Keystone ePi-2 quarter-turn electric actuator
InstallatIon and MaIntenance InstructIons
iMportant
In case the screws of the cover must be replaced,
SS Class A4 grade 80 screw must be used with
minimum yield strength 600 N/mm
Warning
Do not electrically operate the EPI-2 when
the electrical enclosures are removed. Do not
open the actuator covers when an explosive
atmosphere may be present. Ignoring the above
precautions could cause personal injury.
iMportant
Each time the covers are opened or removed the
condition of the seals must be checked.
In case the seals are replaced, original spares
must be supplied by Pentair.
iMportant
EPI-2 electric actuators must be installed
and maintained according to the applicable
rules regarding the electrical installation in
hazardous areas (other than mines) classified as
zone 21 and/or 22 (dust) according to EN 60079-10
(hazardous area classification).
Example: installation and maintenance according
to EN 50281-1-2.
special attention is requested to the following:
• Before the assembly the joint surfaces must
be greased with silicone oil or equivalent
• Cable glands must have minimum protection
degree IP66/68 (EN 60529)
• Periodically verify the quantity of dust
deposited on the enclosure and clean it if
more than 5 mm using a damp cloth to avoid
static electricity
5. luBrication
5.1 LubriCation inspeCtion
the actuator is grease lubricated for life,
therefore under normal working conditions no
grease needs to be replaced or added.
in case of maintenance the following grease is
recommended:
• AEROSHELL GREASE 7 or equivalent,
for ambient temperature -40°c to +70°c
(-40°f to +158°f).

confiGuration
Before connecting power to the actuator, check
2
that the voltages are correct and according to
the indications on the nameplate. Wrong power
supply could cause permanent damage to the
electrical components.
the configuration of the ePi-2 actuator can be
carried out through the control panel inside
the actuator control system. to access the
panel, remove the actuator cover and when the
configuration is complete replace the cover,
following the procedures indicated below.
iMportant
When optional local control panel OM3 is installed
and the actuator setting is done by means of
the pushbuttons on the logic board, the remote
controls do not have to be energized.
6.1 reMoVaL of the ControL unit CoVer
using a 5 mm allen key, loosen the four screws
and remove the cover.
iMportant
When setting the actuator parameters do not
operate the actuator neither remotely nor locally.
Warning
Pay attention not to damage the joint surfaces of
the cover.
iMportant
In case the screws of the cover must be replaced,
SS Class A4 grade 80 screw must be used with
minimum yield strength 600 N/mm
once the configuration is completed,
reassemble the actuator cover.
