Models: OVRHSP-60kA–100kA with
option 1 and OVRHSR series
For these models, the Form “C” contacts come pre-wired with
254 mm (36 in.) of #20 AWG conductors.
See Figure 7 for the Form “C” wiring and contact configuration.
Use butt splices within the panelboard to connect the Form
“C” leads to the user’s monitoring circuits. Alternatively, install
a junction box between the OVRHSP(SR) series and the
panelboard to connect Form “C” leads to user’s monitoring
circuits. If the Form “C” contacts are not used, user has the
option of either cutting off the leads or coiling up the leads and
saving them for potential future use. Consult applicable local
codes to ensure proper installation.

Models: OVRHSP-120kA–400kA
For these models, the Form “C” contacts must be wired by
the installer.
See Figure 8 for the Form “C” contact configuration and
terminal location on the monitor board. The annotations on the
diagram match the markings on the terminal block.
The installer must route the monitoring conductors to the
terminal blocks on the main monitoring board. Tighten screws
on terminals to 0.4 Nm (3.5 in-lbs.). This terminal block will
accept wire sizes #28 AWG–#16 AWG. #18–#20 AWG is
recommended.
