Do not exceed the recommended torque as this may permanent-
ly damage the instrument.
6. Wipe excess oil with a clean cloth.
Re-install the external sampling port cover and secure
with the 5 mm Allen key.
The thermal pump must be turned off when the product
is empty (this can be done in the web interface (see docu-
ment: "eDOC web interface" Manual Instruction) or locally
through the 3 buttons. See chapter "De-Commissioning
(without web interface)" on page 12.
COMEM recommends to power on the eDOC when it is
filled of oil.
To prevent accidents, the eDOC is delivered with the
thermal pump turned off. When the installation is com-
plete and the product is in contact with oil, make sure the
thermal pump is enabled, in the web interface (see docu-
ment: "eDOC web interface" Manual Instruction) or locally
through the 3 buttons. See chapter "De-Commissioning
(without web interface)" on page 11.
Operating the heater in air will result in failure of the thermal
pump.

NOTE
Removing the cover
WARNING
Disconnect power from the distribution panel prior to removing
the cover.
1. Unscrew the retaining screws from the enclosure
cover with the 5 mm Allen key.
2. Remove the enclosure cover.
3. Discard the used o-ring, if necessary.
Connections
WARNING
Make sure to comply with the national electrical standards.
Disconnect power at the electrical distribution panel prior to
performing any adjustment (connections) on the product. The
eDOC is equipped with six ports for cabling. Make sure the
power cables (line voltage) and all other cables are routed sep-
arately in a dedicated cable port through a proper cable gland
(i.e., there must never be more than one multi-strand cable
through any of the cable glands). Putting two cables through a
cable gland invalidates the IP67 protection, allows water ingress
and creates an electrical hazard.
Prior to establishing connections inside the eDOC:
1. Make sure to ground the eDOC, either by means
of the three-wire cable on the internal ground wire of
the power cable or with a separate cable to the
external ground lug.
2. Install on the product the required watertight cabling.
