Safety information and protective measures
l
When performing service work and tests, adhere to:
- the product-specific safety information in the document,
- the safety information in RAO-000.012.... in the Register of
the POLYMOBIL 10 binder,
- as well as the general safety information contained in
part 2 of the ARTD.
l
Tests and adjustments that must be performed with radiation
ON, are identified by the radiation warning symbol y .
Radiation protection must be worn during these types of
adiustments.

When working with the system open, there is danger of
! Electric shock !
l
The capacitor bank can still be charged.
Do not attempt to work on the system while this condition exists.
l
After switching off the system, approximately 350 VDC may still
be present in the system; even after disconnecting the line
voltage plug. Within 10 minutes this voltage will drop to
approximately 10 V.
l
Always measure the actual voltage present with the DVM at test
points -VCC and +VCC on the D960 inverter board or (more
accessible) on the D970 capacitor board at the + connection
point of capacitor C3 and on the right side of fuse F3 (refer to
Fig. 1).
. LED’sVl
. . . VI0 on D 970 go out at a significantly higher voltage
level and therefore they are not reliable safety indicators.
l
If a fuse on the D 970 has responded, high voltage may still be
present at the affected capacitor even after a prolonged period
of time.
l
The capacitor discharging circuit utilizes the D 925 board and
relays CS and LS. If jumpers X3 or X9 on D 925 or D 950 are not
inserted or there is a defect in the circuit, the C-bank will not
discharge.
This can cause life-threatening voltage to be present in the
system even after a prolonged period of time.

Equivalent leakage current measurement
l
Perform the equivalent leakage current measurement in accordance with

“Safety technical information for installation and start-up”.
Initial measurement
When measuring the equivalent leakage current, an initial measurement as well as repeat
measurements are taken. The purpose of these repeat measurements is to detect deviations from the “initial” measurement and thus to recognize changes in the safety structure
of the system as early as possible.
The initial value measured may not exceed the maximum value of 2
Conform to the measurement setup shown in Fig. 2.
During the measurement, POLYMOBIL 10 must be switched on. Therefore, when using
the BENDER Safety tester, it must be set to manual measurement.
The “initial” value should be entered in the test protocol at the end of these start-up
instructions.

Repeat measurements
After performing any necessary repair work and after maintenance work in general,
measure the equivalent leakage current again.
The value measured must not exceed the maximum acceptable limit value of 2 mA.
In addition, this value may not exceed the initial value by more than 50%.
The results of the measurement must be documented.
