Mounting
1. The OVRHMSU series is intended to be installed in a control
cabinet or similar enclosure with a degree of protection of at
least IP20 (NEMA 1). The enclosure shall provide protection
against accidental contact by requiring a tool, key or similar
device to ensure only Qualified Personnel are allowed access
to exposed live (energized) circuits. Metal enclosures shall be
adequately bonded (grounded).
2. Remove all power feeding the site of the OVRHMSU
connection.
3. The OVRHMSU series is designed for installation in or
Adjacent installation requires a sealed enclosure. Care should
be taken to ensure exposed terminals do not come in contact
with personnel.
4. Within the equipment to protected, mount the OVRHMSU
securely to the enclosure or other mounting surface using the
holes provided in the opposite corners.
5. Using 10 AWG (5MM2) conductors and #8 insulated ring
terminals, connect the OVRHMSU series using the provided #8
(m4) screws. The maximum torque to be applied to the

Electrical connections
1. The OVRHMSU must be protected via a circuit breaker
with a maximum capacity of 30 amps.
2. Determine the location of the AC source supplying power
to the load.
3. The OVRHMSU is to be installed in series between the AC
power source and the equipment to be protected.
4. Using the appropriate phase, neutral and ground
conductors, connect the incoming power source to the
input terminals of the OVRHMSU.
5. Connect the Line 1 conductor to the L1 terminal
of the OVRHMSU.

7. Connect the PE (Ground) conductor to the G terminal
of the OVRHMSU.
and load, connect the Line 2 conductor to the L2 terminal
of the OVRHMSU.
9. Repeat Steps 5 through 8 on the load side of the
OVRHMSU series SPD.
10. For best performance, the SPD should be connected
as close as possible to the load. Additionally, load side
conductors should not be run in the same conduit, cable
tray, or cable trough as the input conductors.
Apply power to the device once proper installation has been
completed. An illuminated LED indicates proper operation of
the device. See Figures 1 and 2 for OVRHMSU line diagram.
This unit contains no serviceable parts.
