KBR multilog 3 Operating Manual page 19

DANGER!
CAUTION!
2) Current clamp connection (Amphenol plug 7-pole)
3) The multilog 3 is equipped with an internal extremely robust wide-range power supply.
The power supply is designed for the high immunity of 300V CAT IV and complies with the pro-
tection class IP65.
The PQ box can be supplied with energy directly at the measuring point via this adapter and
does not require a separate socket.
The following voltage ranges for the mains supply are possible: 88 V ... 500 V AC or
100V ... 300V DC
High-voltage fuses are installed in both measuring lines. These can be exchanged by the user.
CAUTION!
DANGER!
Danger to life due to electric shock!
The maximum voltage of the reference earth (green) must not exceed
the requirement of 600V against earth
 Ensure that the device is not operated above the rated data
Damage to measurement voltage with overvoltage
 Connect device to maximum DC voltage of 565V AC / 800V DC L-N.
 Connect device to maximum AC voltage of 980V AC / 1380V DC L-L.
Damage to power supply due to under- or overvoltage
 Only power the device between 88V and 500V AC.
 Only supply power between 100 and 300 V DC.
 Do not supply the device directly from strongly disturbed voltages.
(eg. at the frequency inverter output / Caution high clock frequencies
can destroy the internal power supply)
Danger to life due to electric shock!
Only fuse 6.3mm x 32mm, 3 A F, with a breaking capacity of
50kA/600V may be used in the fuse carrier. Only fuses with the
identical data may be used.
 Make sure that the fuses used comply with the specifications.
