Emerson HSP121BT-1RU Installation Manual

Edco HSP-121BT1RU

Internal Mount 120 VAC Protection

The Edco HSP-121BT1RU is an advanced 3-stage hybrid, solid state power line
protector. Features such as noise filtering, common mode and normal mode
suppression, nanosecond reaction time, power line tracking, and compression
screw terminations, make the Edco HSP-121BT1RU an excellent choice in
commercial and industrial applications.

The Edco HSP-121BT1RU offers a replaceable fuse designed to remove the load
(protected equipment) from the line if the unit is either overloaded or the internal
protection fails. This feature prevents surges from entering equipment through
a failed protector, not noticed by the user. Unlike models with only an indicator,
which may take weeks to notice, the Edco HSP-121BT1RU demands immediate
attention upon the unlikely occurrence of internal failure.

5. Make sure wiring from power sources properly connects to LINE side of HSP
(torque to 7 in. lbs.). Wiring from protected equipment must properly connect
to EQUIP side of HSP (torque to 7 in. lbs.).

6. Connect only to 120 VAC, 15 Amp Max., single phase, three wire circuit.

7. Indication of internal failure:

a. Indicator will extinguish.
b. Blown fuse will disconnect load from power source.

Warning

Disconnect AC source before replacing fuse. For continued protection against risk of fire,
replace only with same type rating of fuse (3 AB,15 A/250 V).

Avertissement

Débranchez la source de la tension AC avant que replacer le fusible. Pour assurer la
protection contre feu continuée, replacez le fusible avec exactement le même class du
