12. Seal off open access points for cable glands using appropriate seals.
13. Close the junction box cover.
 M4: 4.0 – 5.0 Nm (2.95 – 3.70 ft lbs)
 M5: 7.5 – 9.5 Nm (5.55 – 7.00 ft lbs)
Connect the drive control to the mains
CAUTION
Destruction of the isolation system due to excessive connection voltages!
1. The G-BH1 | G-BH9 can be operated at mains voltages ≤ 500 V on the drive
control provided the permitted voltage peaks are observed.
2. Permitted voltage gradient ≤ 9 kV/μs.
3. Û
Conductor–Conductor
≤ 1500 V, Û
Conductor–Ground
≤ 1100 V.
4. Wavefront duration ts > 0,1 μs.
NOTICE
Failure to reach the pressure values due to insufficient voltages on the mo-
tor terminal board!
!
The voltages given on the rating plate (item H, [
➙
13]) apply to mains opera-
tion.

For operation of the G-BH1 | G-BH9 on the drive control, the voltages given
on the rating plate must be adhered to on the motor terminal board.
NOTICE
G-BH1 | G-BH9 with UL approval may not be operated in the USA without
testing of the drive control by a testing agency!

G-BH1 | G-BH9 must be certified by a testing agency or operated without a
drive control.
Observe when operating with drive control
▪
The G-BH1 | G-BH9 is equipped with an asynchronous motor and must be
controlled correspondingly.
▪
G-BH1 | G-BH9 with PTC resistor (option A11): When the PTC resistor is acti-
vated, the G-BH1 | G-BH9 must switch off.
▪
For G-BH1 | G-BH9 without PTC resistor, provide motor protection measures.
▪
Observe [
➙
40] revolution limits.
▪
In the case of installed sensors (e.g. PTC resistor), interfering voltages may
occur in the sensor wiring depending on the type of drive control.
▪
Observe the operating instructions of the drive control manufacturer.
Connect integrated drive control 2FC4

Connect integrated drive control 2FC4 (item 600i, [
➙
15]) according to the
drive control operating instructions [
