Ensure that the exchange is securely sited and that all cables to the exchange are arranged
tidily and secured such that they cannot pull the connectors out of the exchange.
Check that all the modules are fully plugged into the chassis and correctly located in their
card guides before applying power for the first time. A module could become loosened from
the chassis if there was excessive vibration. Two metal strips F and G provide additional
stability for the modules and must be fitted to prevent the modules from vibrating out of
position.

Power Connections

Power connection is via a two-way terminal block mounted in the lower right hand side of the
bottom section of the MicroSwitch unit. When connecting to the terminals, the power leads
should be pushed through from under the unit where there are a series of holes. (Remove the
grommet from the relevant hole.) See Figure 3 below.
