• LED and alarm contact output indicate the degradation
and life span of the surge protection circuits
• Easy maintenance thanks to discharge elements installed
on the element module

covered with insulation tubes.)
Surge protection type: Two-port SPD
Connection
• No interruption of signal even unplugging head element
• DIN rail mounting
• Transmission, power & grounding: M3 screw terminals
(torque 0.8 N·m)
45 (1.78)
• Alarm output: Euro Type Connector Terminal

or internal battery is drained. (Replace)
• PWR: Green LED
MODEL: MDW5ALW–B–[1]
ORDERING INFORMATION
Order the both pieces of this surge protector (the head
element and the base), respectively required for the use.
Order the pieces by separate only for replacement.
• Head element
ON when power is supplyed.
OFF when the base power circuit is in error.
Degradation judged: When the leakage current at the
voltage limiter exceeds approx. 100 μA
Life time judged: When the number of discharges of the
discharge element reaches the expected life span.
Alarm contact: Relay N.C contact
Code number: MDW5ALW-E
• Base
Code number: MDW5ALW-B-[1]
Specify a code from below for [1].
(e.g. MDW5ALW-B-R)
• Element error: ON when life span of the discharge
element has expired, the voltage limiter is degraded,
battery drain or element is removed.
• Base error: ON with power circuit error or power supply
failure

Grounding
*1. Be sure to use twisted-pair cables.
*2. No polarity.
*3. With shielded twisted-pair cables, connect the shield of the cable to the ‘3’ terminal of the M-Rester for floating, and with the ‘4’ terminal for grounding.
Follow instructions provided with the protected device whether ‘8’ and ‘9’ terminals should be connected or not.
However, if the shield terminal of the protected device is not isolated from NET A / B, DO NOT connect ‘8’ and ‘9’ terminals to the protected device.
