Installation
Check for damage during shipment prior to installation. Do not install or use a damaged product. Be
sure to maintain records of all accompanying product information. Contact your OZ Lifting Products
LLC® dealer if there are any problems or questions. Read and comply with all instructions and
warnings furnished with or attached to the product as applicable.
Wiring
Follow all electrical engineering and indoor wiring standards. Use of a qualified electrical contractor is
highly recommended for completing this portion of the installation.
NOTE: ̇ B efore connecting the power source to the hoist, confirm that the power source voltage
matches the applicable power source voltage for the product.
When using:
• A 110 V single phase power source - Install a plug with a ground pin or lead on the power cable.
• A 220 V power source - See a qualified electrical contractor.
• A single-phase power source from an engine-driven generator - Confirm that it has a rated output
of at least 1 kVA. Be sure to connect a grounding lead.

Setting the power cable/cord
When selecting a power cable for use with the OZ500EC, do not use an excessively thin power
cable or a power source that outputs reduced voltage. This may cause the hoist to fail or the cable to
overheat.
When using an extension cable, follow the guidelines below:
14AWG cable may be used up to a length of 165'
16AWG cable may be used up to a length of 100'
If the resistance of the cable between the power source and the OZ500EC and also that of other
electricity supply equipment is large, the voltage supplied to the hoist will fall markedly. As a result,
the OZ500EC may fail to function normally, or the power cable may overheat or burn out.
