5 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
These devices must be fused with a 1 A/30 V DC fuse.

5.1 MLG2 Pro electrical installation
For the MLG2 Pro, the sender and receiver synchronize with each other electronically.
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-distributors are available so that standard cables can be
used for the wiring (see "T-distributor for MLG2 Pro connection", page 46).
Sender connection: M12/5-pin, A-coded
