7.3 Installation conditions

The control electronics VT-VPCD is designed for installation in a 19" rack or an
open card holder. Suitable card holders are listed in the following Chapter 7.4

"Recommended accessories".

▶ Provide an operating voltage of 24 VDC.
▶ Adhere to the ambient temperature range permitted according to the data sheet.
7.4 Recommended accessories
For connecting the control electronics VT-VPCD we recommend the use of the
following accessories, which are not included in the scope of supply, but which you
can order separately from Bosch Rexroth:

Installing the VT-VPCD

Please observe the following notes when installing the VT-VPCD control electronics:
For the installation, observe the notes given in the data sheet on applied standards
and operating conditions.
Use low-capacitance cables.
Install cable connections without intermediate terminals whenever possible.
Install sensor cables separately.
The presence of electromagnetic sources of interference (e.g. frequency converter)
in the direct vicinity of the control electronics is not permitted.
The distance to aerial lines, radio sources and radar equipment must be at least
1 m.
Do not install solenoid and signal cables near power cables.
Use shielded cables (EMC-compliant) as valve cables.
Execute the installation so that when the differential inputs are used both inputs
are activated or deactivated simultaneously.
Use relays with gold-plated contacts for switching command values (small voltages,
small currents).
Do not use adhesives, sealants or insulating agents that contain silicone.
The system ground is an essential integral part of EMC protection of the control
electronics. Here, interference, which is transported to the control electronics via
data and voltage supply cables, is dissipated. This function can only be ensured, if the
