General Information and Setup
Owner’s/Installation Manual for SMM 5
Setting Lockout
SMMs are equipped with a lockout provision. The SMM
can be set to enable lockout mode if load is identified as
non-essential and does NOT need to operate on backup
power during generator overload. Load can be an entire
subpanel of multiple branch circuits.
Proceed as follows to set SMM to enable standard lock-
out mode:
1. See Figure 2-2. Slide lockout switch (1) to LOCK-
OUT LOAD ON GENERATOR.
2. Set mode selector jumper (4) on the control board
as directed in Jumper Locations.
Jumper Locations
See Figure 2-2. The SMM control board is equipped with
two movable jumpers (2). Jumper locations are indicated
on the diagram:
• (3) Frequency Jumper
• (4) Mode Selector Jumper (identified on control
board as “Lock Out Jumper”)
The frequency jumper is factory set at the 60 Hz position.
The mode selector jumper is factory set at position “A”,
which is considered standard for most installations.
Jumpers should remain in place except when operating
the unit under either or both of the following conditions:
• Operating the unit at 50 Hz requires moving fre-
quency jumper to “50 Hz” position.
• For installations in areas with unstable utility
power, set mode selector jumper to position “B”.
To move a jumper:
1. Remove power.
2. Grasp jumper and pull straight up until it clears the
pins.
3. Move jumper to new location and press it gently
onto the pins until seated.
NOTE: To avoid bending or breaking pins, do not rock
jumper, use excessive force, or pull sideways to remove
it from the SMM control board.
