◗ The circuit-breaker cabinet must be located as close to the battery as possible.

◗ The cabinet is fixed to a vertical wall by means of 4 screws of diameter 8 using the fastening lugs placed in the vertical or

horizontal position.

◗ The cabinet door is closed by two lock knobs with a key (405 type) on one of the knobs.

◗ The cabinet version with insulation controller has the same characteristics as the standard version (except for

dimensions), with the insulation controller being located in the upper part of the cabinet door.

◗ Cables are fed through the bottom of the cabinet via a 315 x 90 mm opening for a 400 mm wide cabinet.

◗ The characteristics of the cabinets indicated in the tables below are valid for a linear load charge with power factor of 0.8.

◗ The recommended cable cross-sections are applicable to U1000R02V type copper conductors. They are calculated in

relation to permissible temperature rises and take into account a maximum line voltage drop of 1% for a maximum cable

length of 25 m. For greater cable lengths, cross-sections will be chosen to keep the voltage drop within 1%.

◗ The cross-section of the power cables is given in the tables in the section entitled "characteristics of cabinet".

◗ Recommended cross-section of auxiliary conductors: 1 mm2 (terminal acceptance capacity: 2.5 mm2).

◗ Make sure that the auxiliary conductors and power cables do not follow the same path.

◗ Power cables and auxiliary conductors are not supplied.

Important: leave the QF1 circuit-breaker in "off" position until the Galaxy 3000 unit has been commissioned.
