2. Safety instructions
2.1 General safety instructions
Part of the device documentation in addition to this manual are the enclosed "Safety instructions for
Bender products".
2.2 Working on electrical installations
If the device is being used in a location outside the Federal Republic of Germany, the applicable local
standards and regulations must be complied with. The European standard EN 50110 can be used as
a guide.
2.3 Intended use

Monitoring and analysis of data centres
3.4 Function
CP9…-I are integrated into the existing EDP structure like PCs. After connection to the network and
compatible Bender products, all system devices can be accessed from any PC using a web browser.
In this way, all important system information is directly available. Verified web browsers: Microsoft
IE, Mozilla Firefox, Google Chrome.
3.5 BMS interface
The majority of Bender devices communicate via the internal BMS bus. CP9…-I can be operated as a
master or as a slave.
3.6 Address configuration and termination
To ensure proper functioning of the CP9…-I, correct address assignment and termination is of ut-
most importance.
CP9…-I is to be operated as a master if:
- Parameters are queried or changed
- Certain control commands are issued
Note that not all BMS masters can surrender their master function!
Multiple assignment of addresses
The factory setting for the system name on all Bender BCOM devices is "SYSTEM".
If several systems with the same system name are integrated into the same
network, addresses are assigned twice. This leads to transmission errors. Always
enter a unique BCOM system name during initial configuration.

CP9xx-I_D00418_02_M_XXEN/04.2021
3.7 Functional description
3.7.1 Interfaces
CP9…-I communicate with the devices and systems assigned via various interfaces:
Internal BMS bus (RS-485) for Bender systems such as EDS46x/49x, RCMS46x/49x and MEDICS.
CP9…-I can be operated as a master or as a slave. When operated as a master, requests are
answered more quickly. The devices can only be operated on the internal BMS bus.
BCOM (Ethernet) for new and future Bender systems, such as ISOMETER® iso685-D.
Modbus RTU (RS-485) CP9…-I when operated as a master for Bender devices PEM… with
restricted functionality (full functionality of PEM…5only via Modbus TCP).
Modbus TCP (Ethernet) for Bender devices PEM…5

3.7.2 Process image
The CP9…-I prepares and saves a process image from the communicationwiththe devices assigned.
This process image contains alarms, status information and measured values from the devices as-
signed.
The CP9…-I combines the information from the different interfaces and makes it available for:
Display and configuration via the system overview on the display or web interface
Display and operation via the visualisation on the display or web interface
Transmission to external systems via Modbus TCP or SNMP
The CP9…-I provides a common user interface for the devices assigned via different interfaces. On
this user interface, each device is given an individual address by which it can be identified. BMS,
BCOM and Modbus RTU devices receive the appropriate address for their interface. A virtual address
is assigned to Modbus TCP devices so that they can be addressed correctly in the system.

CP9xx-I_D00418_02_M_XXEN/04.2021
4. Mounting, connection and commissioning
4.1 Mounting of the CP9…-I device
The COMTRAXX® CP9…-I devices are installed either in the supplied and professionally pre-assembled flush-
mounting enclosures or with the optionally available control cabinet door mounting (CP907-I only).
4.1.1 Dimension diagram
Only qualified personnel are permitted to carry out the work necessary to in-
stall, commission and run a device or system.
Functional ground
The device must be earthed. Without connection of the functional earth, the device
function is not guaranteed.
Electrostatic sensitive devices
Observe precautions for handling electrostatic sensitive devices.
Damage to components
Do not remove the device from the enclosure during ongoing operation. First, dis-
connect the device from the supply voltage and from the network (Ethernet).
Damage to the device due to incorrect connector plug
A connector plug of another device may have a different polarity.
Make sure to use the supplied connector plug!
Safe separation
The supply shall be properly separated from hazardous voltages and meet the limits
of UL/CSA 61010-1, Clause 6.3.

Removing the CP915 front plate
The front plate is removed from the enclosures of the CP915-I devices using a suction lifter. For this purpose,
the suction lifter must be placed on the points marked below one after the other and the front plate must be
removed until it clicks into place for the first time. If the front plate is detached on both sides, the plate can be
lifted off the enclosure.
Damage to the display front
Placing the suction lifter in the middle and pulling only at this point may damage the
front plate.
Always place the suction lifter on the edges of the display.
