3.4 Electrical Connections
3.4.1
!
CAUTION
Ensure that the voltage of the electric power supply is proper for the hoist or
trolley. The SMR2Q trolley is voltage reconnectable between 115V or 230V through a device called the
DPC (Dual Power Converter). Supplying the hoist with incorrect power supply could result in property
damage and/or injury. Refer to Section 3.4.7 for voltage change instructions.
3.4.2
!
CAUTION
Do NOT apply electronic soft-start control or voltage varying controls to the
SMR2Q trolley. Use of such devices may cause the motor brake and other electrical components to
malfunction.
3.4.3
!
DANGER
Before proceeding, ensure that the electrical supply for the hoist or trolley has
been de-energized (disconnected). Lock out and tag out in accordance with CSA Z460, “Control of
hazardous energy – Lockout and other methods”.
3.4.4
!
DANGER
To avoid a shock hazard, DO NOT perform ANY mechanical or electrical
maintenance on the trolley or hoist within 5 minutes of de-energizing (disconnecting) the trolley or hoist.
This time allows the internal VFD capacitor to safely discharge.
3.4.5
!
DANGER
Do Not remove power to the hoist or trolley during operation.
3.4.6
!
CAUTION
All SMR2Q trolleys are equiped with a VFD. The VFD is used to control the high
and low traversing speeds and accelereations. These speeds and accelerations come preset from the
factory, 80/13 feet per minute. Speed (frequency) parameters can be customized. Refer to Section
3.5.10 for trolley specific speed ranges and instructions and Section 3.5.11 for trolley specific
acceleration/deceleration ranges and instructions.
3.4.7 The following instructions apply to installations where an SEQ model electric hoist is installed on an
SMR2Q trolley. In this case the hoist and trolley are controlled by a pendant with four push buttons –
two for the hoist motion and two for the trolley motion.
Pendant Cord - The Pendant Cord directly connects to the trolley’s Connection Box using a Cable
Holder Assembly. Make this connection as follows:
1)
Refer to Figure 3-8 .
2)
With 1 inch of the outer cable insulation extending beyond the cable packing, insert the cable into
the Connection Box and screw together Cable Holder A and B.
3)
Install the Strain Relief Cable to the Cord Support on the Bar Holder.
4)
Inside the trolley’s Connection Box, insert the 6 pin and 3 pin pendant connectors (white) into the
CN13 connector and X21 connectors, respectively. Refer to the wiring diagram inside the control
cover and connect wires correctly.
5)
The spade terminals should be connected together (see Figure 3-9 )
Power Supply Cable Hoist Connection – The Power Supply Cable connects directly to the trolley's
Connection Box using Cable Holder Assembly. Make this connection as follows:
1)
Refer to
Figure 3-8
.
2)
With 1 inch of the outer cable insulation extending beyond the cable packing, insert the cable into
the Connection Box and screw together Cable Holder A and B.
3)
Refer to Figure 3-10 and connect the black and white(115V)/red(230V) wires to terminals 1 and 3
on the terminal strip inside the Connection Box. Connect the ground wire (solid green or green
with yellow stripe) to the ground terminal under the terminal strip.
NOTICE
The conductor on terminal 3 should be white for 115V and red for 230V. If this
is not the case, tape each end of the conductor with the appropriate color tape.
