Alarm Contact
The incubator can be connected to an on-site, external alarm system (such as a private branch
telephone exchange, a facility monitoring system, visual or audible alarm indicators). For this
purpose, the devices come with a pre-wired potential-free alarm contact (item 3 in

loop or the incubator's electrical circuits or hardware.

AC Power Socket

The incubator is connected to the AC supply mains via the socket (item 4 in
which accepts a power cord with an IEC standard plug.

Fuses

Two 16 A slow-blow fuses mounted on the incubator's main electronic circuit board protect
internal circuitry from the impact of excessive power consumption.
