Cross wiring
Grounding
≤ 100Ω
*1. Cross wire to the surge protector’s ‘G’ terminal when grounding the shield wire.
If the shield wire is not to be grounded, connect it to ‘B’ terminal.
*2. Follow instructions provided with the protected device whether ‘2’ terminal
should be connected or not. However, if the shield terminal of the protected
device is not isolated from PA BUS, DO NOT connect ‘2’ terminal to the
protected device.

Crossover Wire
*1. Fieldbus devices complying with IEC 61158-2 operate by a supply voltage between
9V and 32V DC.
Take the MDP-PA’s internal series resistance into consideration when determining the
cable distance if there is a large current flow on the bus line.
When the distance between nodes are relatively long (e.g. grouped and separated by cabinets),
install the MDP-PA by each group of devices. Insert the MDP-PA at the surge side of the network.
For detailed information on the network, refer to that provided by PROFIBUS International or
Fieldbus Foundation.

GROUNDING
(100 ohms or less)
CROSSOVER WIRE
A crossover wire between M-RESTER ground and the ground or
metallic housing of the equipment is required for protection.
If the protected equipment has no ground terminal, ground the
M-RESTER only.
When the M-RESTER is mounted with DIN Rail Mounting Adapter,
connect the grounding wire to the mounting screw of the M-RESTER.
