Connecting The Drive Units - Siemens SIMOTION C Operating Instructions Manual

Setting power supply to the required supply voltage
Check whether the supply voltage selection switch is set correctly for your supply voltage.
The basic setting on the PS 307 is always 230 V. Proceed as follows to change the setting
for the supply voltage:
1. Remove the covering cap using a screwdriver.
2. Set the switch to the available supply voltage.
3. Refit the covering cap over the switch opening.
Reverse polarity protection
If the connection is correct and the power supply is switched on, the "5 VDC" LED is
illuminated green.
Note
Your module will not work in the case of reverse polarity. However, a built-in reverse polarity
protection will protect the electronics against damage.
Fuse
If a fault is present on the module, a built-in fuse protects the electronics against
consequential damage (e.g. fire). In this case, the module must be replaced.

Connecting the drive units

Connecting the connecting cable
Note the following:
Note
Only use shielded, twisted pair cables; the shield must be connected to the metallic or
metalized connector housing on the controller side. We recommend that you do not ground
the shield on the drive side. This is to separate low-frequency interferences from the analog
setpoint signal.
The pre-assembled cable available as an accessory provides the best possible immunity to
interference.
