3 Mains Connection and Grounding
Figure 1: Mains connection, grounding and overvoltage category (OVC)
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 protective earth PE.
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) . Daisy
chaining from component to component is forbidden.
Power supply connectors must not be connected or disconnected while DC voltage
is present.
(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.
Integral solid state short circuit protection does not provide branch circuit protection. Branch
circuit protection must be provided in accordance with the National Electrical Code /
Canadian Electrical Code, and any additional local codes.
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 power supply unit.
