DR Graphic recorder - Installation Instruction
Mother Board
DR Graphic Recorder
This Installation Instruction sheet is intended as a guide for replacing or installing hardware and for setting up
functionality in the recorder. Refer to the User manual for detailed operational requirements.
The DR Graphic recorders are designed for ease of assembly with minimal disturbance to the rest of the unit. If unsure,
please return the unit to your supplier for repair or upgrade.
Opening the recorder and removing the internal chassis of the recorder should only be performed under the following
circumstances:
When an item of hardware requires individual replacement.
When an item of hardware is to be retrospectively fitted.
In all other instances it is recommended that the complete unit be returned to an authorized agent or service centre. For
Agency Approved recorders the product needs to be upgraded or repaired by an Authorized Repair facility.
WARNING
HAZARDOUS VOLTAGES
Disconnect all the power, CJCs and IO cabling to the recorder before removing the IO cards chassis or power supply
chassis and attempting any maintenance procedures.
SAFETY TESTS
Upon completion of service procedures detailed in this instruction verify the installation per the installation section of the
product manual.
Failure to comply with these instructions could result in death or serious injury
CAUTION
OBSERVE ANTI-STATIC PRECAUTIONS
Refer to BS EN61340-5-1: 2001. Basic specification. Protection of electrostatic sensitive devices. Full anti-static
precautions MUST be observed when in contact with the electronics of your recorder.
SAVE DATA, SETUPS AND LAYOUTS
Removal of PCBs and battery back-up will result in the loss of all non-volatile data. Ensure all data and set-ups are
saved.

Before attempting to repair or upgrade a recorder, it is advisable to clear sufficient work space so components such as
the front panel can be rested on the work surface without getting scratched or damaged.
If adding a new piece of hardware to your recorder please be aware that if you are running Trend Manager PC software
that the “Hardware Wizard” will require updating to accommodate the hardware changes.
Panel Mounting
Mother Board can be removed, replaced or added to the recorder without removing it from its mounting panel. If you
require the recorder to be removed from the panel, loosen the mounting bracket screws and remove the recorder.
Removing the IO Card Chassis front panel
Removal of the IO Card Chassis front panel is necessary for replacement or fitting any of the PC cards. To remove the
IO Card Chassis front panel use the following procedure.
1. Open the door (Bezel side) of the unit by unlocking the latch.
2. There are 7x No.4/40 screws shown in red circle and 2x captive screws shown in green circle in Figure 1. Remove all
the 4/40 screws and loosen the captive screws.

9. Slide the new backplane card back to its vertical position and fit the backplane card 48 pin IO connector firmly into
the 48 pin processor board IO connector. Take care to align the backplane card into the card guide slots in the
chassis.
10. Make sure that jumpers are connected for slot B as per the following table.
Slot B
