WARNING
Risk of injury or damage to the device due to
electrical voltage and improper connection!
Failure to comply with the connection conditions
for the voltage measurement inputs can result in
damage to the device or serious injury, including
death.
Therefore, please observe the following:
· Switch off your installation before
commencing work! Secure it against being
switched on! Check to be sure it is de-
energized! Ground and short circuit! Cover or
block off adjacent live parts!
· Do not apply a DC voltage
- to the voltage measurement inputs.
- Equip the voltage measurement inputs with
a suitable, marked fuse and isolation device
(alternatively: line circuit breaker) located
nearby.
- The voltage measurement inputs are
dangerous to touch.
· Connect voltages that exceed the permissible
nominal network voltages via a voltage
transformer.
· Measured voltages and currents must
originate from the same network.
