Bitzer CM-RC-01 Instructions De Service page 13

If no additional extension kits are mounted:
• Proceed with the other electrical connections on the
CM-RC-01 (see chapter Further electrical connec-
tions on the CM-RC-01, page 10).
• Mount the cable holders, lay the cables and close
the cable ties (see chapter Mounting the cable hold-
ers and laying the cables, page 10).
• Screw the protective earth conductor onto the ter-
minal box cover and attach the cover to the module
housing (see chapter Closing the module housing,
page 10).
KW-233-1
4.2 Mounting the "Pressure transmitter" extension kit
NOTICE
!
!
The two pressure transmitters must not be inter-
changed. They differ by the component number
engraved in the component:
High pressure transmitter: 2CP5-71-47.
Low pressure transmitter: 2CP5-71-49.
Information
Alternative mounting position for discharge gas
temperatures exceeding 135°C:
Connect the pressure transmitters to the dis-
charge gas line, as close as possible to the
valves using one refrigerant hose each. Length
of the refrigerant hose: at least 200 mm to avoid
overheating of the transmitter.
• Remove the HP and LP sealing plugs and
clean the threaded bore.
• Screw in the enclosed screwed nipples (low
pressure transmitter) or T-piece (high pres-
sure transmitter) with Schrader valve.
• Then screw the high pressure transmitter
(2CP5-71-47) into place at the HP position
and the low pressure transmitter
(2CP5-71-49) at the LP position (tightening
torque 35-40 Nm). Do not insert a blanking
plate between screwed nipple and pressure
transmitter, since this will prevent the
Schrader valve from opening!
• Snap the connector into place and guide the
cable to the compressor module.
• Connect the cable of the high pressure trans-
mitter to terminal strip CN12, terminals 1, 2, 3
(designation "pdis") on the compressor mod-
ule.
• Connect the cable of the low pressure trans-
mitter to terminal strip CN12, terminals 4, 5, 6
(designation "psuc") on the compressor mod-
ule.
• Pay attention to the correct cable connec-
tions!
