Installing a Second TG-PEM
A second TG-PEM can be used to provide additional dry contact inputs. One TG-PEM provides up to 8 inputs,
while a second TG-PEM can provide a total of 9-16 inputs.
The mounting bracket and circuit board for a second TG-PEM will be mounted upside-down inside the TG-7
series enclosure when compared to the first TG-PEM device. A second set of screw holes are provided on the
bracket for use when the bracket is oriented this way.
Mounting Bracket
Before beginning the installation of a second TG-PEM, use one of the screws provided to pre-thread the screw
holes in the metal mounting bracket. While not required, this will make attaching the TG-PEM circuit board to
the metal bracket much easier. Make sure to pre-thread the holes that will be on the left when the bracket is
installed as shown below.
•
Remove the bottom-left mounting screw that holds the TG-7 series circuit board.
•
Orient the bracket according to the image below.
•
Insert the bracket at an angle so that the bottom mounting point slides under the board as depicted, and
the angled tab threads through the enclosure bump out.
•
Replace the TG-7 series circuit board mounting screw to secure the bracket.
