1.0 Introduction

The CP-10 Control Unit can monitor one channel of gas detection when connected to a Sensor Transmitter(S/T). The CP-10 is NOT in an enclosure rated for use in a Class I, Div 1, Groups B, C, D classified area and can not be installed in a hazardous location.

Features of the CP-10:

 continuous monitoring of the target gas  continuous LCD display of gas and vapor concentrations  menu driven operational and maintenance controls  audio and visual alarms indicate unsafe conditions  alarm relay contacts available on terminals  a fault relay and visual fault alarm  alarm acknowledgement capability including audio defeat  mA outputs for target gas

OTE

: All specifications stated in this manual may change without notice.

3.0 Installation of the CP-10

The CP-10 is supplied with a strain relief for a power line cord. Use this fitting or connect a conduit fitting when supplying power to the unit.

OTE

: This control panel is NOT rated for hazardous locations. The control panel must be located in a NON-Hazardous area.

3.1 Mounting CP-10

Mount the CP-10 instrument on an appropriate vertical surface, leaving room for lid to be opened, using the mounting holes provided. Avoid areas with excessive vibration or temperature extremes. The holes in the bottom of the enclosure are 0.18 inch in diameter and form a 6.44″ x 4.47″ rectangle. See Figure 3

It is recommended to use #8 drywall anchors and screws for mounting the CP-10 to a drywall/sheetrock surface.
