Tinning wire ends may cause contact failure
and therefore is not recommended.

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
1. WIRING
• Make sure that wiring is done as instructed in the con-
nection diagram.
2. DISCHARGE ELEMENT
Approximate checking can be conducted as following.
• Shortcircuit test
1) Remove all cables connected to the MDCAT-SPE.
2) Remove also the shortcircuit bar.
3) Check resistance across the following terminals on the
high resistance range of multimeter and confirm no con-
duction. (The meter will indicate the same value as it
will show when these terminals are open.)
(1)-G, (2)-G, (3)-G
4) Then, apply ±60V DC across the following terminals and
measure leakage current to show ≤ 5µA. If a voltage gen-
erator is not available, check resistance with a multim-
eter and confirm no conduction. (Use of a voltage genera-
tor is strongly recommended.)
• Discharging test
1) Check that discharging occurs across the following termi-
nals with a ±500V DC 1000 MΩ insulation tester.
(The tester shows ≤ 20MΩ.)
(1)-G, (2)-G, (3)-G
