Installation
MSA141
Analog Output Module
DE80032
Description and Dimensions
Terminal block for analog output
RJ45 connector to connect the module to the base unit with a CCA77x cord
RJ45 connector to link up the next remote module with a CCA77x cord
(according to application)
Grounding terminal
1 Jumper for impedance matching with load resistor (Rc), to be set to:
b , if the module is not the last interlinked module (default position)
b Rc, if the module is the last interlinked module
(1) 70 mm (2.8 in) with CCA77x cord connected
Connection
DE52182
Ground Terminal Connection
Use a tinned copper braid with a cross-section ≥ 6 mm² (AWG 10) or a cable with a
cross-section ≥ 2.5 mm² (AWG 12) and length ≤ 200 mm (7.9 in), equipped with a
4 mm (0.16 in) ring lug.
Check the tightness. The maximum tightening torque is 19.5 in-lb (2.2 Nm).
Connection of Analog Output to Screw-Type Connector
b One wire with a cross-section 0.2 to 2.5 mm² (AWG 24-12)
or
b Two wires with a cross-section 0.2 to 1 mm² (AWG 24-16)
Wiring Precautions
b Use shielded cables whenever possible
b Use a tinned copper braid to connect the shielding at the MSA141 end
DANGER
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH
b Only qualified electrical workers should install this equipment. Such work
should be performed only after reading this entire set of instructions
b NEVER work alone.
b Before performing visual inspections, tests, or maintenance on this
equipment, disconnect all sources of electric power. Assume that all
circuits are live until they have been completely deenergized, tested, and
tagged
b Use a properly rated voltage sensing device to confim that power is off.
b Screw tight all terminals, even those not in use.
b Isolate the temperature sensors from dangerous voltages.
Failure to follow these instructions will result in death or serious injury.
