Removing and replacing the enclosure door

The door on a Security Enclosures is removable. It is often convenient to remove the enclosure door before

other mounting and wiring tasks. This also provides a lighter unit for initial mounting to the wall.

Procedure 1 Removing the door of a Security Enclosures.

Step 1

Open (and if necessary, unlock) the door, opening it about half way.

Step 2

Slide the door toward the top of the unit, until the hinge tabs on the door clear the hinge pins on the

enclosure.

Step 3

Lift the door away from the enclosure.

Procedure 2 Replacing the door of a Security Enclosures.

Step 1

Align the hinge tabs on the door above the hinge pins on the left wall of the metal casing.

Step 2

Slide the door toward the bottom of the unit, until the door hinge tabs fully seat onto the hinge pins.

Step 3

Close the door and check for proper fit.

Pre-Installation

Mounting and Dimensions

Locate and mark mounting holes

The Security Enclosures has four main mounting holes on its back wall—the upper two holes are keyhole types.

It is often convenient to mark the location of the mounting holes in the wall before continuing.

Procedure 5 Locate and mark enclosure mounting holes.

Step 1

With the enclosure door opened or removed, position the enclosure on the wall in the location where

it will be installed.

Note For locations and dimensions of enclosure mounting holes, see Figure 2 on page 7 for medium

sized enclosures (EC-SEC-EN-MED, EC-SEC-EN-MNP) and Figure 3 on page 7 for large sized

enclosures (EC-SEC-EN-LRG, EC-SEC-EN-LNP).

Step 2

Carefully mark the mounting hole locations, and remove the enclosure.

Step 3

Drill the needed pilot holes in the wall, for example to install wall anchors (if needed), and install wall

anchors if used. For example, drill 5/16" (8mm) holes for wall anchors.

Mounting and Dimensions

Note Mount the Security Enclosures in an indoor location only. For more environmental requirements, see

the “UL Requirements” section in the EC-BOS-602/616AX Security Hardware Installation Guide.

Following pre-installation tasks, the enclosure is ready for wall mounting. Install fasteners in all 4 mounting

holes, tightening securely. For example, if wall anchors were installed in 5/16" holes, use four #14 anchor bolts,

or other appropriate fasteners, as needed to securely fasten.

• See Figure 2 on page 7 for medium enclosure (EC-SEC-EN-MED, EC-SEC-EN-MNP) wall mounting

dimensions.

• See Figure 3 on page 7 for large enclosure (EC-SEC-EN-LRG, EC-SEC-EN-LNP) wall mounting

dimensions.

After mounting, replace the enclosure door if removed, see

“Removing and replacing the enclosure door,”

page 4.

Note A short, green, grounding wire with ring ends is included in the enclosure’s hardware bag. After

mounting and final replacement of the door, install this wire on the studs inside the door and on the

enclosure’s left side, near the lower hinge. Use the included #6-32 keps nuts to fasten the wire ends to

the studs. For the location of this grounding wire, see Figure 2 and Figure 3 on page 7.

Earth Grounding and Power Wiring

EC-SEC-EN-MED and EC-SEC-EN-LRG Ground and Power Wiring

Earth Grounding and Power Wiring

The Security Enclosures must be connected to a nearby earth ground.

• If a unit with an integral power supply, wire ground to the unit’s 3-position terminal strip, along with power

wiring. See the next section “EC-SEC-EN-MED and EC-SEC-EN-LRG Ground and Power Wiring”.

• If a unit without an integral power supply, make an earth ground connection to a designated grounding

stud inside the enclosure. See “EC-SEC-EN-MNP and EC-SEC-EN-LNP Ground Wiring,” page 9.

EC-SEC-EN-MED and EC-SEC-EN-LRG Ground and Power Wiring

The integral power supply in a EC-SEC-EN-MED or EC-SEC-EN-LRG enclosure provides 30W of regulated

15Vdc power to a EC-BOS-nAX and/or its connected expansion modules. Input voltage is 120Vac to 240Vac,

single phase.

Warning A 120Vac or 240Vac circuit powers the Security Enclosures power supply. Disconnect power

to this circuit before installation to prevent electrical shock or equipment damage.

Caution • AC power wiring must be routed in conduit. AC power cords routed through cable clamps are

not permitted.

• Size power conductors in accordance with the local regulating authority, such as the NEC.

• Do not exceed the 30W supply capacity of the Security Enclosures power supply by the

powered devices. Door strike power, as well as power for other loads switched by the

EC-BOS-nAX and/or its expansion modules, should always be provided from a different

source.

Procedure 6 (EC-SEC-EN-MED or EC-SEC-EN-LRG only) Power and ground wiring.

Step 1

Remove power from the AC circuit being wired to the Security Enclosures power supply—see

previous Warning on page 8.

Step 2

Route the AC circuit wiring (Line, Ground, Neutral) through conduit in the top left area of the enclosure,

and terminate to the 3-position terminal strip. See Figure 4 on page 8.

Note Do not remove the plastic cover of the power supply. The power supply is pre-wired to the

3-position terminal strip, along with the enclosure chassis.

Step 3

Before restoring power to the Security Enclosures power supply, complete any other wiring

connections on the EC-BOS-nAX and its accessory modules.

Note 15Vdc output power is provided on the 6-position connector of the power supply. If installing an

EC-BOS-nAX controller, you mount it on the top DIN rail in the enclosure, plugged directly into the power

supply connector. If the enclosure contains only expansion modules, you populate the top DIN rail first.

If installing a model EC-SEC-EN-LRG enclosure, note the included 6-wire harness that supplies 15Vdc power

and communications to any modules you mount on the lower DIN rail.

EC-SEC-EN-MNP and EC-SEC-EN-LNP Ground Wiring

For units without an integral power supply, wire earth ground to the enclosure as described below.

Procedure 7 Grounding the EC-SEC-EN-MNP or EC-SEC-EN-LNP enclosure.

• Wire earth ground to the enclosure, using a minimum 14 AWG (2.5mm2cross section) wire attached to a

designated grounding stud inside the enclosure.
