Multiple Drive Installations In a typical cabinet installation, a single mains line connects to a terminal bus
inside the cabinet. Then from the terminal bus, make individual connections
for Mains and Control power to the corresponding connector(s) on each
drive. Be sure to install fuses for each drive between the terminal bus and the
drive.
Tie each drive’s Protective Earth conductor terminal directly to the system
safety earth location as shown in Figure 20 (for models AR-01xx through AR-
13xx) or Figure 21 (for models AR-20xE and AR-30xE). Under normal
operation, no current should flow through the Protective Earth ground.
Safety Earth Connections
AR-01xx, AR-02xx, AR-04xx, AR-08xx, and AR-13xx
For multiple drive installations, Parker Hannifin recommends a single point or
“star” safety earth configuration. Figure 20 represents a typical star safety
earth connection for Aries models AR-01xx through AR-13xx.

AR-20xE and AR-30xE
Figure 21 represents a typical star safety earth connection for Aries models
AR-20xE and AR-30xE. Note that the AR-20xE and AR-30xE Motor/Power
connector has two Earth ground terminals⎯one for the motor and one for
input power. Be sure to use the VAC INPUT POWER terminal.
