SECTION 6 - Installation and Start-up
6.1 Receiving and installation
When the equipment is received, follow the directions for
unpacking and handling as directed in instructions attached to
the equipment. Be sure to keep equipment in an upright
position, unless measures have been taken to lay equipment
down.
The field discharge resistor assembly is probably shipped
separately for field installation on top of the equipment. The
resistor assembly is identified by a catalog number coinCiding
with that of the section on which it is to be mounted. Report any
equipment damage to the carrier immediately.
CAUTION: DE-ENERGIZE ALL EXISTING EQUIP-
MENT BEFORE INSTALLING NEW EQUIPMENT
6.1.1 Installing complete controller
equipment
Follow instructions provided with the equipment for
placement of the enclosure. Refer to the outline drawings,
details for incoming conduit and cable locations, and floor bolt
holes.
CAUTION: SEPARATELY SHIPPED FIELD DIS-
CHARGE RESISTOR MUST BE MOUNTED AND
WIRED TO CONTROLLER BEFORE ENERGIZING
CONTROLLER.
Refer to elementary diagrams and outline drawings for
identification and location of incoming power cable, motor cable,
field wire and control wire connections. After installation is
complete refer to the start-up procedure (6.2) in Section 6 prior
to energizing the equipment.
6.1.2 Installing field panels
For installing field panels, refer to Section 4.1 .2 entitled
"Starting Protection." Also check that the interconnecting wiring
between the field panel and the ac power switching device
(contactor or circuit breaker) is wired per the elementary
diagram for the field panel equipment. In case of trouble, it is
mandatory that this wiring be correct so that the field panel can
trip the motor off line by means of the ac power switching device.
Review the start-up procedure before energizing the equipment.
6.1.3 Component CR192 fLSPM
When the IlSPM is shipped separately, carefully unpack the
module and report any observable damage to the carrier.
Mounting the CR1921lSPM requires careful attention to the
following instructions.
1. Remove the face-plate assembly by loosening the
four (4) screws on the front of the IlSPM. The screws do not
need to be completely removed.
2. Carefully disconnect the ribbon cable from the face-
plate assembly. Disconnect the cable at the face-plate
assembly. A small screwdriver can be used to gently pry the
disconnect apart from tabs on each end of the disconnect.
Use the ejector tabs to disconnect the cable.
3. Carefully unstab the ground wire from the face-plate
assembly.
4. Mount the cable to the rear of the panel over the
cutout prepared for the IlSPM. See Figure 26.
5. Carefully re-connect the ribbon cable and the ground
wire to the face-plate assembly. Make sure the ejectors close
over the connector properly.
NOTE: DO NOT shift or skfNol the ribbon connector.
6. Re-mount the face-plate assembly to the case from the
front panel. (It may be necessary to further loosen the screws
before re-mounting.) Be certain all four screw latches engage
the IlSPM box. These can be inspected from the rear of the
unit.
NOTE: DO NOT let the face-plate assembly
dangle from the connecting wires.
Wire the IlSPM using either Figure 10 (ring type) or
Figure 23 (brush less) as a guide. Pay particular attention to
the connection of the CT. and C.PT. inputs to the IlSPM.
These inputs must be connected per Figures 10 and 23 for
proper power factor protection.
7. Field and exciter voltage inputs. The field voltage in-
puts (V
F
+ and V
F -)
and exciter voltage inputs (+VE and -VEl
must be connected to a separately supplied external resistor
assembly. Resistor assembly Cat. No. for field voltage input
only is 55B529836G3. Resistor assembly for field and exciter
voltage inputs is 558529836G4 (used when EXCITER
VOLTAGE CHECK PROTECTION and EXCITER VOLTAGE
DISPLAY options are supplied). These assemblies are sup-
plied automatically with the new CR192 IlSPM units. See
Figure 10.
WARNING: DO NOT ATTEMPT TO START THE
MOTOR WITHOUT THE EXTERNAL RESISTOR
ASSEMBLY WIRED IN WHEN USING
-C
THROUGH -F VERSIONS. SEVERE DAMAGE TO
THE CR192 IlSPM WILL RESULT IF THE EXTER-
NAL RESISTOR ASSEMBLY IS NOT PROPERLY
CONNECTED.
NOTE: The following paragraph applies to the
CR192 -E and -F versions only:
8. If voltage excursions occur outside the above ranges, a
provision is available that will allow the user to connect an
external stabilizing transformer for operation with severe con-
trol power voltage dips. The CR192 -E, and -F versions have
separate inputs for control power and power factor reference
