2.5.1 TAG FOR VOLTAGE AND CT CONNECTIONS

Product to be protected by an external fuse, model KTK-1 by

Bussmann, or similar, rated 600V, 1A. It should be provided with a

MCCB or equivalent device to switch off the system from the power

supply circuit. The power supply and voltage measuring circuit is

connected with cable minimum cross section of 1 mm

(AWG 17). The

current transformer secondary side connection line should have a

minimum cross section of 2 mm

(AWG 14 Cu) and with a minimum

temperature rating of 60 ºC.
