THE LOCAL RELAY UNIT houses an inverter. This

converts the 230V single-phase input into a

three-phase 230V output. The inverter provides a

soft start to the motor, which extends the motor life

by minimising the start current.

For Inverter panels only

(fan types B80 / B160 & B300):

MAXIMUM length of cable between inverter

and fan is 5m (EMC class A building) or

10m (EMC class B building).

N.B. if in doubt, do not exceed 5m.

NOTES:

REMOTE SWITCH INPUTS

should be connected by 6A mains

Max length is 100m.

Low voltage switching inputs to be

normally open (closed circuit to

enable).

Connect to B0 & B1 for remote ON

(ie BMS time control).

Connect to B0 & B2 for remote

OFF (ie door interlock. remote

frost etc).

*The power supply is non-isolated,

therefore all wiring to the control must be

mains rated.

REMOTE SENSOR(s) may be

placed at a max distance of 100m

from the control unit, using

screened 6A mains* cable.

Wiring should be kept separate

from mains wiring to minimise

noise pick up. Set within Engineers

functions for remote sensor.

*The power supply is non-isolated,

therefore all wiring to the control must be
