6 Electrical installation
CAUTION
De-energize the system!
The system could inadvertently start while you are connecting the devices.
b
Make sure that the entire system is disconnected from the power supply during
the electrical installation work.
NOTE
•
The MLG-2 complies with the EMC regulations for the industrial sector (Radio
Safety Class A). It may cause radio interference if used in a residential area.
•
Do not lay cables parallel to other cables, especially not to devices with a high
level of radiated emission, such as a frequency converter.
•
When using cables over 15 m in length, or in locations with a high level of interfer‐
ence, we recommend using a T-distributor in order to connect the sender and
receiver via a short synchronization cable wherever possible.
CAUTION
If you use the connecting cables with AWG 26 for the connection of the MLG-2, secure
the MLG-2 with a 1 A / 30 V DC fuse. Use the following table for other wire cross-sec‐
tion fuses.

6.1 Connect the sender and receiver
In the case of the MLG-2, the sender and receiver synchronize with each other electron‐
ically. This means that cabling is required between the sender and receiver.
You must connect the Sync_A connection on the sender to Sync_A on the receiver, and
Sync_B on the sender to Sync_B on the receiver.
To simplify the connections, T-connectors are available so that standard cables can be
used for the wiring (see "T-connector for MLG-2 connection", page 41).
