2–21 Installation/Wiring
Terminal Block TB2
TB2 is located at the bottom of the Main Control Board. 0.37-7.5
kW (0.5-10 HP) A Frame drives have 18 positions. Remaining frame
sizes from 5.5 kW (7.5 HP) and up have 22 positions. The maximum
and minimum wire size accepted by TB2 is 2.1 and 0.30 mm
2 (14
and 22 AWG). Maximum torque for all terminals is 1.36 N-m (12
lb.-in.). Use Copper wire only. See Figures 2.1 and 2.3.
The recommended control signal wire is:
•
Belden 8760 (or equiv.)–0.750 mm 2 (18 AWG), twisted pair, shielded.
•
Belden 8770 (or equiv.)–0.750 mm 2 (18 AWG), 3 conductor, shielded.
•
Belden 9460 (or equiv.)–0.750 mm 2 (18 AWG), twisted pair, shielded.
Control Connections
If the drive control connections are to be linked to an electronic
circuit or device, the common or 0V line should, if possible, be
grounded at the device (source) end only.
Important: Signal Common – User speed reference signals are termi-
nated to logic common at TB2, terminal 3 or 4. This puts
the negative (or common) side of these signals at earth
ground potential. Control schemes must be examined for
possible conflicts with this type of grounding scheme.
Shield Termination – TE (True Earth)
The TE terminal block (not available on 0.37-7.5 kW (0.5-10 HP) A
Frame drives) provides a terminating point for signal wiring shields.
Refer to Figures 2.1 and 2.3 for location.
The maximum and minimum wire size accepted by this block is 2.1
and 0.30 mm
2 (14 and 22 AWG). Maximum torque is 1.36 N-m (12
lb.-in.). Use Copper wire Only and always separate control and
power cabling.
Cable Routing
If unshielded cable is used, control signal circuits should not run
parallel to motor cables or unfiltered supply cables with a spacing
less than 0.3 meters (1 foot). Cable tray metal dividers or separate
conduit should be used.
Important: When user installed control and signal wiring with an
insulation rating of less than 600V is used, this wiring
must be routed inside the drive enclosure such that it is
separated from any other wiring and uninsulated live parts.
