6.0 THE ELECTRICAL SYSTEM

6.1 Description

The electrical system provides control of all table functions and is comprised of a power cord,
an on/off circuit-breaker switch, wire harnesses, a power supply, a controller circuit, a hand
pendant, floor lock jackscrew-actuators, and various electromechanical actuators. Electric
motor-driven lead-screw actuators manipulate the table height, lateral roll and trendelenburg
functions. The input power requirement is 100 VAC 50/60Hz, 4 Amp, 120 VAC 60Hz, 4 Amp
or 230 VAC 50Hz, 2 Amp, 10%/6 minute duty cycle as indicated on the serial number label.

Refer to 6875 hana Surgery Table Electrical Interconnect Diagram in section 11.2 for details
of the electrical system.
The primary components of the electrical control system are contained in the power supply
box at the head end of the table.

6.2 On/Off Power Switch

An illuminated on/off power switch and circuit breaker is located on the head end of the table.
When illuminated, it indicates that the table is plugged into a live electrical Hospital Grade AC
outlet and the power is on. (When the table is turned on using battery power, this switch will
not illuminate). This switch also serves as a circuit breaker. In the event of an overload
condition this switch will trip off. To reset, push to the off position and then the on position.

6.3 Component Circuit Breakers

The electrical system includes individual component 24-VDC circuit breakers located at the
head end of the table. If a short circuit occurs in the low voltage circuit, the breaker will trip
as indicated by a button protruding from the access hole. To reset, press the button in and
release.
WARNING:
Determine the source of the overload prior to resetting this switch. If unable to
determine and fix the source of failure, contact Mizuho OSI for additional support.
