Note!
If the intended storage time is longer than 3 months after reception, please refer
to section B.4.v for input on proper storage conditions.
It is important to consider the information below when planning the installation
of the failsafe actuators. Due to it being a solution with a battery, it cannot sit
without external power for an unlimited time due to self-draining. See
Table 21:
Battery lifetime below for details on expected battery lifetime. It is important to
both select an installation strategy for the actuators, and to respect the battery
lifetime estimates during the installation.
Based on this information, Eltorque has made the following input on how the
products can be handled from reception to fully commissioned.
The actuator is shipped with the battery installed in the module, but without the
battery connected to the UPS management card. When received one can choose
between installation method A or B. Installation method A can be installed in
either way 1 or 2.
A. Install the actuator with the battery mounted in the module of the installed
product. This installation method can be divided into two options:
1. Connect the battery when installing, (see Table 21, pos 4 for estimated
battery lifetime)
2. The battery is Not connected until a later stage (see Table 21, pos 3 for
estimated battery lifetime)
B. Install the actuator without the battery mounted in the module of the
installed product. The battery is removed from the product, following the
procedure in section
B.8.ii steps 1-9 and stored as described in section
B.4.v Storage on page 71. The battery needs to be installed at a later stage
when external power is available. The battery needs to be charged according
to the required specifications.
