NOTES:
Midas S2 allows only one power source, 24 VDC or PoE. Failure to
l
observe this requirement may cause damage to the gas detection
system and will not be covered by the standard warranty
Earthing Requirements: If the Midas S2 unit's mounting bracket is not
l
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 or equivalent Ethernet cable is recommended. Please
ensure that your wiring avoids earth ground loops that may affect the
performance of your equipment.
Instrument grounding is required to ensure stable performance and to
l
limit the effects of radio frequency interference before installation.
Pull the terminal blocks to remove them from the connector module.
l
Connect the cables to the terminal blocks, referring to the relevant
l
wiring diagram. Strip and insert the end of each wire into the
corresponding terminal hole. Using a flat-blade terminal screwdriver,
tighten the terminal screw until the wire is secured. Use a ferrule on the
wire when necessary.
IMPORTANT: Do not over-tighten the terminal screw.
NOTE: When wiring the Midas S2 Transmitter to a controller, program the
controller for a 1-2 second delay before reporting to prevent false alarms.
