Mounting the 7866 Digital Controller/Indicator

Introduction
The 7866 Controller/Indicator can be mounted on a panel using the mounting kit supplied. Adequate space
must be available at the back of the panel for installation and servicing activities.
The controller is considered "rack and panel mounted equipment" per the following safety standards:
For US, ANSI/ISA S82-1994
For Canada, CAN/CSA – C22.2 No. 1010.1-92
For Europe, EN610101-1
Conformity with these standards requires the user to provide adequate protection against a shock hazard. The user
shall install this controller in an enclosure that limits OPERATOR access to the rear terminals.
If the controller is used in a manner not specified by Honeywell, the protection provided by the equipment may be
impaired.
Physical Considerations
The controller can be mounted on either a vertical or tilted panel using the mounting kit supplied. Adequate
access space must be available at the back of the panel for installation and servicing activities.
