Electrical connection
Risk of fatal injury due to electric shock.
Î
Do not remove any covers to perform
adjustment work on live parts.
Î
Before performing any work on the de
-
vice and before opening the device, dis-
connect the supply voltage and protect it
against unintentional reconnection.
Î
Only use power interruption devices that
are protected against unintentional re
-
connection of the power supply.
Î
The electric actuators are protected
against spray water (IP 54). Avoid jets of
water.
Upon installation of the electric cables, you
are required to observe the regulations con-
cerning power installations according to
DIN VDE 0100 as well as the regulations of
your local power supplier.
Use a suitable power supply which guaran-
tees that no dangerous voltages reach the
device in normal operation or in the event of
a fault in the system or any other system
parts.
Only connect the actuator to the power sup
-
ply after switching off the supply voltage.
Make sure the supply voltage cannot be
switched on again unintentionally.

5.6
Start-up
Î
Do not start up the regulator until all
parts have been mounted.
Î
Make sure that the restriction (8.5 or 8.6)
is open while filling the plant. To do so,
use the electric actuator (10) to open it.
An electric actuator with "Actuator stem
extends" fail-safe action must be re-
moved first. Turn the set point screw (8.3)
or set point adjuster (8.2) for the flow
control clockwise (
) as far as it will go
(see Fig. 3).
Î
Open the shut-off valves slowly over a
time period of several minutes starting
from the upstream pressure side. After-
wards, open all the valves on the con-
sumer side (downstream of the regula-
tor).
− The TROVIS 57xx and Type 58xx Electric
Actuators are started up and operated as
described in the actuator documentation
− The Type 2430 Control Thermostat is start-
ed up and operated as described in the
associated documentation (Referenced
documentation
).
