supply. If necessary, use a mains filter to protect Testomat 2000®
Fe against interference voltages caused, e.g., by solenoid valves
or large motors. Never lay connecting cables parallel to power ca-
bles.
Operation
Ensure that the maximum electrical load capacity of the relay out-
puts is never exceeded.
Immediately switch off Testomat 2000®Fe and contact service
staff if malfunctioning occurs. The warranty will be void if you tam-
per with or attempt to repair Testomat 2000®Fe. Repairs must be
carried out by authorised service staff.
