*1. Be sure to use twisted-pair cables.
*2. No polarity.
*3. With shielded twisted-pair cables, connect the shield to the surge protector’s 'B' terminal.
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 NET A / B, DO NOT connect '2' terminal to the protected device.

•The M-RESTER is applicable to networꢀs which consist only of FTT-1ꢁA.
Not applicable to the ones connected to Linꢀ Power networꢀ.
• The maximum number of nodes connectable to the networꢀ segment is reduced by one
when one unit of M-RESTER is added.
• When the distance between nodes are relatively long (e.g. grouped and separated by cabinets),
install the M-RESTER by each group of devices. Insert the M-RESTER at the surge side of the networꢀ.
• For detailed information on the networꢀ, refer to LONWORKS FTT-1ꢁA Free Topology Transceiver
User’s Guide provided by Echelon.

(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.
