The password protection for Access Level 1 is now disabled.
The following Password Jumper subsection describes how password
protection for all access levels can be disabled by a hardware password
jumper.
Password Jumper
This subsection provides instructions for putting the password jumper in
place if you wish to operate the SEL-351P without password protection
or in the event that the passwords are lost or forgotten.
When the password jumper (JMP6-A) is ON (in place), password
protection is disabled. Figure 6 shows the general location of the
password jumper.
When the password jumper is OFF (removed/not in place), password
protection is enabled. This is how the SEL-351P ships from the factory.
Then the only way to disable password protection is with the PAS
command (see preceding
Disable Passwords subsection).
To change the password jumper position, carry out the following steps:
1. Deenergize the SEL-351P.
2. Disconnect all connections to the SEL-351P (remove GROUND
last).
3. Take SEL-351P to an ESD (Electrostatic Discharge) protected
work area.
4. Remove eight Phillips-head screws from front and left side panel
of SEL-351P.
5. Disconnect the ribbon cables from the front panel.
6. Remove front panel of SEL-351P.
7. Locate the jumper(s) to be changed (refer to Figure 6). Change
the jumper position.
8. Reconnect ribbon cables to front panel.
9. Replace eight Phillips-head screws in front and left side panel of
SEL-351P relay module.
10. Reconnect all connections to the SEL-351P (reconnect GROUND
first).
11. Reenergize the SEL-351P.
!
CAUTION: The relay module
contains devices sensitive to
Electrostatic Discharge (ESD).
When working on the relay
module with front or top cover
removed, work surfaces and
personnel must be properly
grounded or equipment
damage may result.
