17.4 Mounting the Relay
Case
The procedure for mounting the relay case is as
follows:
1. Cut and drill the mounting panel to the dimensions
shown in Figure 17.6 (for the 7UT512 relay) or
Figure 17.7 (for the 7UT513 relay).
2. To make the case lighter and thus easier to
handle, remove the relay module(s) from the case.
3. Insert the relay case into the panel from the front,
so that the case's mounting flange is on the
outside of the panel. Make sure that the case is
right-side up (the letters and numbers of the labels
on the back of the case should be right-side up).
Secure the case to the panel with four screws or
bolts.
4. Connect a braided ground strap to either of the
grounding screws on the back of the case
(see Figure 17.5).
5. Insert the relay module(s) back into the case and
re-attach the front panel.
