The cable must be suitable for the working temperature as specified in the “safety instructions” delivered with the first supply of the products.

Power supply: section of coil connection wires = 2,5 mm

Grounding: section of internal ground wire = 2,5 mm

section of external ground wire = 4 mm

Multicertification Group I and Group II

cULus certification:

• Suitable for use in Class I Division 1, Gas Groups C

• Armored Marine Shipboard Cable which meets UL 1309

• Tinned Stranded Copper Conductors

• Bronze braided armor

• Overall impervious sheath over the armor

In case of asymmetric flow the operating limits

must be reduced.
