*Model part codes
To select a model in the SLA range, insert either NM or M describing the system operation and the system duration 1,2 or 3 hours. Options required should be specified using the relevant suffix e.g. "/LE" = Low electrolyte alarm, e.g. SLA/110/ 46/M3VR/LE is a 110V Maintained system supplying 1350 watts for 3 hours via its Valve Regulated, lead acid battery and has a Low electrolyte alarm facility.
