20 HLD-SLD PRESTO-ECOA OWNER’S MANUAL
ELECTRICAL SECTION
The standard power unit is pre-wired according to customer request. For supplied power other
than the original configuration, the power unit MUST be re-wired according to the Manufacturer’s
instruction sheet (see Figure 16). Service and Field wiring is the sole responsibility of the end
user. Presto-ECOA assumes no responsibility for incorrect installation or service wiring. The wir-
ing diagrams for the standard, and the more common options, are shown in Figures 7 - 14.
Install the power lines to conform to National Electrical Code (NEC) 480-22 and applicable local
codes.
NOTE
: If the available Power Supply is 208VAC/1PH/60Hz or 208VAC/3PH/60Hz, it is typically
necessary to supply booster transformers to ensure that the motor and motor starter contactors
receive the minimum necessary voltage.
Figure 15 shows the correct wiring diagrams for the booster transformers. Contact Presto-ECOA
Technical Service for additional information.
1. Standard Pendant Push Button Control Station:
The standard Control Station supplied with a SizzrDok series lift is a NEMA 4 weather proof
pendant type, with “UP” and “DN” momentary contact, “dead-man” type operation. The pendant
station is also mechanically interlocked, so that operation of one button locks-out operation of the
other.
