To install primary AC wiring, perform the following procedures:
● Shut off the primary AC power supply line to this location.
● Open the front door of the Electronic Enclosure (if locked, use a 4 mm Allen wrench to unlock
it.)
● Install circuit breaker, conduit and primary AC wiring appropriate for the area safety
classification. The breaker should be located near the Maxum II. Label the Breaker to make
sure that the circuit is clearly identifiable. See Application Drawing Package Block & Utility
Diagram sheet for power requirements.
● Run the 12 AWG (115 VAC air bath or airless) or 14 AWG (230 VAC air bath or airless or any
modular oven configuration) wiring through a cable gland or conduit (per local codes) to the
Electronic Enclosure interior. Allow enough extra cable to be run into the Electronic
Enclosure to be certain it reaches the proper connection point. Use enough cable so that
there will be no sharp cable bends when the terminations are made.
● Connect the wiring to internal points as shown in Air Bath or Airless AC Input and Fuses
(Page 22) or Modular Oven Model Power Connections (Page 23).
3.5.4 Signal Cables
Best practice for connecting the Maxum II to external equipment is to use shielded cables. This
may be required in many installations. This does not apply if the wiring runs through metal
conduit.
Note
All digital output (DO) lines with inductive loads must have transient suppression at the
inductive load.
Cable installation
All cables to the Maxum edition II must be shielded. The
shield must be 360-degree and connected to ground only at
one end, normally at MAXUM's metal cable glands. The
shield must end at the cable gland. Mounting the cable to the
cable gland:
● Loosen nut (2) of a suitable cable gland and remove the
sealing ring (1)
● Push cable into chromatograph as far as required
● Remove the outer insulation jacket (D) and shield screen
from end of cable up to screwed gland. Expose 2 cm (1")
of screen
● Connect screen around the sealing ring (1) and tighten nut
(2). Make sure that the screen makes good electrical
contact with the metal of the cable gland mounted to the
analyzer chassis.
