Intended usage
The equipment is intended to be used only as a variable voltage and current source or only as a variable current sink. Fur-
thermore it’s only intended to be used installed and operated in suitable equipment (19” rack or similar), together with a rigid,
non-retractable AC supply connection.
Typical application for a voltage source is DC power supply to any relevant user, including when used as battery charger to
test charge various battery types, and for current sinks the replacement of an ohmic resistor by an adjustable electronic DC
load in order to load relevant voltage and current sources of any type.
Additionally to the functionality of the equipment as source or sink of electrical energy on the DC side, all models in this series
are also so-called recuperating devices and thus not just drain energy on the AC side, but also source energy when being
sinks on the DC side. This is where the term “bidirectional” comes from. In sink mode the devices become energy recoverers,
but are not defined or considered as energy generation equipment.

Symbols and warnings on the device
Decal
Explanation
DANGER
RISK OF ELECTRIC
SHOCK
Disconnect all sources of
supply prior to servicing.
!
This warning is primarily related to the reconfiguration of the device on the DC termi
-
nal which, for safety reasons, requires to also cut the device from AC (external main
switch). The same applies to disconnection and reconnection of the AC terminal.
Capacitors on DC, stor-
ing voltage! Discharge
for 10 sec then ground
before working.
DANGER
!
Even after disconnection of the DC terminal from an external source there can still be
dangerous voltage potential present between the DC terminal poles and/or between
DC and the enclosure. For safety reasons the DC terminal must be short-circuited
after the capacitors have been discharged and it must also be grounded, i. e. con-
nected to PE.
WARNING
ELECTRICAL
HAZARDS
Authorized personnel
only.
!
There can always be a voltage potential on metallic, openly touchable parts on
electrical devices, though the voltage level may not be hazardous. Caution is still
advisable, as these potential can still cause mild electrical shocks or sparking.
WARNING
Read and understand the operat-
ing guide before using this device.
Non-adherence of the instructions
in the operating guide can result
in serious injury or death.
!
This is valid for any use of the device.
