Power Supply and Grounding

5
In order to assure a safe and error free operation, and to avoid severe
damage to system components, all system components* must be well
grounded to either a single earth or utility ground. This includes both
LinMot and all other control system components on the same ground bus.
Each system component* should be tied directly to the ground bus (star
pattern), rather than daisy chaining from component to component.
(LinMot motors are properly grounded through their power cables when
connected to LinMot drives.)
Power supply connectors must not be connected or disconnected
while DC voltage is present. Do not disconnect system components
until all LinMot drive LEDs have turned off. (Capacitors in the power
supply may not fully discharge for several minutes after input voltage has
been disconnected). Failure to observe these precautions may result in
severe damage to electronic components in LinMot motors and/or drives.
Do not switch Power Supply DC Voltage. All power supply switching
and E-Stop breaks should be done to the AC supply voltage of the power
supply. Failure to observe these precautions may result in severe
damage to the drive.
* Inside of the E1200 drive the PWR motor GND and PWR signal GND is connected together and to
the GND of the drive housing. It is recommended that the PWR motor GND is NOT grounded at
another place than inside of the drive to reduce circular currents.
