INSTALLATION

INTRODUCTION

Upon receipt of a relay, check the model and style number against the requisition and packing list to
ensure that they agree.

If there is any evidence of shipping damage, file a claim with the carrier and notify Basler Electric.

If the relay won’t be installed immediately, store it in its original shipping carton in a moisture- and dust-
free environment.

MOUNTING

Because the relay is of solid-state design, it does not have to be mounted vertically. Any convenient
mounting angle may be chosen.

Cutting and Drilling Dimensions

Panel cutting and drilling dimensions for semi-flush mounted relays (style number xxx-xxx-xxxxF) are
shown in Figure 4-1. Panel drilling dimensions for projection mounted relays (style number xxx-xxx-
xxxxP) are shown in Figures 4-2 and 4-3. Figure 4-2 illustrates the panel drilling dimensions for double-
ended, projection-mounted cases. (Double-ended cases have terminals at both the bottom and top ends
of the case. BE1-87G relays with three-phase current sensing (style number Gxx-xxx-xxxxx) are supplied
with a double-ended case. Figure 4-3 illustrates the panel drilling dimensions for single-ended, projection-
mounted cases. (Single-ended cases have terminals only at the bottom end of the case. BE1-87G relays
with single-phase current sensing (style number Sxx-xxx-xxxxx) are supplied with a single-ended case.

Case Dimensions

Side views showing semi-flush mounted case dimensions are provided in Figures 4-4 and 4-5. Figure 4-4
illustrates a side view of the case dimensions for a double-ended, semi-flush mounted case. Figure 4-5
illustrates a side view of the case dimensions for a single-ended, semi-flush mounted case.

Side views showing projection mounted case dimensions are provided in Figures 4-6 and 4-7. Figure 4-6
illustrates a side view of the case dimensions for a double-ended, projection mounted case. Figure 4-7
illustrates a side view of the case dimensions for a single-ended, projection mounted case.

Rear views showing semi-flush mounted case dimensions are provided in Figures 4-8 and 4-9. (The rear-
view dimensions for semi-flush mounted cases and projection-mounted cases are identical.) Figure 4-8
illustrates a rear view of the case dimensions for a double-ended case and Figure 4-9 illustrates a rear
view of the case dimensions for a single-ended case.

A front view showing the dimensions of the case cover is provided in Figure 4-10.

Stabilizing Reactor

For three-phase relays, the stabilizing reactor consists of a module attached to the rear of the mounting
case. For projection mounting or convenience, the stabilizing reactor module can be removed and
relocated. To remove the stabilizing reactor, remove the four screws that secure the module to the
mounting plate. The mounting plate is separated from the case by removing the two hex-head bolts.

When the stabilizing reactor is relocated, it should be rewired in accordance with the connection diagrams
shown later in this section.

The overall dimensions of the stabilizing reactor are shown in Figure 4-11. A side view showing the
dimensions of a semi-flush mounting case with attached stabilizing reactor is provided in Figure 4-12.
