8.1 Preparation
No special measuring instruments are required for commissioning on
site except a multimeter. It is recommended to use the voltage test
module STM-02.
8.2 Voltage-Test Module STM-02
To protect your lift control unit against damage from excess voltage
while installing or repairing it, use the voltage test module STM-02
especially designed for this purpose.

!
For monitoring purposes, integrate the voltage test module in the
control unit for the time of commissioning. Remove it as soon as
commissioning is finished. You can use it for further operations.
8.2.1 Prior to the First Switch-on
According to VDE 0100 (standard from VDE (association of German
engineers) and TRA (German Safety Regulations for lifts), the control
circuit has to be earthed. For that reason, the »PE«-terminal of the lift
control unit is connected to terminal 100 of bp308 by a green/yellow
conductor.
C
AUTION
!
Make sure that the lift system does not carry any voltage!
•
Disconnect the green/yellow protective earth conductor from ter-
minal 100 of bp308. The negative potential of the control circuit
now must not have any contact with the PE potential of the control
unit at any point whatsoever in the lift system.
•
You must therefore ascertain before connecting the STM-02 device
that there really is no connection between the PE terminal of the lift
control unit and terminal 100 of bp308. Use an Ohm-meter or a cir-
cuit continuity tester.
•
After having completed these checks, you can connect the voltage
testing module STM-02 as shown in the diagram enclosed. Con-
nect conductor 1 to terminal 100 in bp308 and conductor 2 to ter-
minal 20A of the terminal strip in the control unit.
Now you can start your installation or repair work.
