Chapter Two

Installation

Installation, Chapter 2 Watlow Power Series I 2.1

The following two chapters will explain how to install the Power Series

controller. Watlow power controllers are thoroughly tested before leaving the

factory, so the Power Series controller is ready to install when you receive it.

Chapters 2 and 3 describe the steps required to install the Power Series

controller. Refer to Chapter 2 for mounting information and Chapter 3 for input,

power, and load wiring of the Power Series.

Before beginning installation, read through these chapters to gain an under-

standing of the entire installation. Consider the installation carefully. Plan the

power, load, and input signal wiring before mounting the Power Series. Also

consider the cabinet space, controller dimensions, wire bending radius, and air-

flow. Use good wiring practices to minimize electrical noise problems.

WARNING:

To avoid potential electric

shock and other hazards,

all mounting and wiring

for the Power Series must

conform to the National

Electric Code (NEC) and

other locally applicable

codes.

Power Series Wire Bending Radius at Base Current and Ambient

Temperature Rating and Replacement Semiconductor Fuses

Minimum recommended wire sizes are based on the NEC 30°C ambient with not

more than three current carrying conductors in raceway or cable, while also

considering the Power Series 50°C enclosure temperature and semiconductor

fuse rating. Use copper conductors only.

The terminal lug wire range for all Power Series amperages is 350 MCM to 6

AWG. The recommended terminal torque is 180 in.-lbs. (20 Nm.). Refer to page

3.1 for torque guidelines.

NOTE: Ground must be

wired with the same size

wire as line and load

connections to a ground

of sufficient current

carrying capacity.

NOTE: Integral semicon-

ductor fuses do not

qualify as branch circuit

protection.
