3.1 Regulations
Prior to installing the units, power must be turned off
The connections for mains and low-voltage are separated
For wiring, the requirements of safety class II must be satisfied.
One and the same sensor cannot be connected to several inputs
Sensor and power cables must not be run in the same cable duct
3.2 Heat pump controller RVS..
Planning
Air circulation around the controller must be ensured, allowing the unit to emit the
heat produced by it.
A clearance of at least 10 mm must be provided for the unit's cooling slots at the top
and bottom of the housing.
That space should not be accessible and no objects should be placed there. If the
controller is enclosed in another (insulating) casing, a clearance of up to 100 mm
must be observed around the cooling slots
The controller is designed conforming to the directives for safety class II devices
mounted in compliance with these regulations
Power to the controller may only be supplied when completely fitted. If this is not
observed, there is a risk of electric shock hazard near the terminals and through the
cooling slots
The controller must not be exposed to dripping water.
Permissible ambient temperature when mounted and when ready to
operate: 0…50 °C
Power cables must be clearly separated from low-voltage cables (sensors) observing
a distance of at least 100 mm
