Warning — You must connect the drive’s protective conductor terminal, marked
with the earth symbol
, to a reliable system Protective Earth.
Warning — The drive’s connector strip terminals have hazardous voltages when
power is applied to the drive, and up to several minutes after power is removed.
Lower voltages may still be present for several minutes after power is removed.
During normal operation, these high voltage terminals must not be accessible to
the user.
Motor with Full Wave Rectifiers
Some Parker brake motors (BE, SM, SE, NeoMetric, and J series motors,
serial numbers greater than 010904xxxxx) contain full wave rectifiers, so
connection polarity is not an issue during installation.
Connecting the Brake Relay
1. Connect one red/blue brake wire (Parker Motor cable or equivalent) to
the BK terminal of the Motor connector on Aries models AR-01xx to
AR-13xx, or the Control connector on models AR-20xE and AR-30xE.
2. Connect the second red/blue brake wire (Parker Motor cable or
equivalent) to the 24V return on your power supply.
3. Connect the +24 VDC power supply to the second BK terminal of the
Motor connector on Aries models AR-01xx to AR-13xx, or the Control
connector on models AR-20xE and AR-30xE.
Figure 23 on page 37 shows a typical application—connecting a motor brake
to the relay terminals.
