HIGH VOLTAGE—To prevent risk of electric shock, make sure that
the terminal block covers are installed on the above inputs before
operation (see Figure 8-1).
Figure 8-1. Terminal Block Covers
These inputs and outputs are provided with 500 V of dielectric isolation from
chassis ground. In addition, these inputs/outputs are isolated from safety extra-
low voltage (SELV) circuits (such as serial communication, PC/104 circuits) by
optoisolators or transformers provided with double insulation and 3 kVac of
dielectric isolation.
