5 Connection and installation
5.1 General notes on installation
Strictly follow the safety regulations when installing!
Degree of protection IP20
Route all signal lines for the interfacing of digital inputs and contact monitoring separately.
You should in any case disconnect 230VAC (120VAC cULus) voltages from extra-low voltage
lines
(24V),
if these voltages are used in connection with the application.
The cable lengths for digital inputs and outputs must normally not exceed
30 m
.
If the cable lengths exceeds 30 m you must apply appropriate measures for fault exclusion
concerning impermissible overvoltage. Appropriate measures include e.g. lightning protection
for outdoor lines, overvoltage protection of the indoor system, protected routing of cables.
Only cULus:
The maximum cable length of
30 m
shall not be exceeded.
Measures concerning the electromagnetic compatibility (EMC)
The SMX100 module is intended for use in the drive environment and meets the EMC-
requirements mentioned above.
It is also assumed that the electromagnetic compatibility of the overall system is ensured by
application of appropriate measures.
Safety notes:
•
Electric power supply lines of the SMX100 and "discontinuous-action lines" of the power
converter must be isolated from each other.
•
Signal lines and power lines of the power converter must be routed through separate
cable ducts. The distance between the cable ducts should be minimum 10 mm.
•
Only shielded cables must be used to connect the position and speed sensors. The
signal transmission cable must be RS-485-standard compliant (lines twisted in pairs).
•
Care must be taken to ensure that the shielding is correctly connected in the 9-pin SUB-
D plugs of the position and speed sensors. Only metal or metal coated plugs are
permitted.
•
The shielding on the sensor side must comply with appropriate methods.
•
EMC-compliant installation of the power converter technology in the environment of the
SMX100 module must be assured. Special attention must be paid to the routing of
cables, the shielding of motor cables and the connection of the braking resistor. Strict
compliance with the installation instructions of the power converter manufacturer is
mandatory.
•
All contactors in the environment of the power converter must be equipped with
appropriate suppressor circuits.
•
Suitable measures to protect against overvoltages must be applied.
