Appendix E - REMOTE ALARM CONNECTIONS
Installation as well as all associated inspections should only be performed
by qualified persons:
These persons are qualified due to their special education and their practical
experiences, in particular with regard to the relevant legislation and standards, to
recognize the potential impact and hazards and to assess the necessary measures.
A changeover relay contact is provided (Terminals 12, 13 and 14 of the M507CE) to facilitate
reporting of an alarm condition at a point remote from the refrigerator.
In the ‘good’ condition the relay is energised, i.e. the Normally Open (NO) contact is closed and the
Normally Closed (NC) contact is open.
If the remote alarm is activated or there is a power failure the relay is released and the contact
changes over.
Connections to alarm or monitoring systems must not exceed 2 Amps at 50V AC/DC (resistive load)
for safety reasons.
