F N/C Wdog relay contact
1. The line earth terminal (C) is a noise-filtered neutral terminal.
If noise is a significant source of errors or electrical shocks are
a problem, connect the line earth terminal to the earth terminal
(D) and connect both to earth with a resistance of less than
100 Ohms.
2. To help prevent electrical shock, connect the earth terminal
(D) to earth with a resistance of less than 100 Ohms with a 14-
gauge wire or minimum cross section area of 2 mm
3. Terminals E and F for the CJ1W-PA205R are relay contacts
that close when Wdog is enabled. Refer to the BASIC Com-
mands in the Programming manual.
