Introduction

The STCSLAC12036 surge suppressor is specically designed for electronic instruments used by the water/

wastewater industries. It combines hybrid AC power protection and signal line protection in a NEMA-4X

polycarbonate enclosure.

HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH

• Apply appropriate personal protective equipment (PPE) and follow safe electrical work practices. See NFPA 70E,

NOM-029-STPS or CSA Z462.

• This equipment must only be installed and serviced by qualied electrical personnel.

• Turn o󰀨 all power supplying this equipment before working on or inside equipment.

• Always use a properly rated voltage sensing device to conrm power is o󰀨.

• Replace all devices, doors and covers before turning on power to this equipment.

• This equipment must be e󰀨ectively grounded per all applicable codes. Use an equipment-grounding conductor to

connect this equipment to the power system ground.

• Conrm that the Surge Protective Device voltage rating on the module or nameplate label is not less than the

operating voltage.

• On DC signal line protection do not apply more than 150mA

• On AC line protection do not apply more than 15 Amps of continuous current.

Failure to follow these instructions will result in death or serious injury.

WARNING: This product can expose you to chemicals including DINP, which is known to the State of

California to cause cancer, and DIDP which is known to the State of California to cause birth defects or other

reproductive harm. For more information go to: www.P65Warnings.ca.gov.

NOTICE

LOSS OF SURGE SUPPRESSION

• Make certain that Surge Protective Device is disconnected from the circuit it is protecting before conducting high

Installation

1. Turn off all power supplying this equipment before working on or inside equipment.

2. Conrm that the unit has the same voltage rating and conguration as the power system voltage and

power system voltage to which it will be connected.

For AC Power Connections:

a. Connect AC Power as Marked on Case using #14 - #12 AWG wire (L, N, G). Torque to

12 lb-in (1.35 N-m).

b. Keep 120 VAC Power feed separate from Low Voltage signal feed.

For Signal Line Connections:

a. Connect GND Terminal to Local Ground using #12 AWG wire minimum. Torque to 12 lb-in (1.35 N-m).

b. L1 and L2 – Connect for Signal Pair #1.

c. L3 and L4 – Connect for Signal Pair #2.

d. Terminals accept #24 - #14 AWG wire, torque to 3.47 lb-in (0.4 N-m).

3. Replace the barrier, cover/door and/or trim to the equipment.

4. Equipment may be re-energized after all the above steps are complete.
