4.3 Installation
All procedures in this manual must be strictly adhered to.
Any deviation from these could cause irreversible damages
to the Hydran M2-X and/or the transformer being monitored,
and could lead to property damage, personal injury and/or
death. Installation and maintenance of the Hydran M2-X
must be carried out by qualified personnel only.
The installation and commissioning of the Hydran M2-X are divided in several
steps. This Section provides a detailed description of each step; Appendix B provides
a checklist for the entire installation procedure.
It is strongly recommended to verify the operation of all
Hydran M2-X’s before installation in the field. The verification
also allows the user to become familiar with the Hydran M2-
X; see Section 4.2.
Note: It is strongly recommended that the parameters of each Hydran M2-X
(identification number, power station identification number, communication
speed, operation mode of relays, etc.) be set before field installation.

or rigid steel conduit toward a supervisory control and data acquisition
(SCADA) system.
