f) using voltmeter, measure output voltage on connectors’ contacts (for load
connection); measured values shall be 24 V DC. If measured voltage is different from
the rated value, the Product is not ready for operation. Contact the Manufacturer;
g)transfer piano type switch to “OFF”position and connect the load;
h)switch the Product on and check operation of load.
2.2.4 To switch the Product off:
a) switch off the load (only if a load may be switched off by a switch located on
the load casing; in another case, a load switches off once the Product power is turned
off);
