Storage
If a DECS-250 will not be placed in service right away, store it in the original shipping carton in a
moisture- and dust-free environment. The temperature of the storage environment must be within the
range of –40 to 85
°
C (–40 to 185
°
F).
Electrolytic Capacitor Considerations
The DECS-250 contains long-life aluminum electrolytic capacitors. For a DECS-250 kept in storage as a
spare, the life of these capacitors can be maximized by energizing the device for 30 minutes once per
year. Refer to the energizing procedures provided in
Maintenance
.
When energizing the DECS-250 from a low impedance source (such as a wall outlet), use of an Inrush
Current Reduction Module (ICRM) is recommended to prevent damage to the DECS-250. For a detailed
description of the Inrush Current Reduction Module, refer to Basler publication 9387900990. ICRM
connections are illustrated in
Typical Connections
.
