Installation 4. Wiring Diagram

Optional Plug-in Module : ME-4201-NS96

Optional Plug-in Module : ME-0052-NS96

1. Do not bunch the digital input/output signal cables with the main circuit or power cables,

or install them close to each other. Keep the distance between the digital input/output

signal cables and the main circuit or power cables, and high voltage lines are shown

below, when they run parallel to each other.

2. Analog output signal cables should keep the distance from the other power cables and

input signal (VT, CT and auxiliary power) cables, and should not bunch them. And use
the shielded cables or twisted pair cables not to be affected the noise, serge and induction.
Also, the wiring cables are to be as short as possible.

3. In case of ME96NSR-MB with ME-4201-NS96, the ModBus interface and the analog

outputs do not have the insulation between them.
