EMH metering EM4TII Gebrauchsanleitung Seite 27

DANGER!
Contact of parts under voltage is extremely dangerous!
When installing or changing the meter, the conductor to which the
meter is connected must be de-energized.
• Remove the relevant back-up fuses, for two-sided supply on the
mains side as well as on the generation side.
• Store the back-up fuses in such a way that other people cannot
refit them unnoticed.
• If you use selective circuit breakers for disconnection from the
mains, secure them against being switched on again unnoticed.
• Only use the dedicated screw terminals for installation and
connection of the meter.
DANGER!
Risk of danger to life due to electric arc and electric shock!
The inputs and outputs including the external power supply inputs are
not secured internally.
• Secure the inputs/external power supply inputs with back-up fuses
of ≤ 0,5 A according to valid technical directives.
• Secure the outputs in compliance with the current value specified
on the nameplate of the meter according to valid technical
directives.
NOTICE!
Damage of the terminals due to excessive torque!
The appropriate torque depends on the type of the connection line and
on the maximum current.
• Tighten the terminals with the required torque according to
IEC 60999-1.
