• Connecting The MD6x To Model 6BX-E Outdoor Enclosure
Connect the green leadwire to the ground terminal inside the enclosure to ground through the enclosure’s outside ground
terminal.
If the enclosure does not have an inside ground terminal, connect the green leadwire directly to the outside ground wire pulled
inside the enclosure. Keep the ground wire as short as possible.

For wiring the MD6T, a cable gland is required. The packing of the cable gland must be separate from the body.
Choose an appropriate one for the environment in which the surge protector is used.

CABLE GLAND (Model MD6T)
The packing of the cable gland must be separate from the
body. Choose an appropriate one for the environment in
which the surge protector is used.
MAINTENANCE
Check surge protectors periodically. Many cases of light-
ning are ignored, and even lightning at a far distance often
causes inductive surges.
We recommend that you check your surge protector about
twice a year, before and after the rainy season. Check
whenever you experience a strong lightning occurrence.
Checking procedure is explained in the following:
■
CHECKING
WIRING
1) Make sure that wiring is done as instructed in the con-
nection diagram.
2) Make sure that the ground wire is connected to the enclo-
sure of the protected equipment.
3) Make sure that the ground wire is properly grounded to
earth.
DISCHARGE ELEMENT
1) Remove all wiring connected to the surge protector when
you test the module.
2) Check resistance across the following terminals on the
high resistance range of multimeter and confirm no con-
duction. The tester should show 10 MΩ or greater.
• MD6T
Terminals (1) – (2), Terminal (1) – Green wire,
(2) – Green wire
• MD6N and MD6P
Red wire – Black wire, Red wire – Green wire,
Black wire – Green wire
When connecting the multimeter across Terminals (1)
and (2), positive voltage must be applied to Terminal (1).
Likewise, for Red and Black wires, positive voltage must
be applied to the Red wire.
3) Confirm discharging across the same terminals with a
500V DC 1000 MΩ insulation tester. The tester should
show 20 MΩ or less.
4) If any of the above tests shows negative, replace the
surge protector.
