Installation requirements
•
Power lines and STO control lines have to be routed in separate cables. This does
not apply to cables approved by SEW‑EURODRIVE specifically for this case of ap-
plication.
•
The line length between the safety controller and MOVIGEAR
®
may not exceed
100 m.
•
The wiring technology used must comply with EN 60204-1.
•
The STO control lines must be routed according to EMC guidelines and as follows:
– Outside an electrical installation space: Shielded cables must be routed per-
manently (fixed) and protected against external damage, or equivalent meas-
ures have to be taken.
– Inside an electrical installation space: Individual conductors can be routed.
– Adhere to the relevant regulations in force for the application.
•
Observe the values specified for safety components when designing the safety cir-
cuits.
•
The STO signal may not be used for feedback.
•
Observe the notes in the MOVIGEAR
®
operating instructions for EMC-compliant
installation.
It is important that the shielding of the STO control line is connected to the housing
at both ends.
•
Only use grounded voltage sources with safe disconnection (PELV) according to
VDE 0100 for all signal interfaces (SBus, digital inputs, digital output, etc.) of
MOVIGEAR
®
and all SBus stations.
According to EN 61131-2, the voltage between the outputs or between any output
and grounded parts may not exceed DC 60 V in case of a single fault in the
voltage supply.
•
When planning the installation, observe the technical data of MOVIGEAR
®
.
•
Do not use the DC 24 V output of MOVIGEAR
®
for safety-related applications with
MOVIGEAR
®
.
WARNING
No safety-related disconnection of the MOVIGEAR
®
drive unit.
Severe or fatal injuries.
•
Do not use the 24 V output for safety-related applications with MOVIGEAR
®
drive
units.
•
You may only jumper the STO input with 24 V when the MOVIGEAR
®
drive unit
is not used to fulfill any safety functions.
•
For safety-related applications with MOVIGEAR
®
drive units, you have to remove
the jumpers labeled "Caution, remove jumper for safety operation", see following
figures (jumpers are not installed in unit variants with STO plug connectors X5502
and X5503):
