Outputs Isolation - GE Multilin MIWII Instruction Manual

3.2 WIRING 3 HARDWARE

3.2.6 OUTPUTS ISOLATION

MII relays provide one trip contact, one alarm contact and four configurable contacts (option 1 and 2) sharing one
common.
An internal jumper, called Jx jumper, has been provided to allow splitting the four configurable outputs into two isolated
groups. In this case, the number of outputs is reduced to three.
Jx jumper is closed in the factory default configuration. (It is possible to order relays with Jx removed).
The figure shows the factory default configuration with Jx Jumper closed. It is located on the soldering part of the PCB
containing the inputs and outputs.

The Jx jumper is a tin-solder jumper easy to remove using a de-soldering tool.
The standard factory default output contact configuration consists of one group of four outputs, with the same common.
The figure below shows the configuration:
