Ransburg Evolver MicroPak Controller A10406 - Manual (Page 14)

SAFETY GROUND
Install the ground wire assembly supplied with the
Evolver MicroPak Controller from the ground stud
on the rear of the controller to a true earth ground.
For maximum noise immunity, cut the ground
wire assembly to the shortest length required and
reinstall the end lug before making connections.
LOW VOLTAGE CABLE
Standard Low Voltage Cable
(A11353-XX)
Plug the connector of the low voltage cable assem-
bly into the appropriate receptacle on the rear of
the controller (see Figure 3). P1 is the output for
the leftmost MicroPak control unit, when viewed
from the front, and P2 is the output for the rightmost
MicroPak control unit, if installed. When making
the connection, line the red dot on the connector
with the red mark on the receptacle and push
in until it clicks. To remove, simply pull back on
the knurled portion of the connector. Attach the
low voltage cable(s) to the stress relief bar using
TR-SSEM-200 cable ties (supplied) as shown in
Figure 3.
Junction Box Cables
(A11355-XX and A11356-XX)
The Evolver spray gun can be ordered with special
low voltage cables (A11355-XX and A11356-XX)
for splicing to a junction box. This is sometimes
done in the field, to reduce the amount of cable that
has to be replaced if a failure of the cable occurs.
The control unit and gun ends of these cables
attach as described in the standard low voltage
cable section above. Follow the instructions below
to wire the junction box ends of these cables:
Junction Box in Hazardous Location
If the junction box is in the hazardous location,
an explosion-proof junction box must be used. In
this case, connect the numbered wires of cable
A11356-XX to the same numbered wire of cable
A11355-XX using a terminal strip inside the ex-
plosion-proof junction box. Ensure the junction
box is grounded to earth ground. Connect wire
18 (braid) of cable A11355-XX to the junction box
(ground). Seal the cable in the explosion-proof
junction box using appropriate explosion-proof
fittings and sealing compound. The exposed area
of the cable braids must be located on the junction
box side of the sealing compound.
Junction Box in Non-Hazardous
Location
If the junction box is in a non-hazardous location,
then it is not necessary to use an explosion-proof
junction box. In this case, use the supplied cable
gland (A11357-02) and gland nut (A11358-02)
to secure the cables at their entry and exit to the
junction box. Install the cable gland in the junction
box and position the cable so that the spring of the
gland makes contact to the exposed braid of the
cable when the gland nut is tightened. Ensure the
junction box is grounded to earth ground. Connect
the numbered wires of cable A11356-XX to the
same numbered wire of cable A11355-XX using
a terminal strip inside the junction box. The braid
of cable A11355-XX will be grounded through its
contact to the cable gland spring and the grounded
junction box. Wire 18, therefore is unnecessary
and may be trimmed off. Connection in this manner
will ensure maximum noise immunity.
† The ground wire assembly MUST be con-
nected from the Evolver MicroPak Controller
ground stud to a true earth ground.
