Bitzer CM-RC-01 Instructions De Montage page 23

▶ Shorten the cables as needed, pass them through
the cable glands on the compressor module into the
module housing and connect them to the CN6 ter-
minal strip.
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 21).
• Mount the cable holders, lay the cables and close
the cable ties (see chapter Mounting the cable hold-
ers and laying the cables, page 21).
• 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 21).

4.2 Mounting the "Pressure transmitter" extension
kit
NOTICE
!
!
The two pressure transmitters must not be inter-
changed. They differ by the inscription "HP" or
"LP" on the component:
High pressure transmitter: HP.
Low pressure transmitter: LP.
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 pres-
sure transmitter) or T-piece (high pressure transmit-
ter) with Schrader valve.
▶ Then screw the high pressure transmitter (HP) into
place at the HP position and the low pressure trans-
mitter (LP) 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 transmitter
to terminal strip CN12, terminals 1, 2, 3 (designation
"pdis") on the compressor module.
