NOTE
No separate voltage supply is required for configuring using the
setup program as the device is supplied via the USB interface
(USB-powered). For a device in format 108H, 108Q, or 104, in this
case the standard digital outputs are activated and the digital
outputs of the options are deactivated.

Galvanic isolation
1. The voltage specifications correspond to the test voltages
(alternating voltage, rms values) according to EN 61010-
1:2011-07 for the type test. Type 702110 (format 132): 3000
V instead of 3510 V.
2. Functional galvanic isolation for the connection of SELV or
PELV circuits.
