POWER SUPPLY AND
ELECTRICAL CONNECTIONS
The hoist should be connected to a branch circuit which complies
with the requirements of the National Electrical Code and applicable
local codes.
It is recommended, especially for a single phase hoist with a (1)
horsepower motor (.75 Kilowatts), that a line of adequate capacity be
run directly from the power supply to the hoist to prevent problems
with low voltage and circuit overloads.
For grounding of the hoist, the power cord includes a grounding
conductor (green yellow, G-Y). Before connecting the hoist to the
power supply, check that the power to be used agrees with the
position of voltage change plug on the voltage change board. The
nominal hoist voltage rating corresponding to the voltage range
given on hoist identification plate is:

THREE PHASE HOIST
Unless ordered on a special basis, all single speed/dual voltage
(230/460-3-60, 220/380-3-50 and 220/415-3-50) hoists are factory
arranged to operate on 460-3-60 (or 380-3- 50 or 415-3-50).
VOLTAGE CHANGE BOARD
A voltage change board is provided to easily and quickly change
from 460 to 230 (or 380 to 220 or 415 to 220) volt operation. The
voltage change board shown in Figure 9 is located in the hoist as
shown in Figure 10. The voltage change board is color coded to
indicate high and low voltage connections. Connecting the 9 and
12 pin plugs into the "Red" voltage change board receptacles will
connect the hoist for high voltage (380-3-50, 415-3-50 or 460-3-60).
To change the hoist voltage to low voltage (208-3- 60, 220-3-50
or 230-3-60) simply remove the 9 and 12 pin plugs from the "Red"
receptacles and insert same into the "White" receptacles located on
the voltage change board. Be sure to make a notation of the new
hoist voltage on the tag attached to the power cord.

Figure 10. Location of Components
Both the voltage conversion board and PCB assembly are located under
back frame cover (1) for Models A-H and under motor housing cover (2) for
Models J-RRT.
PRINTED CONTACTOR BOARD
Some dual-voltage Lodestar hoists are equipped with a printed
circuit board assembly shown below in Figure 11. The board has
two-12 pin receptacles that correspond to either high or low voltage
operation. To change the hoist operating voltage from high voltage
(380-3-50, 415-3-50, or 460-3-60) to low voltage (208-3-60, 220-3-
50, or 230-3-60) simply remove the 12-pin plug from the receptacle
labeled "460V Motor" and insert the plug in the receptacle labeled
"230V Motor." Be sure to make a notation of the new hoist voltage
on the tag attached to the power cord.
