SETUP/PHYSICAL INSTALLATION
This section explains how to configure and install the TTA ter-
mination unit. The required procedures are fuse installation,
dipshunt configuration, installing the termination unit, cable
connection and termination wiring.
Fuse Installation
One fuse is installed with every termination unit. Verify that
the fuse is installed in fuse clip F1 (see Figure
for the fuse
clip location). Fuse F1 is a 0.25 amp/250 volt fuse (part num-
ber 194776A12500).
Dipshunt Configuration
The dipshunts select the analog input type (voltage or current)
for the field device connected to the termination unit. Each
channel is independent. Configure a dipshunt by either cutting
straps or leaving straps uncut in certain sequences. Cut the
dipshunt straps using a standard shunt cutting tool (Amp Inc.
part number 435862-1). Always cut straps completely and
insure they do not touch adjacent straps. Install the configured
dipshunt into the desired socket (XU1 through XU8) on the
TTA circuit board.
WARNING
If input or output circuits are a shock hazard after disconnect-
ing system power at the power entry panel, then the door of the
cabinet containing these externally powered circuits must be
marked with a warning stating that multiple power sources
exist.
AVERTISSEMENT
Si des circuits d-entree ou de sortie sont alimentes a partir de
sources extrenes, ils presentent un risque de choc electrique
meme lorsque l'alimentation du systeme est debranchee du
panneau d'entree l'alimentation. Le cas echeant, un avertisse-
ment signalant la presence de sources d'alimentation multiples
doit entre appose sur la porte de l'armoire.
