•
The 24VDC supply must be protected with a 1AT fuse.
•
The +24V supply must not be connected / disconnected when voltage is present. The
DC supply must not be switched on the secondary side of the power supply unit.
•
It is recommended to connect pin 6 (AGND) to the reference ground of the analogue
input of the drive - in case of LinMot drives pin X4.1. realise connection as close to the
drive as possible to avoid potential differences compared to the drive GND.
•
External EMC circuitry: a ceramic capacitor 100nF / 50V can optionally be soldered
between pin 4 and pin 5 on the evaluation electronics to reduce conducted interference.
Bridges from Supply Ground and Signal Ground
•
PIN 4 (power -) and PIN 1 (supply GND) are internally galvanically isolated and must
not be connected to each other.
