Electrical Installation
Access for the electrical wires to the terminal module is made via the PG16 cable gland located
at the bottom of the mounting bracket assembly. The cable gland can be removed and replaced
with a suitable conduit fitting if required.
Typical wire routing
The terminals used are suitable for conductors of 24 to 14 AWG (0.5 to 1.8mm Dia.). We
recommend using the 16 AWG (1.5 mm Dia.) conductors.
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-M, then electrical
power 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.
NOTE
Earthing Requirements: If the Midas-M unit's metal chassis is not connected directly to a
metal surface for earthing purposes, an additional earth wire will be required. Connect a
Midas-M
