Installation manual
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.
