3.0 INSTALLATION
There are some precautions that must be observed when installing ANAFAZE 12LS.
WARNING! -- ELECTRICAL SHOCK DANGER
It is very important that all system power including
the power input be disconnected before servicing the
ANAFAZE 12LS. HIGH VOLTAGE MAY BE PRESENT EVEN WHEN
POWER IS TURNED OFF! To reduce the danger of elec-
trical shock always mount the 12LS in an enclosure
that prevents personal contact.
Although the ANAFAZE 12LS makes measurements of input signals that are referenced to
ground, the 12LS ground and other signal lines can inadvertently have power line or other high
voltage present even if the input power is turned off. This is possible, for example, if a
thermocouple was shorted to the AC power line.
WARNING!
USE CORRECT INSULATION TRIM LENGTH AND WIRE GAUGE
The correct insulation trim length is 1/4" or 5 mm.
Care must be taken to prevent contact between wires
and the case, which is grounded. The terminal
manufacturer has UL approval for #14 to #30 (AWG).
ANAFAZE recommends using #18 or #20 AWG.
To effectively use the terminals, the wire insulation should be trimmed so that the wire fits inside
the terminal with no bare wire exposed. Stranded wire should be tinned.
WARNING! -- SUPPORT CABLES
Power, input and output cables should be supported
to reduce strain on the terminals and to prevent
wires from being pulled out.
WARNING! -- PROVIDE CLEARANCE FOR VENTILATION
Always install the 12LS such that the slots in the
housing will have unrestricted air flow. Do not
block the slots with other equipment. If temporary
covers are placed over the 12LS during wiring ensure
they are removed prior to operation.
3.1 PHYSICAL CONSIDERATIONS
The ANAFAZE 12LS consists of a 1/8th DIN housing with a front plug in electronics module.
