Mains connection HCS02/HCS03 without mains contactor
You can do without mains contactors in the mains connection, if
without mains contactors you achieve the same safety for opera‐
tor protection as with mains contactors. For this purpose, the fol‐
lowing conditions must simultaneously apply to the respective ap‐
plication:
●
The safety-related requirements of the application allow this
●
The local safety regulations at the site of installation allow
this
●
HCS02 or HCS03 drive controllers with integrated 24V sup‐
ply (‑NNNV design) are used
–
Type of supply "central supply"
–
No components with DC bus short circuit protection de‐
vice ZKS (e.g. HLB) at the DC bus
–
Passive charging current limitation available via charg‐
ing resistor in drive controller (HCS02.1E-W0012…
0070; HCS03.1E-W0070…0150)
–
The 24V supply of the drive controllers (e.g. HMS,
HMD) operated at the same DC bus must have been
applied, before the mains voltage is switched on
Standard Design for HCS02 and HCS03 Drive Controllers
1)
Integration of the Bb contacts of other devices and configuration (see
"Configuration Rel 1 as Bb Contact" on page 145
)
2)
Take switching capacity of Bb contact into account (see Project Plan‐
ning Manual "Rexroth IndraDrive Control Sections"); CSB01.1N-FC
control sections have switch contacts with higher switching capacity
