WARNING: Risk of electrocution. The PC40 240 VAC
Pattern Control can only be used in geographic regions
where 240 VAC with a grounded neutral is the industrial
standard. Failure
to connect the unit to a grounded neutral
can result in personal injury
or death. If 120 VAC with a
grounded neutral
is the industrial standard at your site,
consider using either the
PC40 AC Pattern Control (P /N 131
712), or the PC40 DC Pattern Control (P/N 131 709) and
PS40 DC Power Supply (P/N 131 739).
NOTE: In order to achieve an IP-54 Enclosure Rating (splash-resistant
environment), Nordson recommends that you route
all PC40 input and
output electrical connections through water-tight conduit and a junction
box. Use 1 in. (2.5 em) conduit fitting, and locate the conduit center line
1 in. (2.5 em) from the
wall.
1. Install a 1 in. (2.5 em) diameter strain relief connector (customer
supplied) in the
PC40 knockout.
2. Temporarily mount the front assembly to the back enclosure by doing
the following:
a. Loosen the six screws on the front assembly.
b. Remove the two top screws (Figure 3.5).
