8. ELECTRICAL CONNECTION
Electrical connection
The electrical connection of the substation must be performed by a
qualified and authorised electrician in compliance with all applicable
rules and regulations.
The station should be connected to a 230 V AC power supply.
The power supply / connection must be carried out in accordance with
the applicable regulations and instructions.
The station must be wired and connected to an external main switch so
that it can be disconnected during maintenance, cleaning and repairs
or in the event of an emergency.
Do not forget
to establish potential equalization.
The VXe SLS are delivered with Danfoss ECL Comfort 310 controllers
from factory. The actuator and sensors are mounted in the station. The
controller is built into the console at the top of the station.
The station is wired and tested in the factory.
Electrical connections between the controller, pump(s), sensor and
actuator(s) are made.
Mounting of outdoor temperature sensor (ESMT)
The outdoor temperature sensor is delivered separately and must be
mounted on site according to the enclosed illustrations.
The outdoor sensor is always to be mounted on the coldest side of the
property, where it is less likely o exposed to direct sunshine (normally
the north side of the property).
The sensor must not be exposed to the morning sun, and should not be
placed above windows, doors, air vents or other heat sources, and not
under balconies and roof eaves.
Mounting height approx. 2.5 m above ground.
Temperature range: -50 to 50° C.
Electrical connections
The cables can be connected to the sensor in any order.
Connection cable: 2 x 0.4 - 1.5 mm²
Connection for ECL 310:
Connect the cable ends to ECL controller in common ground terminal
and in terminal 29.
Access to ECL base part
Access to the base part for connection of outdoor sensor or the like is
obtained by pulling the lock (pin) down with a screwdriver until a yellow
line is visible on the lock. Then, the front piece can easily be removed.
Lock by pressing the lock (pin) up.
Mounting of immersion sensor
The immersion sensor for accurate temperature measurement and
control in the cylinder is supplied separately and must be mounted
and connected to the controller on site.
Temperature range immersion sensor: 0 to 100 °C
Temperature range immersion pocket: 0 to 180 °C
2-wire cable (2 x 0.34 mm²) spliced is preassembled in the controller.
1) Mount sensor pocket (separately delivered) in top or bottom of
cylinder.
2) Lay immersion sensor and cable from substation to cylinder and
mount immersion sensor in immersion pocket.
In case the length of the sensor cable is not long enough for your
property, it is recommendable to change the whole cable. The
minimum area for the cable is 0,4 mm² and max. length is 125 m.
For electrical connections please refer to enclosed Mounting Guide
for Danfoss ECL.
