DECS-150 Maintenance
26 • Maintenance
These servicing instructions are for use by qualified personnel only. To
reduce the risk of electric shock, do not perform any servicing other
than that specified in the operating instructions unless you are
qualified to do so.
Before performing any maintenance procedures, remove the DECS-
150 from service. Refer to the appropriate site schematics to ensure
that all steps have been taken to properly and completely de-energize
the DECS-150.
Preventive Maintenance
Connections
Periodically check the connections of the DECS-150 to ensure they are clean and tight and remove any
accumulation of dust.
Electrolytic Capacitors
The DECS-150 contains long-life aluminum electrolytic capacitors. For a DECS-150 kept in storage as a
spare, the life of these capacitors can be maximized by energizing the device for 30 minutes once per
year.
To energize the device, apply operating power within one of the following ranges:
• 100 to 139 Vac, or 125 Vdc
• 190 to 277 Vac, or 250 Vdc
When energizing the DECS-150 from a low impedance source (such
as a wall outlet), use of an Inrush Current Reduction Module (ICRM-7)
is recommended to prevent damage to the DECS-150. For a detailed
description of the Inrush Current Reduction Module, refer to Basler
publication 9387900990. ICRM-7 connections are illustrated in Typical
Connections.
Cleaning the Front Panel
Only a soft cloth and water-based solutions should be used to clean the front panel. Do not use solvents.
Storage
If the DECS-150 is not installed immediately, store it in the original shipping package in a moisture- and
dust-free environment.
