3.0 INSTALLATION
There are some precautions that must be observed when installing the ANAFAZE 8 PID:
WARNING-ELECTRICAL SHOCK DANGER
It is very important that all signal lines including the power input be
disconnected before servicing the ANAFAZE 8 PID. HIGH
VOLTAGE MAY BE PRESENT EVEN WHEN POWER IS
TURNED OFF.
Since the ANAFAZE 8 PID can make measurements of input signals that are not
referenced to ground, the ANAFAZE 8 PID ground and other signal lines can have
power line or other high voltage present even if the input power is turned off. This could
happen, for example, if a thermocouple was inadvertently shorted to the AC power line.
WARNING - USE CORRECT INSULATION TRIM LENGTH
AND WIRE GAGE
The correct insulation trim length is 1/4" or 5mm. Care must be
taken to prevent contact between any wires and the case which is
grounded. The terminal manufacturer has UL approval for #14 to
#30 AWG (American Wire Gage). ANAFAZE recommends using #18
or #20 AWG.
To effectively use the plug-in 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 connectors and to prevent them from being pulled out of the
terminal strips.
3.1 PHYSICAL CONSIDERATIONS
The ANAFAZE 8 PID consists of a single PC board with an aluminum housing. Nine
rear slots are provided for plug-in option boards, one for communication and eight for
control outputs.
3.1.1 MOUNTING [SEE PHYSICAL LAYOUT ON NEXT PAGE]
WARNING ELECTRICAL SHOCK DANGER
Always mount the ANAFAZE 8 PID so that access is controlled to
prevent any contact with the terminals. HIGH VOLTAGE MAY BE
PRESENT EVEN WHEN POWER IS TURNED OFF.
