SES65 120/240 AC PANEL PROTECTOR
DESCRIPTION
AC surge protector permanently connected to main service panel.
The SES65 120/240 features a compact chassis, visible and audible diagnostics, easy installation and a five-year warranty (see
back page).
Designed for 120/240 V, 1 Phase, 2 wire plus ground
and 120/240V, 1
Phase, 3 wires plus ground applications.
APPLICATION
The unit protects against electrical surges that can cause damage
to electric and electronic equipment. Catastrophic failures and
gradual component degradation can be caused by high voltage
surges, which are generated by harsh weather conditions, external
power anomalies, or day-to-day electrical component switching.
The SES65 120/240 will protect electrical equipment against
surges caused by the above factors. However, for effective equipment protection, we recommend using secondary protectors at
the location of the equipment you would like to protect.
SAFETY CONSIDERATIONS
A certified electrician must install the protector. Installation
must follow applicable electrical codes. Failure to follow installation instructions may result in personal injury, equipment
damage and invalidation of the warranty.
Your electrical system must be grounded per Article 250 of the
NEC. Surge protection works best when a secure ground is
established. Check grounding before restoring power.
!
CAUTION:
When installing or removing this protector from service, disconnect power.
Failure to do so may result in equipment damage, serious injury or death.

MOUNTING INSTRUCTIONS
Install unit according to local electrical codes, or using instructions below. Lead
lengths must be as short as possible to keep voltage drop to a minimum. Trim
excessive length to provide for lowest wire impedance to the surge protector. In
the event of lightning or other power transients, a one-foot reduction of
connecting lead length can reduce the let-through voltage reaching downstream
equipment by 100 volts or more.
Use a threaded nipple or thin-wall conduit to connect the unit to the service panel.
Feed the wires through into the conduit and into the panel.
Using the screw holes on the back plate corners, mount unit as close as possible
to the service panel (Figure 1).

Installation BEFORE The Main Disconnect
WARNING: REMOVE THE METER OR OTHERWISE DISCONNECT THE AC POWER BEFORE
BEGINNING THE INSTALLATION!!!
The SES65 120/240 should be installed by qualified and authorized personnel.
USE A TEST LAMP TO CONFIRM THAT THE POWER HAS BEEN REMOVED!!
The SES65 120/240 protector is UL Listed for installation either before or behind the main
service disconnect. The mechanical installation to the meter pan or meter side of the service panel is as described in figures 1- 3, as close as possible to the wiring between the
meter and the service disconnect.
SES65 120/240 CONNECTIONS:
1. The SES65 120/240 wires should be connected to the points
"B" in figure 4. The
connections can be made at the meter socket
or on the wiring to the main disconnect.
2. Connect the green (ground) wire to the service raceway, the ground bus, or any other
part of the grounding electrode system. The ground wire should be kept as short as
possible.
3. Connect the 2 black wires to the two phase terminals of the
meter socket or to the
conductors to the disconnect. An insulated tap connector such as ILSCO KUPLER IPC 4/0-#6
is a fast and easy way to connect the black (phase) wires to the service conductors.
4. Check the connections!
5. Replace the meter, or turn the AC power switch back on.The two green lights on the
unit should come on, confirming that the connections are correct and there is power
to both phases.
Installation AFTER The Main Disconnect
1. The SES65 120/240 should be installed by a qualified electrician.
2.
Turn "OFF" and lock out the power to the enclosure in which the unit is to be installed.
3. Connect the green wire to the ground bus or connector.
4. Install the appropriate 2 pole, 30 ampere circuit breaker or lug kit (See table) to the
panelboard or meter combination device. If a sub-feed lug kit is available, it is a better
and more economical connection than a breaker.
5.
Connect the black leads to the load terminals of the circuit breaker
or lug kit and tighten
to the required torque.
6. Double check connections, then reconnect power.
7. When both LEDs are on, the protector is functioning as desired.
