If Power over Ethernet (PoE) is used to power
the device, then 24 VDC power must not also be
connected to the device, (or conversely if 24 VDC
is used to power the Midas
via the Ethernet port must not be applied). Failure
to observe this requirement may cause damage to
the gas detection system and will not be covered
by the standard warranty.
When connecting the wires ensure that the power
switch is in the off position.
Diagram 4-5 shows the terminal module layout
and terminal identification as well as the jumper
locations.
Note: Earthing Requirements
If the Midas

connected directly to a metal surface for
earthing purposes, an additional earth wire
will be required. Connect a wire via the
PG16 gland to the dedicated earth tag (screw
terminal) located on the bottom bracket
and connect the other end of the wire to a
dedicated external earthing point.
If Power over Ethernet (PoE) power supply
is being used, shielded CAT5 Ethernet cable
is recommended.
Please ensure that your wiring avoids earth
