6. Installation
This part is necessary for the designer willing to use the Airmaster S1. It shows how an
S1 can be integrated into an electrical circuit. Chapter 8 “Putting into operation” gives
some directions that should be known in production. We strongly advise to use these
assembly instructions.
6.1 Cable connector types
The cable connector must match with the connectors populated on the Airmaster S1.
Please refer to appendix 2 for more information.
6.2 Power supply and fusing
Power supply and fusing is an important part of the installation. An AC voltage is
required. The maximum variation on the 24Vac is +-20%.
Only for use in Class 2 Circuits
The input voltage ratings for UL are:
Class 2 or LV/C, 24 V ac, 50/60 Hz
“The input circuitry of these devices have to be supplied from:
a) A Class 2 transformer in accordance with UL1585, or
b) An isolating device such that the maximum open circuit voltage
potential available to the circuit is not more than 28.8 Vac and the
current is limited to a value not exceeding 8 amperes measured
after 1 minute of operation, or
c) A suitable isolating source with a maximum open circuit voltage
potential of not more than 28.8 Vac in conjunction with a fuse in
accordance with UL248. The fuse shall be rated max. 1,6 A and be
installed in the input circuitry of the device in order to limit the
available current.”
