Safety and Regulatory Notices
Using the system can cause danger and damage for life and limb of the oper-
ators or third parties, to the system itself or to other material assets. In addi-
tion to the manufacturer´s countermeasures, the operator must also take ap-
propriate countermeasures against danger due to residual energy. The per-
sonnel must be briefed about these dangers and the necessary countermeas-
ures during instruction.
The following general safety precautions must be observed during all phases
of operation of this instrument. Failure to comply with these precautions or
with specific warnings or instructions elsewhere in this manual violates safety
standards of design, manufacture, and intended use of the instrument.
Keysight Technologies assume no liability for the customer´s failure to comply
with these requirements. Please read the also Chapter 1 Section Intended
use.
Danger to life in case of misuse at the outputs.
The Scienlab Regenerative AC Emulator does not have its own insulation guard.
If the system emulates an electrical isolation against PE at the output, the local
installation regulations and guidelines must be observed.
This would be in the case of the emulation of an IT network in AC mode, or gen-
erally in DC mode.
Danger to life due to high voltages.
Some components are still supplied with voltage after switching off (wiring color or-
ange).
Before installation and upkeep, turn off and lock out all external voltage supplies.
Only disconnect or establish electrical connections in a voltage-free condition.
For models SL1214A and SL1215A, ensure model is in correct voltage range for
application before enabling system output.
Danger to life due to missing covers!
In case of misapplication, missing protective cover can lead to severe injury, burns or
death in the event of shock and arc flash.
Do not remove cover under load and not operate without cover in place.
After installation and upkeep, the previously removed protective cover must be
replaced.

Scienlab Regenerative AC Emulator –SL1200A Series –Operating Instructions
Depending on the set output voltage and current, the system sometimes releases
large amounts of energy at the output.
Touching the connection bars inside the system or the DUT terminals can occur life-
threatening body currents.
Never touch, connect, or disconnect the connecting lines to the DUT during ac-
tive operation.
Danger of arcing.
Residual voltage after switch-off.
In case of connected DUT, the output terminals can still carry voltages even after
switch-off of the system!
Measure the voltage at the outputs to ensure that they are voltage-free.
Danger to life due to charging or discharging batteries.
Batteries are sensitive to overloading/underloading and might explode or start burn-
ing. This can lead to danger for life and limb.
Therefore, a battery must be monitored by a battery management system (BMS).
EMC interferences possible!
The Scienlab Regenerative AC Emulator has an increased interference emission level
according to CISPR 11 at a rated input power of >20 kW. This can result in interfer-
ence with third party sensitive radio services in a distance up to 30 m.
For a rated input power of >20 kW, keep a distance min. 30 m to third party sen-
sitive radio services.
Hearing protection due to noise exposure in the operating area!
Noise level <85 dB(A) at a distance of 1 m from the front
It is recommended to wear hearing protection during operation.

Safety and monitoring devices
The system has monitoring devices that switch-off the system in case of
emergency. If additional systems are connected to the SL1200A Scienlab Re-
generative AC Emulator, it is recommended that the systems are integrated
into a higher-level safety device.
Main switch
•On the front side
•I ON: power supply switched on
•O OFF: power supply switched off, communication with the sys-
tem is maintained
•Trip: when emergency stop is triggered → system switches off,
main switch in position Trip
•Note: In the 0 OFF position, the main switch can be locked using
a padlock
Emergency stop push button
•On the front side
•Press: forces local emergency stop of the system
(Responds: see safety relay)
•Turn counterclockwise: unlocks
•Functional test of the emergency stop button: monthly
Key switch Test Release
•On the front side
•Used for enabling/disabling test
•OFF: test release withdrawn (output contactors and power stage
are blocked)
•ON: test release given; test may be started (e.g., acknowledged
by software)
Transformer circuit breaker for 24 V power supply (=EIN-1Q3)
(illustration similar)
•Behind the front panel (detachable)
•Circuit breaker for the circuit of 24 V power supply (logic path)
tapped upstream of the main switch
•O OFF: Circuit breaker has triggered → system is inactive; all
power and communication connections (logic path) are inactive,
switch on via main switch not possible.
•I ON: system can be switched on via main switch

Transformer circuit breaker for Measurement & Control Unit (MCU)
(=EIN-1Q2) (illustration similar)
•Behind the front panel (detachable)
•Circuit breaker for the circuit of MCU (logic path) tapped up-
stream of the main switch
Fuses behind the front panel (detachable)
•Fuses for:
•=CV2-1F1: 24 V control voltage
•=CV3-1F1: 12 V Ethernet switch
•=RPS1/3/5-1F1: power stages 1, 3 and 5
•=RPS2/4/6-1F1: power stages 2, 4 and 6 (only for SL1203A,
SL1213A, or SL1215A systems)
Fuse for the circuit between PE and output side neutral point (N’)
•Behind the front panel (detachable)
•=ACO-1F1: Fuse for the circuit between PE and output side neu-
tral point (N’) active in the emulated grounded grid.
•The fuse detects output-side earth faults (see Getting
Started document)
•0 OFF: Fuse has triggered → System is inactive
•I ON: Logic path MSE is active, main switch can be activated
Fuses inside the Output Box on the rear side of the system
•Fuses for:
•=ACO-2F1: AC Sense L1’
•=ACO-2F2: AC Sense L2’
•=ACO-2F3: AC Sense L3’
•=ACO-2F4: AC Sense N’

•=DCO-2F2: DC- Sense (optional)
Surge protection (=EIN-1F1)
•Inside the Input Box on the rear side
•Responds in the event of overvoltage (e. g. due to lightning)
•Reaction: Feedback signal is detected → undervoltage monitor-
ing reacts → the main switch cannot be activated (falls back to
position Trip)
•Consequence: Surge protection inlets must be changed (see
Chapter 6 Section Tripping of the Surge Protection), feedback
contact is reset
