MD-LC2
MAINTENANCE
Check M-RESTER periodically. Many cases of lightning are
ignored, and even lightning at a far distance often causes
inductive surges.
We recommend that you check your M-RESTER 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:
n
CHECKING
WIRING
• Make sure that wiring is done as instructed in the con
-
nection diagram.
• Make sure that only the ground terminal (No. 8) of the
central MD-LC2 is grounded.
DISCHARGE ELEMENTS
Remove all wiring connected to M-RESTER when you test
the discharge elements.
• Check resistance across the following terminals on the
high resistance range of multimeter (infinite standard).
When measuring across (2) – (9) and (11) – (15), connect
the multimeter so that positive voltage is applied to (2) and
(11) terminal.
Terminals (2) – (9), (11) – (15), (2) – (8), (9) – (8),
(11) – (8), (15) – (8), (1) – (8), (10) – (8)
EXTERNAL DIMENSIONS
mm (inch)
• Check resistance across the terminal (1) – (10) on the
high resistance range of multimeter of 0.3V or less (infinite
standard).
• Check that discharging occurs across the same terminals
with a 500V DC insulation tester. (Indicator of the tester
reaches over-scale.)
• If any of the above tests shows negative, replace the M-
RESTER.
