1.5 Connection Between IE-703002-MC and IE-703081-MC-EM1
The procedure for connecting the IE-703002-MC and IE-703081-MC-EM1 is described below.
Caution Connect carefully so as to avoid breaking or bending connector pins.
<1> Remove the pod covers (upper and lower) of the IE-703002-MC.
<2> Set the PGA socket lever of the IE-703081-MC-EM1 to the OPEN position.
<3> Connect the IE-703081-MC-EM1 to the PGA socket at the back of the IE-703002-MC pod.
When connecting, position the IE-703002-MC and the IE-703081-MC-EM1 so that they are horizontal.
<4> Set the PGA socket lever of the IE-703081-MC-EM1 to the CLOSE position.
<5> Fix the IE-703002-MC pod upper cover with nylon rivets.
An example of how to use the connector for target connection is shown below.
(1) When directly connecting device to target system (connector for target connection is not used).
(2) When mounting device by using connector for target connection.
