3.9.8. ENCL
ENCL provides an electrical connection to the main enclosure. ENCL should be linked to the 0V
connection to improve electrical noise immunity.
ENCL is isolated from 0V (unless a link is fitted between 0V and ENCL).
If equipotential bonding or earthing is required then there are 2x M4 threads around the
perimeter of the display endcap. As per e.g. EN60079-14:2008 section 12.2.4 the ID5002P
must be isolated from earth or connected at one point to the equipotential bonding system.
3.9.9. CL+ / CL-
CL+ / CL- provide a current loop output for remote signalling.
CL+ is connected to the current loop supply (in to unit). CL- is connected to the current loop
return here (out of unit).
CL+ / CL- are isolated from 0V and all other connections.
3.9.10. RS485+ / RS485- / RS485G
RS485+ / RS485- / RS485G provide an RS485 interface for remote signalling and interaction
with the unit.
RS485+ / RS485- / RS485G are isolated from 0V and all other connections.
3.9.11. NO1 / COM1 / NC1 / NO2 / COM2 / NC2
These connections provide two isolated, Single Pole, Double Throw (SPDT) relay outputs for
remote signalling.
NO1 / COM1 / NC1 / NO2 / COM2 / NC2 are isolated from 0V and the SPDTs are isolated from
each other and all other connections.
