4.2.1 Operator’s safety
Danger!
All power terminals remain live up to 3 minutes after mains disconnection.
Labelling of the r.c.c.b. Meaning
AC-sensitive residual-current circuit breaker (RCCB, type AC)
Pulse-current sensitive residual-current circuit breaker (RCCB, type A)
All-current sensitive residual-current circuit breaker (RCCB, type B)
Definition In the following text “RCCB” is used for “residual-current circuit breaker”.
Protection of persons and
animals
DINVDE 0100 withresidual-current operatedprotective devices(RCCB):
The controllers are internally equipped with a mains rectifier. In the event of a short circuit to
frame a smooth DC fault current can block the activation of the AC sensitive or pulse-current
sensitive r.c.c.b. and thus eliminate the protective function for all units connected to this r.c.c.b.
We therefore recommend:
- ”Pulse-current sensitive r.c.c.b.” in systems with 820Xcontrollers (L1/N).
- ”All-currentsensitive r.c.c.b.” insystemswith821X/822X/824Xcontrollers (L1/L2/L3).
Rated fault current Please observe the rated fault current for the selection of the r.c.c.b.
The r.c.c.b. may be activated unintentionally by
capacitive leakage currents betweenthe cable screens (especiallywithlongscreenedmotor
cables),
simultaneousconnectionof severalcontrollers tothe mains,
using RFI filters.
Installation The r.c.c.b. must only be installed between the supplying mains and the controller.
Note about the use of
all-c urrent sensitive r.c .c.b.
All-currentsensitive r.c.c.b. are describedfor the first time inthe EuropeanstandardEN50178
(versionOctober1997). The EN50178 hasbeen harmonisedand has beeneffective since
October 1997. It replacesthe national standard VDE0160. The r.c.c.b. are also described inthe
IEC 755.
R.c.c.b. with a rated fault current of
- 30 mA are onlysuitable for systemswith820Xcontrollers,
- 300 mA are onlysuitable for systems with821X/822X/824Xcontrollers.
Electrical isolation /
protection against contact
The control inputs and outputs of all controllers are mains isolated. Please observe the terminal
description of the different controllers.
Replacement of defective
fuses
Replace defective fuses withthe prescribed type onlywhennovoltage isapplied.
For single drives, the controller carries a hazardousvoltage uptothree minutes after mains
disconnection.
In DC-bus operation, all controllers must be inhibited and separated from the mains.
Separate controller from the
mains
Make a safety disconnection between the controller and mains only via a contactor at the input side.
Ensure that all controllers connected to the DC-bus are inhibited.
