11.2 Mains supplies
The Supercal 531 can be supplied by battery or mains modules. They can be retrofitted at any
time.
The mains modules are provided with a jumper. The backup-battery can be activated or deacti-
vated by this jumper. When commissioning the integrator 531, the jumper is plugged-in (activated).
