RS-232 Serial Cable Installation
1. Loosen the cable gland connector(s) for the RS-232 serial cable. The gland connector(s)
for the RS-232 serial data are located on the back of the enclosure. Refer to Figure No. 12
for an illustration of the gland connector layout.
2. Slip the serial cable throught the gland connector and into the enclosure.
3. Remove 2" of the outer insulation jacket then remove 1/4" of insulation from each of the
wires (refer to Figure No. 16).
4. Connect each of the wires to the RS-232 Serial Data terminal block referring to the labels
on the circuit board for terminal connections. Refer to Figure No. 15 for terminal block
locations.
5. To terminate, insert the wire into the opening then tighten the cage clamp screw, locking
the wire in place. Repeat the procedure until all of the wires are in place.
AC Power Connection
It is the responsibility of the customer to have a qualified electrician install the
proper power cord plug which conforms to the national electrical codes and
local codes and ordinances.
Referring to Figure No. 12 for an illustration of the gland connector and conduit hole layout, use
the 1/2" conduit hole to bring the AC power into the enclosure. Use a seal-tite or rigid conduit
fitting to make a water-tight connection. NOTE! 18AWG copper wire should be used to connect
the AC power to the instrument.
1. With the AC wiring in the enclosure, remove 1/4" of
insulation from each of the wires (refer to Figure No. 16).
2. Connect each of the wires to the AC power terminal block
(P6) referring to Figure No. 17, the color code wiring table
below and the labels on the circuit board for terminal
connections. Refer to Figure No. 15 for terminal block
locations.
3. To terminate, remove the terminal block from the mating
connector, insert the wire into the opening, then tighten
the cage clamp screw, locking the wire in place.
4. Repeat the procedure until all of the wires are in place.
5. Reconnect the terminal block to the (P6) mating
connector.
6. Tighten all gland connectors, replace the rear panel and secure with the ten (10) screws
removed earlier.

IMPORTANT! Do not completely tighten the screws untill all neoprene washers
are touching the surface rear panel. Follow a diagonal pattern when tightening
the screws and neoprene washers. When completely tight, the neoprene washer
will protrude beyond the outside edge of the stainless steel part of the washer
