and Signals
To avoid electric shock or damage to the equipment, always observe the
following precautions when connecting to the EXT I/O connector.
•
Always turn off the power to the instrument and to any devices to be con-
nected before making connections.
•
During operation, a wire becoming dislocated and contacting another
conductive object can be serious hazard. Ensure that the cable is
securely attached to the EXT I/O connector.
•
Ensure that devices and systems to be connected to the EXT I/O connec-
tor are properly isolated.
To avoid damage to the instrument, observe the following cautions:
• Do not apply voltage or current to the EXT I/O connector that exceeds their rat-
ings.
• When driving relays, be sure to install diodes to absorb counter-electromotive
force.
