Installation Procedure
To mount the Watlow Series 1500:
1. Make a panel cutout per the dimensions in Figure 10.
2. Remove the Series 1500 chassis from its case by turning the front panel screw
CCW. Grip the bezel firmly and pull the control from the case.
3. Place the case in the cutout you just made.
4. Attach the mounting brackets either to the top and bottom, or to both sides of the
unit.
5. Tighten the screws on the ends of the mounting brackets to hold the case
securely against the back of the panel.
6. Insert the control chassis into its case and turn the front panel screw CW to hold
the chassis in place.
If you have a Series 1500 with data communications:
Fasten your DB-15 male connector with two 4-40 brass screws to the 1500's DB-
15 female on the rear of the unit. Do not overtighten screws.
Electrical Connections and Wiring
”
Figures 14 and 15, on the following two pages, show you how to connect the Watlow
Series 1500 to your load or system. Study the strip connections carefully before
beginning the hook-up. Be sure to use these jumpers on the Power Supply termi-
nals: For 115VAC, jumper 32 to 35 and jumper 33 to 36. For 230 VAC, jumper 33 to
35. Attach Chassis Ground to 34.
If you wish to disable Channel 2, Figure 18 will show you how to do that.
Figure 19 provides the pin configuration for units equipped with RS-422/RS-423 data
communications. On these models the serial communications interface is through a
DB-15, D-Type, female connector located on the 1500's backplane. This connector
is tapped to accept two 4-40 brass screws for attaching the male plug.
