Maintenance
BE1-87T relays require no preventative maintenance other than a periodic operational check. If the relay
fails to function properly, contact Technical Sales Support at Basler Electric to coordinate repairs.
Storage
This device contains long-life electrolytic capacitors. For devices that are not in service (spares in
storage), the life of these capacitors can be maximized by energizing the device for 30 minutes once per
year.
