This bulletin should be used by experienced personnel as a guide to the installation of the Series 26M Control. Selection
or installation of equipment should always be accompanied by competent technical assistance. We encourage you to
contact Gems Sensors or a representative if further information is required.
Installation
1. Install octal socket in appropriate enclosure
using two #6 or #8 screws.
2. Install rail mount socket on appropriate rail
(DIN mount) in appropriate enclosure if appli-
cable.
3. Wire control per wiring diagram following
N.E.C and local codes.
4. Install control module in socket.

Torque all terminals and socket mounting screws to 7 in-lb max.
Mount the octal socket
(base) on rigid vertical
or horizontal surface
using #6 or #8 screws.
The control should be
mounted within an
enclosure of proper
NEMA integrity.
