Geo Direct PWM Amplifier

Power On/Off Procedures 35

If the main bus power is removed (i.e. E-Stop condition), it is necessary to keep it off until the Bus LED

is turned off or dimmed completely. About 5-6 minutes. This ensures that the capacitors’ voltage has

dropped below 97 VAC and that the soft start circuitry has been armed.

Caution

Main bus power should Not be recycled within a time range of about ~

5 minutes.

Note

With the GPx201 and GPx301 models, it is possible to use the

external shunt resistor as a bleeding resistor to avoid the downtime

delay. Contact Delta Tau for details.
