7.3 - MS-Com Password
This password is requested anytime the user wants to send to the relay a setting parameters
modification or to issue a command through the relay itself using the managing software MSCom.
The user can decide whether inserting his own password (see MS-Com Operational Manual) or
keeping the password disabled just clicking on the OK button when the password is requested.
8. Maintenance
No maintenance is required. In case of malfunctioning please contact Microelettrica Scientifica Service
or the local Authorised Dealer mentioning the relay's Serial No reported in the label on relays enclosure.
9. Power Frequency Insulation Test
Every relay individually undergoes a factory insulation test according to IEC255-5 standard at
2 kV, 50 Hz 1min. Insulation test should not be repeated as it unusefully stresses the dielectrics.
When doing the insulation test, the terminals relevant to serial output, digital inputs and RTD input must
always be short circuited to ground. When relays are mounted in switchboards or relay boards that
have to undergo the insulation tests, the relay should be isolated. This is extremely important as
discharges eventually tacking place in other parts or components of the board can severely damage the
relays or cause damages, not immediately evident to the electronic components.
