EE07 probes connected to EE220 with extension cables

The probes can be also connected to the EE220 housing with extension cables, see chapter
"14. Accessories".
The EE07 probe may be mounted pointing upwards or downwards. The probe can be fixed onto
a wall with the wall mounting clip HA010211.
For outdoor use each EE07 probe shall be used with a radiation shield, order number HA010502.
In very humid, condensing environment the probe should be installed horizontally. Probes point-
ing downwards shall be protected by the drip water protection, order number HA010503.
4.2.3

EE07 duct mounted

The duct mounting kit HA010209 includes an extension (200 mm /
mounting flange. It facilitates the EE07 mounting into ducts with thick walls or thermal isolation.

Probe Protection During Cleaning and Sterilizing
operations
Periodical cleaning and sterilizing operations are common in pharma and food industries, as well
as in incubators or hatchers. Cleaning and sterilizing agents may affect the sensors and lead to
drift and corrosion. It is highly recommended to either protect or remove the EE07 probes during
cleaning and sterilizing.
5.2.1

Probe protection

Place the plastic protection cap HA010783 on the probe before starting cleaning or sterilizing and
remove it after that. This is not necessary for the EE-07MT metal temperature probe.
5.2.2

Probe removal

When removing the probes before starting cleaning or sterilizing, use the M12 protection caps
for the EE220 probe connectors or cable connector (HA010781) which remain on site. The probe
connector can be also protected with the cap HA010782.

EMC recommendations for wiring
The requirements of EMC standards as specifies in the technical data are only fulfilled with the
EE07 probes connected either directly or with E+E original extension cables to EE220.
• E220 with metal enclosure must be grounded either at the designated points on the inside, or
outside at the mounting plate.
The EE07 probe may not be grounded; it must be electrically isolated from the GND.
• Locate the EE220, the probe cable and the output cables as far as possible from sources of
electromagnetic disturbances.
• For the analogue outputs use either shielded or twisted cable pairs. The shield shall be ground-
ed at one end only, preferably at the controller side.
• Cable loops may impact on the EMC behavior of EE220. Keep all cables as short as possi-
ble. Unused wires shall be grounded at both ends. Run all cables as close as possible to the
ground potential, for instance close to the walls or steel structure elements.
