Iwatsu SY-8218 Instruction Manual page 8

Read the following safety information.
● Set the power switch on the front to STANDBY, turn off the main switch on the rear
before connecting or disconnecting the power cord.
Connecting or disconnecting the power cord while the power switch is ON may result in an
electric shock or failure.
● Insert the power supply plug into the receptacle firmly.
If not, an electric shock, fire, or failure may occur.
● When disconnecting the power cord from the receptacle, pull it out by grasping the
plug.
Do not pull on the cord itself, as doing so may damage the cord and could result in an
electric shock or fire.
● Before moving this product, confirm that external connection lines such as the
power cord and cables are removed.
The power cord and cable may be damaged causing a fire or electric shock.
● Never replace the fuse inside the main unit. Contact Iwatsu office or our sales
distributors for replacement.
● Use 3-core power cord in accordance with the power supply voltage.
If not, a fire may occur. In addition, if a 2-core power cord is used, a fire may occur.
Unless specified when purchasing this product, the power cord suitable for 100V system
(center voltage: 100V to 120V) is attached. If the power supply voltage is 200V system
(center voltage: 200V to 240V), use 3-core power cord suitable for 200V system (optional)
specified by Iwatsu (rating voltage: 250V).
● Do not apply an excessive voltage or current to the input connector (POWER INPUT
of the measurement POD).
If not, a fire, electric shock, damage to this product or a sample, or failure may occur.
The maximum allowable input voltage or current are as follows:
Input connector
Between P2-P1
Between S2-S1
POWER INPUT(SY-951 / SY-955)
(For details, see Chapter 8
●Do not ground the output connector or apply a voltage to the output connector.
Grounding it or applying a voltage to it may damage the ICs.
●Please check the sample parameters and the measurement conditions beforehand
before starting the measurement.
If you measure with incorrect sample parameters and measurement conditions, excessive
current will flow through the sample and the temperature of the core and windings may
rise.
It may lead to deterioration of the core or burning of the windings. Also, exceeding the
rated output of the power amplifier may result in failure of the power amplifier or failure of
this product.
