Chapter 3: Installation

Installation

3.1 Mechanical Installation

3.1.1 Drawout Case The 750/760 is packaged with a drawout relay and a companion case. The case provides
mechanical protection for the drawout portion and is used to make permanent electrical
connections to external equipment. Where required, case connectors are fitted with
mechanisms, such as automatic CT shorting, to allow the safe removal of the relay from an
energized panel. There are no electronic components in the case.

FIGURE 3–1: Case Dimensions

To prevent unauthorized removal of the drawout relay, a wire lead seal can be installed
through the slot in the middle of the locking latch. With this seal in place, the relay cannot
be removed. Even though a passcode or setpoint access jumper can be used to prevent
entry of setpoints and still allow monitoring of actual values, access to the front panel
controls may still need to be restricted. As such, a separate seal can be installed on the
outside of the door to prevent it from being opened.
