3.2 I/O Terminals
To prevent electric shocks, do not apply a voltage exceeding 42Vpk
(DC + AC peak) between the ground of the BNC connectors insulated
from the enclosure and the enclosure.
Also, do not apply a voltage exceeding 42Vpk (DC + AC peak)
between the grounds of the BNC connector groups insulated from the
enclosure. "BNC connector groups" used here, indicates multiple BNC
connectors that are connected to a common ground.
If such a high voltage is applied, the internal voltage limiting elements
will try to reduce the voltage, but a too high voltage may cause the
product to be burned.

P.3-18
Do not apply a voltage from external to the output terminals.
This may damage the product.
Do not apply a voltage exceeding the maximum allowable voltage to
the input terminal. This may damage the product.
If a difference in potential exists between the ground of a BNC
connector insulated from the enclosure and the enclosure, do not
short-circuit the hot side of that BNC connector and the enclosure.
This may damage the product.
If a difference in potential exists between the grounds of BNC
connectors, do not short circuit these BNC connector grounds. This
may damage the product.
