INSTALLATION
!
The controller is equipped with a 3-wire power cord and
plug (internationally approved) for user's safety. Use
this power cord and plug in conjunction with a properly
grounded power socket to avoid electrical shock.
High voltage developed in the controller can cause
severe injury or death. Before servicing the unit,
disconnect the input power cable.
The controller must be installed inside a rack module,
but it must be positioned so that free air can flow
through the holes. Do not install or use the controller in
an environment exposed to atmospheric agents (rain,
snow, ice), dust, aggressive gases, or in explosive
environments or those with a high fire risk.
During operation, the
conditions must be respected:
•
temperature: from 0 °C to +45 °C
•
relative humidity: 0 - 95%
(without condensation)
To connect the controller to the pump use the specific
cable supplied with the controller.
See the section "Technical Information" for detailed
information about the above mentioned and the other
connections, and about the options installation.
