YASKAWA GPD-506V - Page 26

1-13
A disconnect device (circuit breaker, contactor, disconnect switch, etc.) should NOT be used as a
means of starting and stopping the drive or motor.
A disconnect device can be installed for emergency stop purposes, but when that disconnect device
is opened, there may be loss of electrical braking.
Figure 1-2 is a factory guideline for proper wiring practices and relative locations within the electrical
path from the line to the load. It does not imply what devices are needed for a particular application,
nor does it show what devices were shipped with a particular order. Therefore, disregard those
items in the diagram which are not being used in your installation. However, it is recommended that
an input or DC reactor be used with models GPD506V-A003 thru -A064 (CIMR-P5M20P41F thru
20151F), -B001 thru -B034 (40P41F thru 40151F) and CIMR-P5M51P51F thru 50451F when wired
to a source of 600 kVA or greater. Mount all optional power devices close to the drive, and keep
electrical connections as short as possible.

Figure 1-2. Customer Connection Diagram For Isolation Transformers, Input
Reactors, Input RFI Filters, DC Reactors, Output Reactors and Output RFI Filters
NOTES
1. Connect drive ground terminal or panel to
earth ground. Always use low impedance
paths and connections.
2. Mount input and output RFI filters physically as
close to the drive as possible (on the same
panel, if possible). Filters should have a solid
connection from filter ground terminal to the
cabinet ground point. If multiple input or
output RFI filters are used, they must be wired
in parallel.
3. Shield individual conductors with metallic
conduit, or use armored or shielded cable.
4. Connect output conduit, armored cable, or
shielded cable in a manner that allows it to act
as an unbroken shield from the drive panel to
the motor casing.
5. RF noise filter (different from RFI filter) part
no. 05P00325-0023 is a delta wye capacitor
network which is wired in parallel with the
drive input terminals. On the smaller drives
with die cast chassis, it must be mounted
externally. On the larger drives with sheet
metal chassis, it may be mounted inside the
area where the input power wiring enters the
drive. On units equipped with bypass, it may
be wired to the primary side of the circuit
breaker and mounted to the bypass panel or
sidewall.
