The RESM-5 monitoring unit can be used as an
alternative to the RESM-4.
The steps necessary to convert from RESM-4 to

latest version of the monitoring unit documentation,
which is always binding.
The electrical connections of the RESM-4 and RESM-5
monitoring units are NOT compatible (see wiring
diagrams).
