Guideline for electrical installation

m
A A
If these guidelines are not followed, sufficient personal safety and interference
immunity cannot be ensured.
It is also mandatory to comply with the corresponding locally applicable electrical
installation requirements.

ra
If the cables have to be installed in the same cable tray, the following
personal safety: possibilities exist
All electrical circuits must be routed in a way that is protected from external
mechanical damage.

ag
EMC = Electromagnetic Compatibility
B - observe a minimum distance of 5 cm (preferably use metal cable trays). B

1. separation of signal lines from power-voltage lines < 500 VAC

di
Cables with digital signal lines for direct current and cables with shielded analog
signal lines should preferably be installed in separate cable trays from those for digital signal lines for direct current,

- Separate the cable groups with a metallic partition. The cable trays and the
partition must be electrically connected (for reasons of electromagnetic
interference and lightning strike protection).

2. separation of signal lines from power-voltage lines > 500 VAC
C C

Digital signal lines, analog signal lines and data transmission cables must be separated from
power-voltage cables > 500 VAC to 1000 VAC by a minimum distance of 10 cm, and from transducer transducer

ui
power-voltage cables > 1 kVAC by a distance greater than 30 cm, preferably in separate
cable trays.

1) Only if specified in the schematic (shielding connected at both ends). If the shielding is
connected at both ends, a voltage equalization conductor may possibly have to be provided,

rc
specially in case of greater distances or differing power supplies.

2) If a capacitive shielding connection is used at the MCR unit, the shielding must not be

D no separate voltage equalization conductor is required. D
Analog signal lines must be installed with shielded cable. Connect the shielding according to
the sketch, at one end or both, depending on what is specified in the schematic. It is ci
preferable to use cable types with copper braid shielding. The inner conductors must be in
twisted pairs for the lead and return signal conductors.

shielding connection
Also on the motor side, the shield must be connected as short as possible to the chassis
(earth grounding connection). If the shield is only connected on the cabinet side to earth,
high emissions can be caused. If the motor lines are switched e. g. by a safety switch, the
shield must be wired over these elements as short as possible. If this is not possible,
exeptionally the shield can be connected on both sides to the chassis, because only the
radiation damages have to be blocked.
