Insulation Blocks As shown in the following diagram, the function blocks of the E5AR-T/
ER-T are electrically insulated.
Functional insulation is provided between all of the following: <Inputs>,
<event inputs/voltage outputs/current outputs>, and <communica-
tions>.
Basic insulation is provided between all of the following: <Inputs/event
inputs/voltage outputs/current outputs/communications>, <relay
outputs>, and <transistor outputs>.
If reinforced insulation is required, input, event input, voltage output,
current output, and communications terminals must be connected to a
device that have no exposed charged parts and whose basic insulation
is suitable for the applicable maximum voltage of connected devices.
