I.6
I.3 ACCIDENT PROTECTION
The safety instructions provided in this Manual are included to prevent injury
to personnel (WARNINGS) or damage to equipment (CAUTIONS).
WARNING: High Voltage. BUS BAR's can have voltage ≥810V
dc
even after switching off
(capacitive voltage). Discharge Time approx. 6 Minutes.
WARNING: High Voltage. The recovery resistor is connected to the BUS BAR’s and can
have voltage ≥810V
dc
.
WARNING: do not touch recovery resistor during operation to avoid scalds.
CAUTION: it is recommended to disconnect the drive and the EMC filters to carry out the AC
Voltage Tests of EN 60204-1 (1997), par.19.4, in order to not damage the Y-type capacitors
between phases and ground. Moreover the DC voltage dielectric test required by EN 50178
(1997), product family standard, has been carried out in factory as a routine test. The DC
Insulation Resistance Tests of EN 60204-1 (1997), par.19.3, may be carried out without
disconnecting the drive and the EMC filters.
CAUTION: when required for an emergency stop, opening U2-V2-W2 pins and closing motor
phases to resistors, must be preceded by disabling the axis. The delay time must be at least
30 ms.
CAUTION: in case of repetitive switching on and off, waits 1 minute between off and on.
CAUTION: do not exceed the tightening torque of the table (but see proper data sheets for
the tightening torque of input capacitors and power modules and see section 2 of this manual
for the tightening torque of terminal blocks).
