Control the mains contactor in such a way (connect Bb contacts
in series) that errors of both groups lead to circuit interruption!
Notes on Project Planning for
HCS02 as Supply Unit for
HMS/HMD
The HCS02.1E-W0054 and -W0070 types are allowed as supply units.
The HCS02.1E-W0012 and -W0028 types are not allowed.
HCS02 converters as supply units for HMS/HMD require:
●
Accessory HAS03 (to adjust different mounting depths)
●
Accessory HAS04 (capacitances C
y
at DC bus against ground)
●
Additional capacitors C
DC_ext
at the DC bus (external DC bus capaci‐
tance C
DCext
), if
–
the arithmetical mean of the output currents I
out
is greater than
I
out_cont
of the supplying device
–
the accumulated chronological sequences of the output currents
I
out
and the DC bus power P
DC
(superposition of the individual load
profiles) are greater than the allowed load profiles
Additional capacitance C
DC_ext
required for HCS02!
To determine the additionally required capacitance C
DC_ext
, the
following guide values apply when using an HLC01.1 DC bus ca‐
pacitor unit:
●
HMS01: Install 10 μF per A type current
●
HMD01: Install 20 μF per A type current
●
HMS02: No additional capacitance required
Arrangement of HCS02
Place HCS02 to the left of HMS01, HMS02 or HMD01.
Place the accessory HAS04 at the left of HCS02.
Place the DC bus capacitor unit HLC01.1 at the junction from
HCS02 to HMS01, HMS02 or HMD01.
Notes on Project Planning With
HCS02 as Supply Unit for KCU02
and KSM/KMS
The types HCS02.1E-W0054 and -W0070 are allowed as supply units for
KCU02 and KSM02/KMS02.
Additional capacitance C
DC_ext
required for HCS02!
For operation as supply unit with low load at the motor output
(P
out
≤ 10 % × P
DC_cont
; I
out
≤ 10 % × I
out_cont
, where P
out
refers to
KCU02/KSM02/KMS02 and P
DC_cont
to HCS02), the performance
data is available without additional capacitance C
DC_ext
at the DC
bus.
Use additional capacitors C
DC_ext
at the DC bus, when the load at
the motor output is higher.
When you use the DC bus capacitor unit HLC01.1, the following
guide value applies when you determine the additional capaci‐
tance C
DC_ext
:
●
50 μF per kW of installed continuous power KSM/KMS, thus
700 μF for a KCU02 operated at rated power.
