Rockwell Automation 1485 PowerTap Connection - Manual

Installation Instructions
Bulletin 1485 PowerTap  Connection
IMPORTANT: Power: 15.0 Amps maximum total current; 7.5 Amps each trunk at 25
°
C (1485T–P2T5–T5).
Power: 6.0 Amps maximum total current; 3.0 Amps each trunk at 25
°
C (1485T–P2T5–T5C).
ATTENTION: Under some conditions of load
current and ambient temperature the fuse current
value should be decreased. As shipped, the
1485T–P2T5–T5 PowerTap connection is fused to
supply up to 7.5 Amps to one trunk line, the
1485T–P2T5–T5C 3.0 Amps.
Description
For power requirements on your DeviceNet

network,
Allen-Bradley is introducing its PowerTap connection. The
PowerTap connection is a passive coupling device used to
limit trunk current and is also used to permit the connection of
multiple power supplies to the trunk without mutual
interference.
