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).
