Model 4802A
NOTE - Zero Two series modules require air circulation to avoid excessive heat build-
up. If chassis are stacked vertically within an enclosure, forced air circulation may be
required. The Control Modules are, to a great extent, immune to electromagnetic
interference (EMI). However, they should not be mounted in close proximity to radio
transmitters or similar equipment.
If the installation is subjected to a strong Radio Frequency Electromagnetic Field (10V/m
@ 27-1000Mhz), the Control Module may respond with a display deviation of +/-10%
FSD. This deviation will disappear following removal of the field. Functionality is
otherwise unaffected.

Rear Terminal Connections

All wire connections to the Model 4802A are made to the terminal block located at the
2
rear of the chassis. The terminal block accepts 16 AWG to 20 AWG (1.5mm
to
2
0.75mm
), stranded or solid core wire.
14 AWG wire may be used if it is properly stripped according to Figure 20.
Figure 20 – Wire Strip Length
CAUTION - Contact with PC Board components should be avoided in order to prevent
damage by static electricity.
To connect wires to the terminal block on the Model 4802A, loosen the desired screw,
insert the stripped end of the wire and tighten. (Alternate connector styles available –
contact the factory).
