Operating Instructions
1 System Description
stages and the grounding conductor interconnections from the mains. In
the event of an emergency stop, the main switch switches the output to a
safe condition.
Figure 1: Two current paths of SL1200A
When switching the system off via the main switch, some components
connected in the logic chain (e. g. measurement and control unit (MCU),
switch and safety relay) are not switched off by the supply disconnecting
device and continue to be supplied with voltage (lines marked orange) to
maintain communication between system and operating software, even in
the event of an emergency stop. The logic path can be switched off via the
service switch (service switch/circuit breaker for motor protection). This
switch is located on the front behind the detachable panel. When the logic
path is switched off, the power path cannot be switched on.
Via the customer interface, the system can be configured as either a 1- to
3-phase AC source/sink or a DC source/sink (DC optional, -SDC option).
Channel switchover between AC and DC operation may only be performed
in load-free state. AC and DC operation use separate terminal blocks (DC
terminals only on -SDC option) (see documentation Getting Started
Guide).
System Arrangement
The SL1200A consists of two rack variants with three or six power stages;
both rack variants are available as low-voltage and high-voltage. The low-
voltage variants SL1201A
–
SL1203A are designed with an output voltage
of up to 600 V, an output current of up to 125 A, and an output power of
up to 90 kVA. The high-voltage variants SL1212A
–
1213A, however, pro-
vide an output voltage of up to 1,200 V, an output current of up to 65 A,
and an output power of up to 90 kVA.
Communication to both a control computer and the parallel-connected
systems is ensured by Ethernet interfaces.
