Installation location
The UMG507 is intended for permanent in-
stallation in low and medium-voltage switch-
gear. It can be installed in any position.
Protective conductor
A protective conductor according to the valid
safety regulations must be connected at the
screw provided on the rear of the device
before the remaining connections with the
device can be made.
Supply voltage
An operating voltage is required to run the
UMG507. The type and strength of the operat-
ing voltage required for the UMG507 is noted
on the rating plate.
230V Standard version
120V Special version
63V Special version
Higher voltages between the terminals 31/32
and earth (PE) can severely damage the
UMG507. In order to prevent an overvoltage
the operating voltage should be earthed.
The operating voltage is connected at ter-
minals 31 and 32. A maximum voltage of
300VAC may occur between the terminals 31
and 32 (operating voltage) and earth (PE).
Attention!
- The wiring cables for the operating voltage
must be suitable for nominal voltages up to
300VAC to earth.
- The operating voltage must be fused. The
fuse must lie within the range from
2A to 10A.
- The building installation must include a
switch or circuit-breaker for the operating
voltage.
- The
switch must be installed close to the
device and be easy for the user to reach.
- The switch must be
labelled as a discon-
necting device for this device.
- Before applying the operating voltage ensure
that the voltage and frequency comply to the
values given on the
rating plate!
- The device may only be run with an
earthed
housing!
- Conductors with
soldered individual wires
are
not suitable for connections at screw-
type terminals
!
-The pluggable screw terminals may only be
plugged in when no voltage is applied.
- Only pluggable screw terminals with the
same number of poles
and the same type
(with/without threaded connection) may be
connected with each other.
Voltages which lie above the permis-
sible voltage range can severely dam-
age the device.
