X2.8 open (de-energized position when unit is disconnected) means : Bat<85%, i.e.
capacitor charge below 85%)
"Floating operation", i.e. the input voltage is lower than the set cut-in threshold. The loads are being supplied by the DC-UPS. In floating operation, the yellow LED
(Bat) is illuminated and relay contact X2.1 – X2.2 (Bat) closed (de-energized position when unit is disconnected).
Alarm signal "Buffering not ready": When the "Buffering not ready" signal is active, the red LED (Alarm) is illuminated and relay contact X2.4 – X2.5 (Alarm) closed
(de-energized position when unit is disconnected). Causes for the "Buffering not ready" state in normal operation are as follows: "OFF" operating state, defective
capacitors or capacitor voltage < 7V. The interval for polling the operating states ON/OFF, capacitors or capacitor voltage < 7V, and for activating the relevant signal
output is 20 s during normal operation. After the end of the failure the signal remains till to the next polling.
The "Alarm" signal in floating operation means that the capacitor voltage has dropped to <12V and automatic disconnection is imminent. When the floating operation
has been finished due to overload, short circuit, exhaustive discharge protection or buffering timeout, the red LED (Alarm) gets dark, but relay contact X2.4 – X2.5
remains closed. Load rating of relay contacts: 60V DC / 1A or 30V AC / 1A
USB:
The signals are additionally outputs via a PC-capable USB interface. They are each displayed in the shape of 5
characters of plain text. The assignment is shown in the table on the right. A tool for reading out and processing the
signals is available free of charge on the Internet at http://www.siemens.com/sitop-ups. This website also contains further
information about the interface.
Technical specification: The USB interface is according to specification 2.0, the communication runs only at full speed,
i.e. 12Mbit/s. The Interface will be supplied by the DC-UPS with +5V ("self-powered"), signal state output every 75ms ±
20%; data output 29ms ± 20%, pause 46ms ± 20%. The connection to the PC is made by means of a usual 4-wired
shielded USB-cable with a wave-resistance of 90Ohm, a USB Series"A" connector to the PC and a USB Series "B"
connector to the DC-UPS and a maximum length of 5m. The cable contains two 28 to 20 AWG "non-twisted" USB-supply
wires (VBUS and GND) and two 28 AWG "twisted pair" data wires (D+ and D-).
Pin assignment: Pin1: VBUS (+4.4V to +5.25V DC), transmit data on Pin2 (D-) and Pin3 (D+), Pin4: GND
Receiving data: Receive of the character "R" (Signal Remote Timerstart) starts the timer of the DC-UPS basic unit with
the set buffering time (table 2). After the set buffering time, floating operation ends or, during normal operation, the output
voltage is interrupted for 5 s if "disconnection" is set. Receipt of the character "S" (shutdown signal) starts the timer in the
DC-UPS basic unit with the set buffering time (table 2). After the set buffering time the DC-UPS basic unit is switched off
retentively. It is restarted by disconnecting the DC supply voltage for at least 1 s. In combination with a SITOP power
supply the line voltage has to be interrupted for approx. 10 s for a restart.

Installation Instructions
In order to guarantee effective cooling, the unit must be vertically installed such that the input and output terminals and the incoming air slots are at the bottom. A
clearance of at least 50 mm must be left above and below the unit. Assembly / disassembly see page 8.
To reduce EMI and thermal strain DC-UPS and capacitor modules should be installed at least 50cm away from commutating chokes! Interface (USB) and control leads
(ON/OFF control circuit) must not be laid directly in parallel to power leads or cables (especially leads between frequency converter and motor or frequency converter and
commutating choke).
To minimize EMI the distance to those leads should be at least 10cm.
If the device is to be used in a hazardous zone it must be installed in an enclosure with degree of protection IP54 or higher. This enclosure must comply with the
requirements of EN 60079-15.
Before commencing with the installation or any repair work, switch off the plant main switch and lock it in the "OFF" position. Please read the operating
instructions for SITOP power.
