6. INSTALLATION:
A. PRE--INSTALLATION CHECKS:
1.
Check for transit damage.
2.
Check that all external wiring is in good order.
3.
Check that the load chain is in good order.
4.
Check that all fasteners and joints are tight and secure.
5.
Check the capacity of the lifting unit and bottom block.
B. POWER SUPPLY SYSTEM:
To insure proper operation, to avoid damage to the hoist and electrical system, and to reduce the risk of
electrical shock or fire, the branch circuit supplying power to the hoist must:
1.
Effectively ground the hoist in accordance with the National Electrical Code and other applicable
codes. Proper grounding provides a path with the least resistance for the electrical current to travel
reducing the risk of electrical shock. The standard power cord is equipped with a three prong plug,
used with our 110V unit. Make sure that the receptacle opening that receives the longest prong is
properly grounded.
2.
Be in accordance with the National Electrical Code (ANST/NFPA-70) and applicable National,
State and Local codes.
3.
Include a disconnecting means capable of being locked in the ‘open’ position.
4.
Have ample capacity to prevent excessive voltage drop during starting and operation. When
determining the size of branch circuit components and conductors, special consideration should be
given to the starting current amps (approximately three times that shown on the hoist identification
plate) and the length of the conductors. As a minimum, the system should be rated for 20 amps
and the system should have #14 AWG or larger, wiring.
5.
Include slow blow type fuses or inverse trip time circuit breakers to permit the hoist to start and
accelerate the load.
Failure to properly ground the hoist presents the danger of electric shock.
To avoid injury:
Permanently ground the hoist as instructed in this manual.
Failure to provide a proper power supply system for the hoist may cause hoist damage and
offers the potential for a fire.
To avoid injury:
Provide the hoist with a 20 amp, minimum, over current protected power
supply per the National Electrical Code (ANSI/NFPA 70) and applicable local codes as
instructed in this manual.
C. CONNECTION TO THE ELECTRICAL SUPPLY:
An adequate supply system is required along the total length of travel (where appropriate). The supply
voltage and frequency at which the hoist operates, is marked on the motor rating plate. It is imperative to
check before connecting the unit that these figures correspond with those of the supply voltage.
