Make Sure Power is disconnected prior to attempting to check or replace fuses.
As there are live terminals connected through to the end of the fuse so if you
touch the fuse it could be Live!
Please check rating against labels of each fuse.

Connections to the Main Lift Control Panel must be carried out carefully to
ensure that the correct function of the signals is produced.
The control box input signals are 12V DC 100mA they require a dry / volt free
relay contact normally open and energised when the Car and Landing doors are
closed.
In addition, a connection directly to the normally closed (when not in over speed
condition) over speed governor switch is required.
The operation of these switches is essential to enable the UMD-SRB01 to operate
safely, i.e. If a cable is broken or the lift over speeds the UMD-SB01 will be FAIL
SAFE. i.e. any problems, the brakes will be deployed.
The connection from the Main Lift Panel such as Alert signal and emergency
stop must be 230Volts maximum and must not exceed 5amps. The control box
provides dry / volt free relay contacts for your signals. This is done by connecting
via the 32 way Multipole Plug & Socket.
On the next page there is a list of all the connections to the multipole plug and
their functions.
Please also see electrical drawings supplied with this manual for further
