!
Caution
When connecting up the module, keep to the installation guidelines in Section 1.5.
!
Caution
The IE/AS-INTERFACE LINK PN IO may only be connected when the AS-i power
supply unit is turned off.
Connectors for the AS-i Cable(s)
The IE/AS-i LINK has two connectors for the AS-i cables (line 1 and line 2). Each
is connected over a 4-pin plug with two + and two − contacts that are jumpered
internally.
This allows the IE/AS-i LINK to be looped into the AS-i cable.
!
Caution
The permitted current loading of the AS-i connection contacts is 3 A. If this value
is exceeded on the AS-i cable, the IE/AS-INTERFACE LINK PN IO must not be
looped into the AS-i cable but must be connected with a tap line (only one pair of
connectors of the IE/AS-i LINK is used).
