3.3 Special attention on 3-pole use (24 V or 42 V)
Using Slam® Trans -unit with 3-pole socket outlets (with bonding) is a simple way to solve the
problems with static electricity of relating equipment. By connecting the bonding cable
(supplied with transformer) to the local equipotential system at the site the secondary side
sockets do have correct potential. Relating equipment can have a three core cable (P, N,
Bonding) making it more simple and practical to do the connection of metal parts of relating
equipment (also external metal parts). No extra bonding arrangement required.
