INSTALLATION
1. Check that the number, size and the speed of the fans can be safely controlled by this
controller.
2. Install in a dry sheltered position. Leave an air space of not less than 150mm around the
controller to allow cooling air to flow freely. Do not install in close proximity to other heat
sources. The maximum ambient temperature for the controller must not exceed 40°C.
3. Remove front cover of the controller by removing cover fixing screws. This provides access
to the terminals and mounting holes that are under the lid. The gasket (REB 8, REB 10, REB
12 and REB 16 only) prevents the ingress of moisture and dust. If more than one fan needs
to be controlled, the connections can be made in parallel to a junction box (by others).
4. Two types of fan motor are currently used. One has terminal designations L and N and
either a pre-wired capacitor or a separate capacitor where particular attention must be paid
to the connections to the capacitor (wiring Diagrams 6 and 8). The second type has
terminals marked U,V,W,X,Y,Z and a capacitor fitted to the motor. In each case the
connections must be as shown in the wiring diagram.
5. Should the current rating of the fuse in the controller exceed that of the wiring of the fan(s)
circuit(s), each fan should be protected independently. If individual protection for each fan
is being employed, then this should be situated in each common line (the supply from
controller terminal U2) only.
6. If the controller is intended to control multiple fans, then those fans must be of the same
model/size.
7. All cable entries provided should be used. Any left unused should be blanked and left in a
safe condition.
WIRING THE MOTOR
8. Use table 2 on page 4 of this booklet to establish which wiring diagram should be followed
when connecting popular S&P fan models to the correct controller. For fans not listed, refer
to diagram 8. IF IN DOUBT, ASK! Note that the table is for dedicated fan control only (I.e.
one fan per controller). Multiple fan control is possible; however table 2 will no longer apply
and notes #1, #5 and #6 above must be followed.
9. Where fan is 2-wire control (I.e. only live and neutral at fan terminal box), then omit the
connection from the controller AUX terminal and connect links as per the diagram on the
fan. Where the fan under control incorporates thermal protectors (TP terminals) then they
must be connected, please refer to points 15 and 16 in this booklet.
10. Check that the unit mountings and electrical connections are secure and in accordance with
the wiring diagrams on pages 5 and 6 of this booklet. Please note that the 6-way terminal
blocks on many S&P commercial/industrial fans are marked with 2 sets of designations and
that particular attention to the markings should be made:-
Terminal U is additionally marked U1
Terminal V is additionally marked V1
Terminal W is additionally marked W1
Terminal X is additionally marked U2
Terminal Y is additionally marked V2
Terminal Z is additionally marked W2
