WIRING CONNECTIONS
terminal pins located on the back of the
unit. The terminal pins are on 0.100"
center lines and can be mated with the
RLC Model HWK7 cable assembly or
many
connectors. When wiring the unit, refer to
Figure 3 to identify the wire position with
the proper function.
should be observed when running the
signal wires. A length of wire can act like
an antenna, and the closer it is to a source
of electrical noise, the more it becomes
susceptible to that noise.
1. Never run signal wires in the same conduit or raceway with A.C. power lines,
2. Signal wires within enclosures should be routed as far away as possible from
3. When shielded wire is used, connect the shield to the common of the MDMV
4. Connect common of the MDMV to machine ground at one point only.

that are damaged by static electricity. Before handling the assembly,
discharge stray static electricity on your body by touching an earth ground
point. It is also important to handle the unit by the bezel assembly only.
Additionally, if it is necessary to handle a circuit board, be certain that hands
are free from dirt, oil, etc., to avoid circuit contamination that may lead to
malfunction.
